    ABSTRACT: Background: The aim of the study was to evaluate overweight, obesity and the level of physical activity in the study group of 100 cadets of the Air Force Military Academy in Deblin (WSOSP). Material and Methods: Evaluation of overweight and obesity was based on body mass index (BMI) and body fat content. An accelerometer AiperMotion 500 (TM) was used to measure the level of physical activity. There were marked such parameters as the average daily energy consumption, the average distance covered during the day and the whole week and the indicator of physical activity level (PAL). Results: Based on BMI indicators, 71.3% of the cadets had normal body weight, 25.3% were overweight and 3.4% were obese. Assessment of nutritional status showed significant differences between the 1st and 2nd vs. the 4th and 5th years of study. Normal BMI values showed 88% of the 1st and 2nd year students, while of the 4th and 5th years - only 48.6% (p < 0.05). Based on the body fat content, obesity was found only in a group of older students (16.2%) and overweight was 10 times higher in the 4th and 5th years (21.6%) in comparison to younger students (2%). The average distance covered during the day or during the whole week was significantly higher in the 1st and 2nd year students. Conclusions: It is necessary to implement appropriate measures in the field of nutrition and physical activity to prevent the development of excessive body weight during studies among the military cadets of the Air Force Military Academy in Deblin.

    ABSTRACT: Introduction: An important problem for pilots is visual disturbances occurring under +Gz acceleration. Assessment of the degree of intensification of these disturbances is generally accepted as the acceleration tolerance level (ATL) criterion determined in human centrifuges. The aim of this research was to evaluate the visual-motor responses of pilots during rapidly increasing acceleration contained in cyclic intervals of +6 Gz to the maximum ATL. Methods: The study involved 40 male pilots ages 32-41 yr. The task was a quick and faultless response to the light stimuli presented on a light bar during exposure to acceleration until reaching the ATL. Simple response time (SRT) measurements were performed using a visual-motor analysis system throughout the exposures which allowed assessment of a pilot's ATL. Results: There were 29 pilots who tolerated the initial phase of interval acceleration and achieved +6 Gz, completing the test at ATL. Relative to the control measurements, the obtained results indicate a significant effect of the applied acceleration on response time. SRT during +6 Gz exposure was not significantly longer compared with the reaction time between each of the intervals. SRT and erroneous reactions indicated no statistically significant differences between the "lower" and "higher" ATL groups. Conclusion: SRT measurements over the +6-Gz exposure intervals did not vary between "lower" and "higher" ATL groups and, therefore, are not useful in predicting pilot performance. The gradual exposure to the maximum value of +6 Gz with exposure to the first three intervals on the +6-Gz plateau effectively differentiated pilots.

    ABSTRACT: The experimental data related to Valsalva manouvers and short term voluntary apnea, available in the literature, suggest that the cerebral blood flow increase and reduction of the peripheral one may be expected if the specific AFTE based respiratory training is performed. The authors had verified this hypothesis by studying the relations between EEG measured subject relaxation combined with voluntary apnea by multimodal brain imaging technique (EEG mapping, Neuroscan and fMRI) in a group of healthy volunteers. The SPM analysis of respiratory related changes in cortical and subcortical BOLD signal has partially confirmed the hypothesis. The mechanism of this effect is probably based on the simultaneous blood pressure increase and total peripheral resistance increase. However the question is still open for further experimental verification if AFTE can be treated as the tool which can increase pilot/astronaut situation awareness in the extreme environment typical for aerospace operations where highly variable accelerations due to liftoff, rapid maneuvers, and e.g. vibrations can be expected in the critical phases of the mission. AFTE refers to NASA AMES patented technology -Autogenic Feedback Training Exercise

    ABSTRACT: Introduction. Hard work in farming may lead to lumbar spinal stenosis, and consequently, to pain. The pain and neurological disorders may lead to disability and postural disorders. Objective. The aim of the presented study was to analyse postural stability and its correlation with functional disability of patients with lumbar spinal stenosis living in rural areas. Materials and methods. The study population consisted of 30 rural patients with lumbar spinal stenosis; mean age: 51.40 (±12.92); mean BMI: 28.60 (±3.77). The control group consisted of 30 rural inhabitants without spinal disorders. Postural stability was tested on the Biodex Balance System. The patients were also evaluated according to the ODI, the Rolland- Morris disability questionnaire, and VAS. Results. The mean results of the patients studied were as follows: 49.37 (±17.39) according to ODI, 15 (±6.19) according to the Rolland-Morris disability scale, and pain intensity of 7 (±1.93) according to the VAS. The following statistically significant differences were found: the mean balance index result was 1.8 (±1.88) and 0.64 (±0.41) in the control group. The mean centre of mass deviation in the A/P plane was 1.39 (±1.88) and 0.46 (±0.41) in the control group. The mean centre of mass deviation in the M/L plane was 0.8 (±0.51) and 0.32 (±0.22) in the control group. The balance in the studied population correlated significantly with the Rolland-Morris disability questionnaire and the VAS. Conclusions: 1) Serious disability was found in rural patients with spinal stenosis. There was a statistically significant correlation between the disability and postural stability disorders. 2) Most of the patients (84%) were overweight. 3) Postural stability disorders were statistically significant for both the stability index and the A/P plane deviation.

    ABSTRACT: Back pain in Air Force fast jet pilots has been studied by several air forces and found to be relatively common. The objective of the study was to determine the prevalence and degree of the pain intensity in the cervical, thoracic and lumbar spine, subjective risk factors and their effect on the pilots' performance while flying high maneuver aircrafts and the consequences for cognitive deficiencies. The study was designed as a retrospective, anonymous questionnaire survey, collecting data on the age, aircraft type, flying hours, pain characteristics, physical activity, etc. The study was participated by 94 pilots aged 28-45 years (mean age: 35.9±3.3 years), actively flying fast jet aircrafts Su-22, Mig-29 and F-16. The estimates regarding the level of the subjective back pain were established using visual analogue scales (VAS). The values of the Cochran and Cox T-test for heterogeneous variances are as follows: for the total number of flying hours: F = 2.53, p = 0.0145, for the pilot's age: F = 3.15, p = 0.003, and for the BMI factor F = 2.73, p = 0.008. Our questionnaire survey showed a significant problem regarding spinal conditions in high performance aircraft pilots. The determination of the risk factors may lead to solving this problem and help eliminate the effect of the unfavorable environment on piloting jet aircrafts. Experiencing back pain during the flight might influence the mission performance and flight safety. The costs of pilots education are enormous and inability to fly, or even disability, leads to considerable economic loss. More research on specific prevention strategies is warranted in order to improve the in-flight working environment of fighter pilots.

    ABSTRACT: Surgical treