Abstract

Aging usually reduces muscle capacity in the core muscles of the body causing a reduction in functional abilities and activities of daily living. In the present investigation, we evaluated the effect of an exercise regimen on strength training in the core muscles, balance, and reach. Thirteen subjects underwent 20 minutes of exercise per day, 3 days a week, for a period of 1 month using a 6 Second Abs machine (Savvier, LP, Carlsbad, CA), eliciting exercise on the rectus abdominis, transversus abdominis, and back extensor muscles. Balance and functional reach were assessed before and after the exercise program. Before exercise, the average maximum reach in the subjects was 15.4 ± 5.2, 16.9 ± 5.7, and 15.7 ± 4.8 cm for reach in the forward, right, and left directions, respectively. After training, reach increased to 22.4 ± 5.9, 20.6 ± 4.0, and 22.5 ± 5.3 cm in the respective directions. Associated with that movement, during maximum reach in the forward, right, and left directions, the reach angle of the body changed from 1.91° ± 2.76°, 2.31° ± 0.9°, and 0.9° ± 3.1° before training to 5.33° ± 1.83°, 4.72° ± 1.83°, and 2.42° ± 1.1° after the 1-month training program, showing a corresponding increase associated with the increased reach of these subjects. Not only were reach and the critical angle at which the subject exceeded his or her limit of stability increased, but tremor was reduced significantly for these subjects after training. The results show that even if older individuals are engaged in a basic fitness program, training is very beneficial to increasing their independence and functional activities of daily living.

... Regarding the positive effects of exercise training on balance, a great deal of research has focussed on balance improvement protocols using a myriad of training methods, including strength training, weight training, core stability, and neuromuscular training (Petrofsky et al. 2005;Carpes et al. 2008). Core stability training is a modality of training that focuses on trunk muscles. ...
... Enhancing trunk muscle forces provided stability in the core body, leading to postural performance improvements (Kibler et al. 2006;Borghuis et al. 2008;Larivi ere et al. 2015;Prieske et al. 2016). To date, studies have mostly explored and reported positive effects of core stability training on postural control and balance (Petrofsky et al. 2005;Carpes et al. 2008). For instance, 12 weeks of strength training for the core body using a Swiss ball increased dynamic balance in women (Sekendiz et al. 2010); however, the effects of core stability exercises on the balance of deaf children undergoing an 8-week training were not reported in the literature. ...
... The findings of the study indicated that PT and CST groups decreased the number of errors during BESS with open and closed eyes, leading to improvements in balance in deaf students. These findings are in line with previous studies (Lindsey and O'Neal 1976;Lewis et al. 1985;Petrofsky et al. 2005;Carpes et al. 2008;Sato and Mokha 2009;Hessari et al. 2011;Hyun et al. 2014;de Oliveira et al. 2015) which examined the effects of proprioception and core stability training on static balance and found significant effects. In open and closed eyes states, both experimental groups indicated similar significant training effects. ...

Purpose Children with hearing impairment are unable to speak and may suffer from some physical problems such as weakness in postural performance ability and development. The aim of the current study was to explore the effects of proprioception versus core stability training for an 8-week period followed by a 6-month detraining protocol on the balance performance of deaf students. Materials and methods This is a randomized controlled trial design of three groups in blinded evaluators. The study was conducted at the school gym. A total of 30 participants, of male deaf students, were randomized into three groups: (1) one group receiving proprioception training (PT, n = 10), (2), one group receiving core stability training (CST, n = 10) for 8 weeks, and (3), and control group (CON, n = 10). The Balance Error Scoring System (BESS) test and Y-balance test assess static and dynamic balance at pre- and post-training following a 6-month detraining. Results Post 8 weeks of training intervention, PT and CST values showed significant improvements in both static (p = 0.001) and dynamic (p = 0.001) balance. Following the 6-month detraining, only the PT group maintained their improvements in both the static and dynamic balance tests (p = 0.348) and the CST group showed decreases in the balance tests (p = 0.034). Conclusions The results indicate that 8 weeks rehabilitation program (PT and CST) is an optimum training modality to enhance balance in deaf students and PT induces more training effects than CST for maintaining training benefits following the detraining

... Poor balance and physical readiness in the elderly is a multifactorial subject [12]. Since irreversible consequences such as falling caused by reduced balance threat the lives of elderly people [11], prevention of falling is the best treatment. Different studies indicated that along with age increase, strength and endurance of the muscles also reduced, which in turn results in reduced balance, elevated body swing, and consequently, increased risk of falling [11]. ...

Purpose: The elderly patients undergoing hemodialysis who developed end-stage renal failure are at higher risk for falling and its critical outcomes compared with their healthy counterparts due to of poor balance, reduced muscle endurance, and sedentary lifestyle. The current study aimed at evaluating the effect of selected core stability exercises on balance and muscle endurance in the elderly patients undergoing hemodialysis. Methods: In the current quasi-experimental study, a total of 30 patients undergoing hemodialysis with the mean age of 62.24±6.51 years, the mean hemodialysis duration of 29.4±18.44 months, and the history of falling at least once during the last year were selected using the purposive convenience sampling method and then, the subjects were randomly allocated into 2 groups of intervention (n=15) and control (n=15). To assess the static balance, dynamic balance, and muscle endurance in the patients, the stork stand test, the timed Up and Go test (TUG), and the sit-to-stand-to-sit test for 60 seconds (STS-60) were used, respectively. The selected core stability exercises were performed for the intervention group in 6 weeks, three 45-minute sessions per week. To analyze data, the repeated measures analysis of variance (RM ANOVA) with SPSS version 22 was used; P<0.05 was considered the level of significance. Results: Results of the current study indicated significant differences between the groups in terms of static balance, dynamic balance, and muscle endurance (P<0.001). In other words, the implemented exercises significantly affected the studied variables. Conclusion: Based on the obtained results, the therapists can suggest the core stability exercises as a safe and functional strategy to improve balance and muscle endurance in patients undergoing hemodialysis, which may result in increased independence of action and reduced risk of falling due to loss of balance.

... [3] Muscle strength is lost in the axial muscles i.e. core muscles along with distal muscles which make it difficult to maintain balance. [4] Balance is the ability to maintain the body's center of gravity within the limits of stability as determined by the base of support. [5] The ability to maintain balance is an integrated task of neuromuscular, central nervous system and sensory system. ...
... Control group did not show any significant change in Berg Balance Scale, Y -balance Test (anterior,posteromedial, posterolateral) and Functional Reach Test. As Ageing is an on-going process, there are normal age associated changes taking place in the body which leads to impairments in balance [1] .Also, there is decline of physiological capacities and deterioration of ability to respond to stress in this period which increases vulnerability of the older adults to various impairments due to ageing process [4] . So there was no change seen in the control group. ...

Objective: Fall is defined as unintentional loss of balance that leads to failure of postural stability. Around 30% of older adults aged over 65 years have an episode of falls each year.. All postural control components undergo changes with ageing. Any impairment in neuromuscular, central nervous system and sensory system leads to fall. So the aim of present study was to determine the effects of Core stabilization exercises on balance performance in older adults. Methodology: Sixty participants both males and females aged between 65-75 years were divided into 2 groups, Experimental and Control group (n=30). Experimental group performed core stabilization exercises 5 times a week for 6 weeks, while control group carried on their routine daily activity for 6 weeks. Berg Balance Scale (BBS), Y-Balance Test, Functional Reach Test were assessed at the baseline and after 6 weeks of intervention. Results: Statistical analysis revealed that Experimental group showed significant improvement in BBS, Y-Balance Test and Functional Reach Test scores with (p ˂ 0.05) post 6 weeks of intervention. Control group showed no significant improvement in the scores. Conclusion: Core stabilization exercises had significant improvement on balance variables in experimental group when compared to control group.

Conclusion: The study concluded that, there is positive correlation between knee osteoarthritis (OA) and foot posture index. The abnormal foot posture was commonly seen in patients with OA Knee grade 3 and 4.
... [2] These disabilities, secondary to the normal aging process, can lead to loss of balance and poor gait in the older population [2] . Balance is the ability to maintain an upright posture during static and dynamic tasks which requires complex interactions between peripheral and central factors such as vision, somatosensation, vestibular sensation, motor output, and musculature [3] . Along with interaction of the nervous and musculoskeletal system, balance and postural control also requires interaction between vestibular system, visual system and somatosensory system. ...
... It is therefore hypothesized that addition of these exercises in balance training will prove as aid in elderly having balance impairment [4] . Falls and fall related injuries can cause limited mobility and functional decline leading to disability and may have a negative effect on the socioeconomic status and quality of life (QOL) in elderly individuals [3] . ADLs are frequently impaired due to weakness in core muscles such as the rectus abdominis, transversus abdominis, and the internal and external oblique muscles. ...
... These improvements in trunk muscle function are not surprising, given that Huber training required constant trunk muscle activation during isometric pushing/pulling efforts (50-75% of MVC) in various directions. Our results are in concordance to those reported by other authors that examined the effects of core strength or core stability training on trunk muscle function in older adults (Granacher et al., 2012;Cruz-Ferreira, Fernandes, Laranjo, Bernardo, & Silva, 2011;Petrofsky, Cuneo, Dial, Pawley, & Hill, 2005). Granacher et al. (2012) reported 21-53% increase in trunk muscle strength following 9-week core training under unstable conditions in older individuals. ...
... Granacher et al. (2012) reported 21-53% increase in trunk muscle strength following 9-week core training under unstable conditions in older individuals. Petrofsky et al. (2005) showed that 4-week core strength training program increased strength of trunk flexors and extensors of seniors by 33-36%. Kahle and Tevald (2014) recently reported 44% increase in abdominal muscle endurance following core strengthening program in healthy older men and women. ...
... Each person was evaluated 3 times with the first 2 evaluations (days 1 and 2) separated by 1-2 days, and the third 1 (day 3) after an interval of approximately 6 weeks. A 6-weeks interval is considered as the minimum duration of a therapeutic exercise intervention to demonstrate a clear improvement of strength (28,29). All muscle torque tests were performed by 3 experienced examiners (cS, MW, RH) and conducted at the same time of day to reduce effects of diurnal variation. ...
... Although the wide LoAs observed in our study probably induce high relative reliability values, the precision of the dAVId ® test devices is sensitive enough to detect changes that may be induced by a rigorous strengthening intervention programme of more than 4 weeks in elderly persons (28,29) and more than 9 weeks in young persons (16,40), where significant improvements in trunk muscle strength can be expected. the precision of the tests may, however, be insufficient to identify real improvements if healthy volunteers perform a short or less rigorous exercise programme or if healthy volunteers start a training programme with an initially high trunk strength performance baseline (43). ...

Objective: To determine the short- and long-term test-retest reliability of maximum isometric trunk moment measurements in healthy volunteers over 50 years of age, to compare these results with those from volunteers younger than 50 years, and to test whether volunteers' anticipatory emotional state affects the precision of these measurements. Methods: Forty-two older persons (21 females; age range 50-90 years) and 44 younger persons (19 females; age range 18-49 years) performed maximum isometric trunk extensions, flexions, and rotations using dynamometers (DAVID, Fi, David Health Solutions Ltd, Helsinki, Finland). They repeated the tests after 1-2 days (short-term) and at 6 weeks (long-term). Retest-reliability was evaluated for age- and gender-specific subgroups, with assessment of intraclass correlation coefficient (ICC2,1) , standard error of measurement, smallest real difference, and smallest real difference, in percent. Results: For the elderly group, smallest real difference, in percent values varied up to 33% and were similar to those obtained from young volunteers. Precision of the trunk rotation tests was lower than that of trunk flexion or extension. Retest agreement exceeded 0.75 (ICC2,1) for all tests, with no relevant differences observed between gender- and age-specific subgroups. Neither participants' motivation nor their anticipatory emotions correlated with the individual coefficients of variation of the trunk muscle moment measurements. Conclusion: Isometric maximum trunk extension and flexion moment measurements taken from healthy persons > 50 years old are as reliable as those from persons < 50 years old, and can be expected to enable an acceptable level of detection of expected changes in muscle strength parameters as a result of planned exercise interventions.
... Central stability exercises can enhance proprioception in the core region, leading to improved balance. Studies indicate that 6 to 12 weeks of central stability training can significantly enhance balance performance (37)(38)(39)(40)(41)(42).

2021) The association between trunk muscle endurance, balance and falls self-efficacy in women with osteoporotic vertebral fractures: an exploratory analysis from a pilot randomized controlled trial, Disability and Rehabilitation, 43:16, 2268-2274, ABSTRACT Background: Trunk muscle endurance may be associated with balance and falls self-efficacy for people with osteoporosis. However, all previous studies have examined trunk muscle strength rather than endurance. Purpose: To explore the relationships between trunk muscle endurance and standing balance and falls self-efficacy for women with vertebral fractures. Materials and Methods: This is an exploratory, secondary analysis of baseline data of a pilot randomized controlled trial in Ontario, Canada. Thirty-one women with osteoporosis, aged 65 years or older, with at least one vertebral fracture were included. The associations between balance (Balance Outcome Measure for Elder Rehabilitation) and trunk muscle endurance (Timed Loaded Standing Test) and falls self-efficacy (Falls Efficacy Scale International) and trunk muscle endurance were tested via Spearman rank order correlation with Fisher's z transformations. Results: Trunk muscle endurance was correlated with better balance performance on the Balance Outcome Measure for Elder Rehabilitation [Spearman correlation coefficient, 0.71; 95% confidence interval: 0.47-0.85; p < 0.001], but not with falls self efficacy (Spearman correlation coefficient;-0.22; 95% confidence interval:-0.53 to 0.14; p ¼ 0.23). Conclusions: Trunk muscle endurance was moderately associated with better standing balance performance but not falls self-efficacy, highlighting the importance of trunk muscle endurance for standing balance for older adults with osteoporosis and vertebral fractures.

Background: Trunk stability is key in controlling body balance and movements. Trunk Stabilization Exercises (TSE) and Conventional Trunk Exercises (CTE) are performed to improve dynamic balance. The authors have previously reported that dynamic balance was improved by a 12-week and 6-week TSE program. However, there is a dearth of research on its immediate effect on dynamic balance in trained soccer players. Objective: To compare the immediate effeect of TSE with that of CTE on dynamic balance in trained soccer players. Methods: Forty-eight male soccer players (24.60 ffi 1.38 years) participated in this crossover study, wherein each participant took part in three exercise sessions: TSE, CTE, and No Exercise control (NE), each consisting of three steps: pre-test, intervention and post-test, with an interval of one week between each exercise condition. To assess dynamic balance, the Y Balance Test-Lower Quarter (YBT-LQ) score in the anterior, posteromedial, and posterolateral directions was measured before and 5 minutes after each intervention. Results: The YBT-LQ composite score was significantly improved after TSE (0.51) as compared to CTE (0.22) and NE (0.04) (p < 0.05). Furthermore, in TSE and CTE conditions, YBT-LQ scores of the posterolateral and posteromedial directions significantly improved at the post-test (p < 0.05). Conclusions: Both TSE and CTE are effective in immediately improving dynamic balance; however, TSE showed greater improvement as compared to the latter. Immediate improvements in the posteromedial and posterolateral directions of the YBT-LQ were demonstrated after performing the TSE and CTE.

Objective: The elderly have a decrease in muscle power and cognitive functions, leading to a higher risk of falling. The core stabilization exercise is a standard exercise for the elderly, but is considered as non-interesting and has no immediate feedback. On the other hand, active video gaming is new technology, more interesting and provides immediate feedback. Thus, the objective was to compare the effectiveness of core stabilization exercise (CSE) and active video gaming (AVG) on dynamic balance, core and lower limb muscle strength and reaction time in elderly people. Material and Methods: This study was a single-blind randomized controlled trial design; conducted from January to April, 2019. The participants were 34, healthy, elderly patients; who were randomly assigned to either the CSE group (n=17) or AVG group (n=17). All participants received a training program consisting of 60 minutes, 3 times a week, for 6 weeks. The CSE group received a core stabilization exercise program, while the AVG group received video gaming with balance control on a moveable platform (Sensamove® , the Netherlands). The participants were assessed for dynamic balance, core and lower limb muscle strength, and reaction time at pre-, two, forth, and sixth week. Results: The AVG group showed superior and significant difference to the CSE group in dynamic balance after forth (p-value=0.004; 95% confidence interval (CI), -0.94 to -0.11) and sixth week (p-value=0.001; 95% CI, -1.22 to -0.25) of training, and reaction time after forth (p-value=0.028; 95% CI, -37.89 to –0.24) and sixth week of training (p-value= 0.026; 95% CI, -72.08 to -10.13). However, within group comparison, after sixth weeks of training, the CSE group had significantly increased in core (p-value=0.020; 95% CI, 1.01 to 21.55) and lower limb muscle strength (p-value=0.008; 95% CI, -2.68 to -0.39). In addition, the AVG group had significantly increased in dynamic balance (p-value=0.001; 95% CI, -2.18 to -0.66), lower limb muscle strength (p-value=0.001; 95% CI, -2.38 to -0.66), and reaction time (p-value= 0.007; 95% CI, -120.99 to -22.64). Conclusion: Active video gaming showed better effectiveness than the core stabilization exercise in both dynamic balance and reaction time. Between before and after six weeks of training, the core stabilization exercise increased in core and lower limb muscle strength. In addition, active video gaming increased in dynamic balance, lower limb muscle strength and reaction time. So, active video gaming can be added in generic rehabilitation for improvement of muscle strength, reaction time and balance.
... For ACSM, these types of exercises should systematically be part of the training sessions of all healthy adults (ACSM, 2010;Scurati et al., 2016;Seo et al., 2012;Stephenson & Swank, 2004) to prevent any spinal and lower limbs injuries (Kliziene et al., 2015;Petersen & Nittinger, 2014;Hicks et al., 2005;Petrofsky et al., 2005;Hodges et al., 2005;Willson et al., 2005): ACSM's advices, in practice, support the effectiveness and systematic nature of this type of exercise in order to improve these functional relationships and to extend senior quality life; other Authors view Core stability exercises to prevent falls by increasing the static and dynamic balance ability (ACSM, 2010; Kahle & Tevald, 2014;Granacher et al., 2013;Kang, 2015). ...

The COVID-19 infection has particularly affected older adults. Clinical observations in this population highlight major respiratory impairment associated with the development or aggravation of the patient’s frailty state. Mr. P is a 93-year-old frail patient, hospitalized after a COVID-19 infection. The assessment process of this patient has been supported by an innovative multi-systemic tool developed in view of the COVID-19 clinical consequences and a systemic evaluation of motor functions by the Frail’BESTest. This process allowed a mixed clinical picture associated with significant respiratory distress (linked with acute respiratory distress syndrome) and an evident motor frailty. The care plan was developed accordingly, and four assessments were done in the same manner until Mr. P returned home. This case report allows us to see a holistic COVID-19 clinical picture, showing the different axes of clinical reasoning to enhance the rehabilitation process. Furthermore, this case report illustrates the importance of rehabilitation in the COVID-19 context.

Introduction. External focus instruction and self-controlled feedback have beneficial effects on motor learning. The purpose of the present study was to investigate the benefits of combined effects of external focus instruction and self-controlled feedback on balance performance in older adults. Material and Methods. Forty older adults (mean age: 63.21 ± 3.6 years; all female) were selected and randomly divided into 4 groups: self-controlled feedback, external attention, external attention/self-controlled feedback and control group. The task of standing on the platform of the stabilometer device and trying to keep the platform horizontally as much as possible was performed in each 30-sec. trial. The participants of self-controlled group received feedback on the timing of balance after the trials. In the external focus of attention, participants noticed the signs that were located horizontally ahead of their feet. The test was conducted in two sessions. In the acquisition phase, 10 trials of 30 seconds were performed and the retention test was completed 24 hours later as 5 trials of 30 seconds. Results. The results of mixed ANOVA on time data as an indicator of balance in the acquisition phase showed that the mixed group of external focus of attention and self-controlled feedback had better performance than the other groups (p = 0.004). In the retention test, the results of mixed ANOVA showed that the participants in the combined group of external focus and self-controlled feedback had better performance than the other groups (p = 0.006). The external focus of attention and self-controlled feedback performed similarly, and both were superior to the control group (p < 0.05). Conclusions. The results of this study, supporting the OPTIMAL theory of motor learning in the elderly, showed that the combination of two factors of external focus and self-controlled feedback has a double advantage over the presence of each of the factors. Therefore, it is suggested that the combinations of external focus instructions and self-controlled feedback should be used to improve performance and motor learning in the classes of practical and clinical rehabilitation fields.

Key points. Exercise-based core stability training interventions demonstrate considerable emphasis on traditional types of strength training components and only few exercise programs consider motor learning components to enhance function in older adults. It remains unclear whether additional motor learning components are more beneficial for effecting core stability training related outcomes in comparison to traditional exercise programming. Exercise practitioners and therapists should be aware that structured exercise programs for core stability training can be flexible in design, however, come with the probability of impacting differently on core stability training related outcomes in older adults. Background. To influence core stability related functioning in elderly, several types of resistance training interventions may be performed. Different types of core stability training will differently effect on training related outcomes. The objective of this systematic review is to investigate the effect of motor learning training strategies in comparison to traditional strength training for core stability. Methods. Selected articles were identified from MEDLINE, EMBASE, CINAHL, PsycINFO and Cochrane. Studies were included if published in English and aimed to train core stability. The studies should target subjects aged 60 years and older. Results. The search strategy yielded 13 studies that met the inclusion criteria; 11 describing traditional trunk strength exercising programmes and 2 using motor learning training strategies. The results do not allow favoring one training approach against the other due to insufficient studies comparing the two training approaches. Conclusion. Currently available literature does not present a wealth of information about the best strategy for core stability training in seniors. The limited availability of high-quality prospective studies that used a comparison between traditional and training approaches that use elements of motor learning warrants targeted future research investigating and comparing the effects of these approaches.
... For sports and many other functional tasks, the core body is a key chain in the beginning-toend sequence in the transmission path from the ground to the upper limbs. Inefficiency in the central part of the body may affect individual performance and facilitate the occurrence of injuries (21). Both athletes and sedentary individuals are at the risk of hip joint damages. ...

Abstract Background and Aim: Autism children are susceptible to movement disorders, weakness of physical fitness, decrease of balance, and stability beause of inactive life style and weakness. Recently, the role of the muscles of the back and pelvis, as part of the core stability, is being considered, because these muscles control motion of the lower limbs based on closed kinematic chain. The purpose of the present study was to investigate the relationship between lumbar-pelvic function and static and dynamic balance in children with autism spectrum disorders. Materials and Methods: Participants included 32 boys aged 6-10 years selected according to available sampling and normalized based on Gylyam Garz Diagnostic criteria. For evaluating static and dynamic balance and lumbar-pelvic function, modified stork, walking heel to toe, and step down tests were used, respectively. Results: The Pearson correlation revealed a significant correlation between the lumbarpelvic function and static and dynamic balance. Conclusion: According to the results, it can be suggested that lumbar pelvic function be improved as an important part of core stability, and static and dynamic balance and rehabilitation programs be developed to better help children with autism spectrum disorder.

Background: one of the most frequent determinants of long-term disability in the adults is Stroke which may affect the normal functioning of trunk and hence may disturb balance. Objective: to assess the effects of “Abdominal Drawing-in Maneuver” and “Diaphragmatic Breathing Maneuver” in improving the stability of trunk in stroke patients. Methods: A quasi-experimental study including 36 patients with confirmed diagnosis of the first incident of stroke was conducted. Patients were assigned randomly in two groups ADIM and DBM. Outcome measurements were evaluated using the “Trunk Impairment Scale”. Results: after 4 weeks of training; “Trunk Impairment Scale” score improved significantly. Between groups comparison shows that trunk stability significantly improved in the group DBM as compared those in the group ADIM. Conclusion: it may be concluded that Diaphragmatic Breathing Maneuver can be an effective technique in improving trunk stability in stroke patients.
... The results of our study have implications for balance training in older adults with osteoporosis, especially since current recommendations for falls prevention focus almost exclusively on lower extremity training [36]. Nine previous studies have found improvements in balance and functional measures after incorporating trunk muscle training into exercise programs [37][38][39][40][41][42][43][44][45]. However, only one of these was completed with people with osteoporosis [42]. ...

Background: Trunk muscle endurance may be associated with balance and falls self-efficacy for people with osteoporosis. However, all previous studies have examined trunk muscle strength rather than endurance. Purpose: To explore the relationships between trunk muscle endurance and standing balance and falls self-efficacy for women with vertebral fractures. Materials and Methods: This is an exploratory, secondary analysis of baseline data of a pilot randomized controlled trial in Ontario, Canada. Thirty-one women with osteoporosis, aged 65 years or older, with at least one vertebral fracture were included. The associations between balance (Balance Outcome Measure for Elder Rehabilitation) and trunk muscle endurance (Timed Loaded Standing Test) and falls self-efficacy (Falls Efficacy Scale International) and trunk muscle endurance were tested via Spearman rank order correlation with Fisher’s z transformations. Results: Trunk muscle endurance was correlated with better balance performance on the Balance Outcome Measure for Elder Rehabilitation [Spearman correlation coefficient, 0.71; 95% confidence interval: 0.47–0.85; p < 0.001], but not with falls self efficacy (Spearman correlation coefficient; –0.22; 95% confidence interval: –0.53 to 0.14; p = 0.23). Conclusions: Trunk muscle endurance was moderately associated with better standing balance performance but not falls self-efficacy, highlighting the importance of trunk muscle endurance for standing balance for older adults with osteoporosis and vertebral fractures. • Implications for Rehabilitation • Older adults with osteoporosis and vertebral fractures who have better trunk muscle endurance may also have better standing balance. • There was no association between trunk muscle endurance and how confident a person is that they will not fall while completing various activities of daily living. • Trunk muscle endurance training could be included as part of a standing balance rehabilitation program for this population.
... 9 The incidence of falling continues to rise after middle age 2 , due to a physiological deterioration associated with age, including: the impairment of cognitive, sensory systems, reduction in lower limb muscle strength, muscle capacity in the core muscles of the body, proprioception, joint range of motion, reaction time, and speed of movement. 7,10,11 These changes result in worse dynamic balance, which affects the activities of daily life along with increasing the risk of falling. 7,12,13 Therefore, effective exercise interventions for improving balance are important in order to prevent falling in middle-aged as well as older adults. ...

Objectives: The aim of this study to compare the effectiveness of the balance training program (BTP), and the core stabilization program (CSP), on dynamic balance in healthy middle-aged individuals. Material and Methods: This study was a single-blind randomized controlled trial design. Forty-two healthy middle-aged participants were randomly assigned to the BTP group (n=21), or the CSP group (n=21). Participants in both groups received an intervention program (balance training or core stabilization) 3 times a week, for 60 minutes, over 6 weeks. The primary outcome was the dynamic balance measured by the timed up and go test. The other outcomes were: core muscle endurance, muscle strength of the lower extremities, the flexibility of the lower back and hamstring muscles, and gait variables. The measurements included: the prone bridge endurance test, 5 times sit to stand test, sit and reach test and a wireless movement monitoring inertial sensor system, respectively. All outcomes were measured at baseline, and then after 6 weeks. The data were analyzed by the Independent Sample t-test between groups, and the paired t-test within either group. Results: After 6 weeks, there was no statistically significant difference between the groups in either dynamic balance, or other variables, however, a statistically significant difference was found in core muscle endurance (p-value=0.003). In so saying, the BTP group, statistically significant improvements were found only in core muscle endurance, the flexibility of the lower back and hamstring muscles, and gait variables from pre- to post-test. Moreover, in the CSP group, there was a statistically significant difference from pre- to post-test in all measured outcomes. Conclusion: The Core stabilization program is not superior to a balance training program, for the improvement of dynamic balance. Although, after 6 weeks of training, the study found that the Core stabilization program was effective for improving dynamic balance. This finding may point out that the Core stabilization program helps improve balance in a middle-aged person

The aim of this study was to assess the effectiveness of a multimodal exercise program to increase trunk muscle morphology and strength in older individuals, and their associated changes in functional ability. Using a single-blinded parallel-group randomized controlled trial design, 64 older adults (≥60 years) were randomly allocated to a 12-week exercise program comprising walking and balance exercises with or without trunk strengthening/motor control exercises; followed by a 6-week walking-only program (detraining; 32 per group). Trunk muscle morphology (ultrasound imaging), strength (isokinetic dynamometer), and functional ability and balance (6-Minute Walk Test; 30 second Chair Stand Test; Sitting and Rising Test; Berg Balance Scale, Multi-Directional Reach Test; Timed Up and Go; Four Step Square Test) were the primary outcome measures. Sixty-four older adults (mean [SD]; age: 69.8 [7.5] years; 59.4% female) were randomized into two exercise groups. Trunk training relative to walking-balance training increased (mean difference [95% CI]) the size of the rectus abdominis (2.08 [1.29, 2.89] cm2 ), lumbar multifidus (L4/L5:0.39 [0.16, 0.61] cm; L5/S1:0.31 [0.07, 0.55] cm), and the lateral abdominal musculature (0.63 [0.40, 0.85] cm); and increased trunk flexion (29.8 [4.40, 55.31] N), extension (37.71 [15.17, 60.25] N), and lateral flexion (52.30 [36.57, 68.02] N) strength. Trunk training relative to walking-balance training improved 30-second Chair Stand Test (5.90 [3.39, 8.42] repetitions), Sitting and Rising Test (1.23 [0.24, 2.23] points), Forward Reach Test (4.20 [1.89, 6.51] cm), Backward Reach Test (2.42 [0.33, 4.52] cm), and Timed Up and Go Test (-0.76 [-1.40, -0.13] seconds). Detraining led to some declines but all outcomes remained significantly improved when compared to pre-training. These findings support the inclusion of trunk strengthening/motor control exercises as part of a multimodal exercise program for older adults.
... The purpose of this study was to evaluate the thickness and symmetry of TrA in regards to occurrence of low back pain (LBP) as well as to evaluate the efficacy of sonofeedback in learning and control of abdominal muscle activity. Taking into account the number of disorders that result in abnormal (delayed, asymmetric or decreased) activation of the TrA muscle, training of this muscle is considered to be an important component of the rehabilitation process for patients with LBP (39,8), scoliosis (40), incontinence (30), as well as in improving the autonomy and performance of daily activities in the elderly (41). According to this research, the LBP affects as many as 60% of students. ...

PURPOSE: The purpose of the study was to evaluate thickness and symmetry of Transversus Abdominis muscle (TrA) during rest and activation with the use of Rehabilitative Ultrasound Imaging (RUSI) and the assessment of sonofeedback effectivness in learning and control of TrA activity. MATERIAL AND METHODS: The study was conducted on 28 healthy subjects (17 women and i 11 men) aged 19-22 years (mean 21±1,08 years). The subjects undergone RUSI assessment considering thickness of TrA in rest and during contraction. Basing on results the Activation Ration and Percent of Muscle Change were calculated. RESULTS: Mean thickness of TrA in rest was 3,19 mm among women and 4,37 mm among men. During controlled activity thickness of TrA increased by 69% on right side and by 64% on left side and respectively by 70% and 64% among men. The results showed a significant difference in TrA thickness between right and left side at rest and during contraction among men. During sonofeedback recorded thickness of TrA was significantly higher comparing to results without control of sonofeedback. TrA activity was lower in the group with low back pain and it was 64%, while in pain-free group the activity was 72%. CONCLUSIONS: 1. RUSI is an effective method to evaluate the morphology and activity of the Transversus Abdominis muscle at rest and during controlled activation; 2. The decrease in thickness and activity impairment of TrA is related to the occurrence of low back pain; 3. The use of sonofeedback enables significant improvement in activation and equalization of TrA asymmetry.

Background and Aims The anterior cruciate ligament injury in athletes is associated with disorders related to balance and postural control. Poor balance is a predictor of lower limb injury in athletes. This study aims to investigate the different neuromuscular parameters that affect the static and dynamic balance in adolescent male football players with Dynamic Knee Valgus (DKV). Methods This is a correlational study. Participants were 83 adolescent male football players with DKV (age: 12.63±0.72 years, height: 1.69±0.07 meters, weight: 23.23±7.74 58 kg, BMI: 20.32±2.38 kg /m2), who were selected using a purposive sampling method. The presence of DKV was assessed by the squat test. The strength of the trunk and hip muscles was assessed by manual muscle testing (MMT), trunk endurance by the McGill test, and range of motion (ROM) of hip and ankle joints by a goniometer. Moreover, the static and dynamic balances were evaluated by the Bass Stick test and Y balance test, respectively. The Pearson correlation test was used to examine the relationships at a significance level of 0.05. All statistical operations were performed by SPSS software, version 24. Results The results of the present study showed a significant relationship between static balance and the study parameters (P≤0.05) except for trunk flexion strength (P=0.16) and ROM (P<0.05), hip flexion ROM (P=0.83), hip extension ROM (P=0.96), hip abduction ROM (P=0.77) and ankle dorsiflexion ROM (P=0.94). The dynamic balance at anterior-posterior direction had a significant relationship with trunk endurance and left-side plank (P=0.07) and strength (P=0.05), but not with plank test score (P=0.45). The dynamic Y balance at posteromedial direction had a significant relationship with all variables except for 60° flexion (P=0.40), plank (P=0.53), left-side plank (P=0.09), and trunk extension strength (P=0.23). The results of the study also showed the significant relationship of dynamic balance at posterolateral direction and the total score of Y balance test with total trunk endurance test score (P=0.03, P=0.003) and right-side plank (P=0.005, P=0.001). Moreover, trunk extension strength and hip strength variables had a significant relationship with posterolateral dynamic balance and total Y balance test score (P≤0.05). Furthermore, the ROM of ankle dorsiflexion had a significant relationship with balance at the posteromedial (P=0.03), posterolateral (P=0.02) directions and the total Y balance score (P=0.02). Conclusion Static balance of adolescent male soccer players with DKV has a significant relationship with trunk endurance, trunk strength and thigh strength. There is a significant relationship between dynamic balance and trunk endurance, trunk strength, hip strength, and ankle dorsiflexion ROM.

Background and Aims Balance disorders and frequent falling are the important problems in the elderly, which is directly related to changes in their body structure and function. Many studies have been conducted to find new and safe ways to improve the balance of the elderly. This study aims to compare the effects of Pilates exercises on stable and unstable surfaces on the functional balance and core stability of older women. Methods In this quasi-experimental study, the study population includes all older women living in private nursing homes, in Rasht, Iran. Of these, 36 women aged 60-75 years were selected by a convenience sampling method and randomly assigned to three groups of control, Pilates on stable surface, and Pilates on unstable surface. The variables were assessed using the Fullerton advanced balance test, timed up & go test, and the McGill core endurance test. Experimental groups performed Pilates exercises for 8 weeks, while the control group performed their routine daily activities. Data were analyzed by one-way analysis of variance, t-test and Bonferroni’s post hoc test. The significance level was set at 0.05. Results There was a significant difference between the experimental and control groups; however, there was no significant difference between the experimental groups performed exercises on stable and unstable levels (P>0.05) Conclusion It is recommended to use Pilates exercises on stable or unstable surfaces for older women, especially residents of nursing homes with low mobility, to achieve their personal autonomy.

Background and Aims: This study aimed at the effects of 8 weeks TRX exercises and core stability exercises in the stable level on the landing pattern, the stability of the core area, and the balance of girls football players. Methods: Thirty athletes with trunk defects were screened by Tuck Jump test and selected as a statistical sample. Finally, assigned to two groups of 15 subjects at a stable level and varying level training. Both groups participated in pretest and post-test. Both groups training sessions for 8 weeks and three weeks each week on core stability training at both sustained (stable) and unstable (TRX). This study used the core stability practice protocol in the training section at a stable and unstable level. The static and dynamic balance were evaluated by BESS and Y tests, respectively. McGill’s endurance tests also evaluated the endurance of the core region. In addition, landing mechanics were assessed using the Landing Error Score System test. ANCOVA test was used to compare the differences between the research variables by two types of training. The stability of the core body was used in two groups of training (stable and TRX) and a t-test for correlating the changes within the group. Results: The results of the analysis of t-test showed that in the results of the stable training (P≤0.001) and TRX (P≤0.001) effect on score of the error of landing error, LESS, flexion 60 °, Sorensen, Right Plank, static balance and total dynamic balance score. In the post-test, there are significant differences between the two groups in the TRX and stable levels in LESS, Sorensen, static balance in the state stand on two legs on a soft surface and stand in the Tandem on a soft surface (P≤0.05). Conclusion: the results of this study showed that the use of core stability training at a stable and unstable level by helping to improve the landing jump activity, as well as improving muscular balance and endurance, can be eliminated by modifying some of the risk factors associated with an ACL injury to prevent Lower limb non-limiting injury in athletes with trunk defects.

Objective: Since direct foot kick is one of the most important strikes in Jeet Kune Do, its effectiveness depends on both the force of the hit and balance control during and after the hit execution, this study undertaken to examine the effect and persistence of eight-week of core stability training on balance and force of a direct foot kick of elite young male Jeet Kune Do (Wushu) athletes. Methods: 24 elite young Jeet Kune Do athletes were randomly assigned to an experimental and a control groups. The experimental group performed the core stability training program for eight consecutive weeks. Static (stork test), dynamic test (tandem test) and force of a direct foot kick of the athletes in both groups were measured in three stages including before, after (eight weeks of core stability training) and a 4-week follow-up detraining period. Results: The results showed that core stability training had a significant and persistent effect on static and dynamic balance. However, the training program had no significant effect on the force production of a direct foot kick after a 4-week of detraining period. Conclusion: It seems that the core stability training program improves the neuromuscular system function by strengthening the muscles of the core area. This in turn prevents the dislocation of the center of gravity outside the base of support and decreases its oscillation (displacement), therefore, as a result of persistence effect of the program, balance ability and direct kicking power improves.

[Purpose] To investigate the effect of a postoperative program with added trunk muscle training for proximal femoral fractures. [Participants and Methods] Postoperatively, patients admitted to a convalescent rehabilitation ward were categorized into a control group (normal physiotherapy; 9 patients) and an intervention group (added trunk muscle training; 9 patients). Before and after the 4-week intervention, patients' trunk function, walking ability, balance function, lower limb muscle strength, pain, and fall self-efficacy scale were measured, and changes between the two groups were compared. [Results] In the intervention group, trunk function (thickness of the abdominal rectus, thoracic erector spinae and external abdominal oblique muscles, and endurance of the abdominal muscle), walking ability (timed up-and-go test), and balance function (Berg Balance scale) significantly improved compared to the control group. [Conclusion] These findings suggest that trunk muscle training may promote the recovery of walking ability and balance function in postoperative patients.

Background and Aim: The core stabilizer muscle weakness can have a negative effect on the balance. On the other hand, the stability of the core area as a connection with the effective transfer of force produced in the lower extremity to the upper limb through the trunk leads to better exercise. Purpose: The present study was carried out to compare the effects of core stability trainings on stable and unstable levels on the female athletes' balance. Materials and Methods: The statistical society of the current study consisted of 30 female athletes from Guilan province who were intentionally selected to take part in the study. They were divided into two groups of 15: stable training and unstable levels of training for 6 weeks, 3 sessions per week. Static balance dynamic balance were evaluated using BESS and Y balance tests, respectively. To analyze the difference in balance between the athletes in the two groups, statistical analysis of covariance and t-correlation analysis were used. Results: The results of the study showed a significant effect of both training protocols on static and dynamic balance (P = 0.001). Also, the results of covariance analysis indicated that training on unstable level had higher efficiency on static and dynamic balance (P <0.05). Conclusion: The results of the present research suggest that, given the difference between the two types of training in affecting the balance component, in addition to the fact that both types of body stabilization trainings can be useful to improve the balance by strengthening the muscles that are Spinal and pelvic controls, coaches and athletes should use unstable levels of core stability training to improve balance.

Twenty subjects were evaluated to test the effectiveness of a portable abdominal device (6 second Abs Machine (Savvier, LP, Carlsbad,CA). The relationship between work and peak surface EMG (sEMG) of a traditional crunch was compared to six different exercises using the 6 Second Abs Machine (SAM). sEMG was used to evaluate the bilateral rectus and oblique muscles. The work accomplished (EMG amplitude x time of contraction) in a crunch was 9 times greater using the SAM device for the Rectus and 11 times greater for the Oblique muscles (p<0.02). The sitting reverse exercise was 40 times greater at the oblique muscle and 23 times greater for the rectus musculature (p<0.02). Average peak sEMG of a SAM crunch compared to a traditional crunch was 39% greater at the Rectus and 37% at the Oblique (p<0.02). The sitting reverse crunches increased to 78% at the Rectus and 113% at the Oblique (p<0.001) on the SAM compared to the traditional crunch. The SAM provided much greater exercise for the rectus and oblique muscles when performed in a seated and supine position than traditional crunches.

Participation in exercise programs is heartily recommended for older adults since the level of physical fitness directly influences functional independence. The aim of this present study was to investigate the effects of supervised Pilates exercise training on the physical function, hypothesizing that a period of Pilates exercise training (PET) can increase overall muscle strength, body composition, and balance, during single and dual-task conditions, in a group of post-menopausal women. Twenty-five subjects, aged 59 to 66 years old, were recruited. Eligible participants were assessed prior and after 3 months of PET performed twice per week. Muscular strength was evaluated with handgrip strength (HGS) test, 30-s chair sit-to-stand test (30CST), and abdominal strength (AST) test. Postural control and dual-task performance were measured through a stabilometric platform while dynamic balance with 8 ft up and go test. Finally, body composition was assessed by means of dual-energy X-ray absorptiometry. Statistically significant improvements were detected on HGS (+8.22 %), 30CST (+23.41 %), 8 ft up and go test (-5.95 %), AST (+30.81 %), medio-lateral oscillations in open eyes and dual-task condition (-22.03 % and -10.37 %). Pilates was effective in increasing upper body, lower body, and abdominal muscle strength. No changes on body composition were detected. Results on this investigation indicated also that 12-week of mat Pilates is not sufficient to determine a clinical meaningful improvement on static balance in single and dual-task conditions.

To compare sitting stability between patients with high and low thoracic spinal cord injury (SCI), to determine the factors that can predict sitting stability, and to examine the relationship between sitting stability and functional performance. Cross-sectional assessment was performed on subjects with paraplegia. Rehabilitation hospital affiliated with a medical university. Convenience sample of 30 adults with complete chronic thoracic SCI. Not applicable. Main Outcome Measures: (1) Postural sway during quiet sitting over 30 seconds was recorded as static sitting stability, and composite maximal weight-shift during leaning tasks over 30 seconds was measured as dynamic sitting stability; (2) age, body weight, trunk length, trunk strength, postonset duration, injury level, and presence of spasticity were examined as predictive variables for sitting stability; and (3) the time for completion of upper- and lower-body dressing and undressing and transfer was measured as functional performance. A significant difference in composite maximal weight-shift was found between high and low thoracic SCI subjects (t=2.90, P<.01). Injury level and trunk length were 2 important predictive factors for dynamic sitting stability, and they explained 43.5% of the variance. Only the completion time of upper-body dressing and undressing correlated significantly with static (r=.465, P=.01) and dynamic (r=-.377, P<.05) sitting stability. The subjects with low thoracic SCI showed better dynamic sitting stability than those with high thoracic SCI. Injury level and trunk length, not trunk flexion or extension strength, predicted the outcome of dynamic sitting stability. Measures were not precise enough to predict functional performance from the viewpoint of injury level and sitting stability. The underlying premise that a reduction or increase in trunk strength is indicative of poorer or better sitting stability in SCI individuals is questioned, and implications for problem identification and treatment planning are discussed.

Little is known about the effectiveness of cognitive-behavioral treatment options for patients following lumbar disc surgery. If the knowledge available was supported by an economic evaluation, the information could then be used to make recommendations for the implementation of cognitive-behavioral treatment in the routine of rehabilitation following lumbar disc surgery. To examine the cost-effectiveness of a behavioral-graded activity program, which is an operant treatment, compared to usual care as delivered by a physical therapist for patients following first-time lumbar disc surgery. For the economic evaluation, a societal viewpoint was applied. The primary outcome measures (measured at the 12-month follow-up) were global perceived effect and functional status. To evaluate the economic consequences of the treatments, direct health care and non-health care costs were considered, as well as indirect costs. The clinical outcomes showed no relevant differences between behavioral-graded activity (n = 52) and UC (n = 53). Treatment costs were almost identical in the two intervention groups. The difference in direct health care costs was, although not statistically significant, 264 EURO [95% CI: -3-525] higher in behavioral-graded activity than in usual care per patient-year. It was mainly the excess cost of visiting the physiotherapist in the behavioral-graded activity group that accounted for this difference. The difference in direct non-health care costs, although not statistically significant, was 388 EURO [95% CI: -217; 992] lower in the usual care group due to unpaid help by friends or family. Consequently, although again not statistically significant, the total direct costs in behavioral-graded activity are 639 EURO [95% CI: -91; 1368] higher than in usual care. For the indirect costs, there was a statistically significant difference, behavioral-graded activity being more expensive. The sensitivity analysis showed that these results are fairly robust. This study concludes that there are no differences between the two treatment conditions on any of the clinical outcome measures but that behavioral-graded activity is associated with higher costs. Consequently, there is no reason for the implementation of behavioral-graded activity as the standard treatment for patients following lumbar disc surgery.

Six control subjects and eight subjects with type 1 and type 2 diabetes were studied to understand the relationship between skin temperature, central body temperature, and sweat rate. The results of the experiments show that for all diabetic subjects (both type 1 and type 2) heat tolerance was poor. In fact, with a 30 minute exposure to an environmental temperature of 42°C, even though subjects were at rest, central body temperature increased 1°C more than that of controls. Further, skin temperature also increased. The reason for the increase in skin temperature and central body temperature appeared to be a failure of sweating. Sweating was lower at any skin temperature or at any skin location in diabetic compared with control subjects. Thus both Type 1 and Type 2 diabetic subjects were more susceptible to heat stress. This could have significant implications for heat disorders such as heat stroke for individuals with diabetes.

Four male and 4 female subjects participated in a series of experiments to determine the aerobic capacity of the abdominal muscles and to see if a portable abdominal machine called the 6 Second Abs machine could increase the aerobic endurance and strength of the abdominal muscles. Subjects were trained for 20 minutes per day 3 times per week for 3 weeks. Each training session involved accomplishing 6 second supine abdominal crunches with feet on a wall at a load adjusted to fatigue the subject in 20 minutes or less. When 20 minutes could be accomplished, the load on the abdominal exerciser was increased for the next training day. After 3 weeks of training, there was a 35.8% increase in abdominal strength and an increase in VO2 max of 93%. Over the same period, the work accomplished during a 20-minute session increased by 66.9%. Thus by using a progressive resistance exerciser for abdominal training, a large increase in training of strength and endurance could be accomplished in a short time.

Seven male and 4 female subjects were examined to assess muscle use, while performing standard abdominal crunches lying in the supine position versus abdominal crunches performed in the seated and supine positions using an exercise device called the 6 Second Abs. The results of the experiments showed that much of the work in a supine sit up was due to work against gravity. The addition of resistive bands, when exercising in the supine position, caused an increase in work accomplished during abdominal exercise by at least 15-fold. Further, significant exercise was accomplished when using the machine in the seated position facing forward. More significantly, by rotating the trunk to the seated position, muscle use can be switched from the rectus abdominus, facing forward to the obliques when the trunk is rotated to the side, thereby increasing oblique work 15-fold over standard crunches. In addition to advantages of abdominal exercise in the normal population, this type of exercise is important for people with disabilities, since work may not be possible in a supine position. Abdominal exercise in the seated position with the 6 Second Abs machine appears to control timing better and is more muscle specific than exercise in the supine position.

Respiratory complications, such as pneumonia and atelectasis, are major causes of mortality and inhibit rehabilitation programs in spinal cord injury. Tetraplegic patients cannot cough enough to clear their sputum because of expiratory muscle weakness, mainly of the abdominal muscles. However, tetraplegics are still able to activate some muscles during coughing. Some tetraplegics, even though they cannot contract the abdominal muscles, can cough effectively. It was supposed that some accessory expiratory muscles were activated during coughing in tetraplegics. We, therefore, studied the peak expiratory flow rate, expiratory muscle strength, and the activities of the pectoralis major and latissimus dorsi muscles in 11 complete tetraplegics. Peak expiratory flow rate was measured by spirometry. Expiratory muscles strength was assessed by maximal expiratory mouth pressure; muscle activity was assessed by means of the root mean square voltage obtained by surface electromyography. The results showed that peak expiratory flow rate, maximal expiratory mouth pressure, and root mean square of these two muscles were correlated with neurological level. Peak expiratory flow rate was correlated with peak expiratory flow rate. Peak expiratory flow rate was correlated with the root mean square voltage of the pectoralis major and latissimus dorsi muscles. It was supposed that these two muscles were activated as accessory expiratory muscles and play an important role in expiratory function in tetraplegic patients.

Previous studies on the relationship of age to isometric muscular strength are few, on isometric endurance rare, and on the physiological responses to static effort nonexistent. This investigation assessed the maximal handgrip strength, the duration of a fatiguing handgrip contraction at a tension of 40% of maximal strength and the heart rate and blood pressure during that contraction of 100 men aged from 22 to 62 yr. The subjects of this study were all men employed in a machine shop for a large aircraft corporation. The homogeneity of their occupations may well explain why, unlike previous reports, we found no change in muscular strength or muscular endurance with age. However, although heart rate increased during the contraction in all subjects, the increase in heart rate was greater in younger men. In contrast, while both systolic and diastolic blood pressures increased during the contraction in all subjects, the largest increase in systolic blood pressure was attained by the men in the older decades; there was no difference due to age in the diastolic blood pressures. The implications of these findings are discussed.

Cellular energetics can be studied non-invasively using 31P nuclear magnetic resonance (NMR). Besides the concentration of the major phosphorus-containing metabolites, enzyme-catalysed fluxes and intracellular pH can be obtained from the NMR measurement. Metabolic acidosis in the ischaemic myocardium has been studied in the perfused rat heart. Comparison of the pH, measured from the position of the inorganic phosphate (Pi) resonance, with the pH obtained from the resonance of 2-deoxyglucose 6-phosphate (accumulated after perfusion with 2-deoxyglucose) demonstrates that cytoplasmic pH values are being obtained. The pH changes during ischaemia are quantitatively related to the glycogen leads to lactate conversion. Preperfusion with insulin enhanced the lactate production but resulted in the maintenance of ATP for a longer period during ischaemia, even though acidosis was enhanced. In acute renal acidosis, the decrease in intracellular pH is smaller than might have been expected, as demonstrated in the perfused rat kidney. The importance of acidosis in relation to renal preservation was examined in human kidneys prior to transplantation. 31P NMR studies on human forearm muscle have been done. The pH changes measured during aerobic and anaerobic exercise demonstrate the importance of glycogenolysis in providing energy for ATP production. In a patient with suspected McArdle's syndrome, 31P NMR was used to detect the lack of glycogenolysis since during both aerobic and anaerobic exercise a pH rise was observed together with the rapid breakdown of phosphocreatine.

The purpose of this study was to investigate the relationships between blood lactic acid (LA) accumulation, maximum anaerobic power, glycolytic enzyme activity, and skeletal muscle fibre composition in endurance trained runners. Venous LA was measured in 15 male middle distance (MD) and long distance (LD) runners before and after a 30 second all out ergometer ride. Muscle biopsies of the lateral gastrocnemius muscle were obtained prior to exercise for determination of lactate dehydrogenase (LDH), and phosphofructokinase (PFK) enzyme activities and histochemical classification of fast twitch (FT) and slow twitch (ST) muscle fibres. Significant differences were observed in %FT fibre composition (47.8(MD) and 34.6 (LD), and mean VO2 max values were significantly higher in the LD runners (62.8 (MD) and 68.7 (LD) ml.kg.-1 min.-1). Blood lactate values following maximal treadmill running were significantly higher in the MD group (15.0 mM) when compared with LD runners (11.9 mM). Total anaerobic power output was calculated according to the "Wingate Anaerobic Test" at 51 (MD) and 49 (LD) kpm. kg.-1 min.-1 and mean post-exercise LA values were 8.6 mM (MD) and 8.0 mM (LD). Similar non-significant differences were observed when muscular power was determined via the "Margaria Test" (109.6 (LD) kgm.sec-1). Correlations were determined and the best relationship was between PFK and %FT (R = 0.84). The data suggest that the ergometer test was of insufficient duration, and thus did not result in maximal accumulation of LA and/or metabolically produced LA is removed rapidly in endurance trained muscle. Endurance training in middle and long distance runners fails to produce high value for anaerobic power tests.

Anaerobic threshold (AT) and maximum oxygen uptake (max VO2) were determined in 15 young female cross-country skiers, aged 15--20 years, during incremental bycycle ergometer exercise. Succinate dehydrogenase (SDH), malate dehydrogenase (MDH), citrate synthase (CS) and lactate dehydrogenase (LDH) were analyzed biochemically and percentage of slow twitch fibres (%ST fibres, myosin adenosine triphosphatase staining) histochemically in muscle samples obtained from m. vastus lateralis. Max VO2 correlated significantly with anaerobic threshold in ml x kg-1 x min-1 (mlAT) but when AT was expressed in percent of max VO2 (%AT) the correlation was insignificant. Significant correlations were found between %AT and SDH (r = 0.63) and between mlAT and CS (r = 0.58). Max VO2 showed no significant correlations with the enzymes studied or %ST fibres. The results of the study seem to support the hypothesis that anaerobic threshold is related to oxidative capacity of muscle.

Groups of 50 healthy male controls and 50 subjects suffering from paraplegia (aged 20-65 years) were examined as to the inter-relationships between age, paraplegia and the strength, endurance, blood pressure and heart rate responses to fatiguing isometric exercise. Contractions were maintained in both groups under voluntary effort and through a contraction induced by electrical stimulation in the paraplegic group. All contractions were maintained to fatigue at a tension of 40% of the maximal muscle strength in either the handgrip or quadriceps muscles. Muscle strength of the handgrip was higher in the paraplegic subjects than in the controls, averaging 589 N and 463 N, respectively for the two groups. In contrast, quadriceps leg extension strength averaged 696 N in the controls and 190 N in the paraplegic groups; for both groups, ageing was associated with a reduction in muscle strength. While leg endurance was less in the paraplegic group than the control group, handgrip endurance was similar in the two groups, endurance increasing with ageing in both the controls and paraplegics. Both systolic and diastolic blood pressures increased at rest in paraplegic and control subjects with age. The magnitude of the pressor response to exercise also increased with age. This was true during both voluntary exercise and exercise induced through electrical stimulation in the paraplegic groups. The heart rate response (change in heart rate during exercise) to a fatiguing isometric handgrip contraction decreased by about 50% between the ages of 20 and 60 years in both the controls and paraplegics for isometric handgrip exercise. In contrast, heart rate changed little with age during contractions of the quadriceps muscle in paraplegics which were induced by electrical stimulation.

Impaired mobility is one of the strongest predictors for falls in older people. We hypothesized that exercise as part of a fall prevention program would have positive effects, both short- and long-term, on gait, balance and strength in older people at high risk of falling and with varying levels of cognition, residing in residential care facilities. A secondary hypothesis was that these effects would be associated with a reduced risk of falling. 187 out of all residents living in 9 facilities, > or =65 years of age were at high risk of falling. The facilities were cluster-randomized to fall intervention or usual care. The intervention program comprised: education, environment, individually designed exercise, drug review, post-fall assessments, aids, and hip protectors. Data were adjusted for baseline performance and clustering. At 11 weeks, positive intervention effects were found on independent ambulation (FAC, p=0.026), maximum gait speed (p=0.002), and step height (> or =10 cm, p<0.001), but not significantly on the Berg Balance Scale. At 9 months (long-term outcome), 3 intervention and 15 control residents had lost the ability to walk (p=0.001). Independent ambulation and maximum gait speed were maintained in the intervention group but deteriorated in the control group (p=0.001). Residents with both higher and lower cognition benefited in most outcome measures. No association was found between improved mobility and reduced risk of falling. Exercise, as part of a fall prevention program, appears to preserve the ability to walk, maintain gait speed, ambulate independently, and improve step height. Benefits were found in residents with both lower and higher cognitive impairment, but were not found to be associated with a reduced risk of falling.

The effects of 5 weeks of unilateral lower limb suspension (ULLS) and flywheel resistance exercise (RE) on skeletal muscle protein composition were examined in thirty-one subjects (40 +/- 8y), divided into three groups: ULLS, ULLS+RE, and RE. Pre and post biopsy samples were examined for protein concentration, myosin heavy chain (MHC) and actin concentration. VL protein concentration of the three groups did not change. Soleus protein concentration following ULLS decreased (p<0.05). MHC and actin content of the VL and soleus were unaltered. Muscle mass changed from pre to post: ULLS -11% (VL), -11% (soleus), both p<0.05; ULLS+RE +9%, p<0.05; RE +6%, P<0.05. Therefore, the increase or decrease in VL muscle mass over 5 weeks occurred while maintaining protein, MHC and actin. However, soleus muscle atrophy occurred at the expense of other muscle proteins, since MHC and actin were maintained and protein concentrations decreased.
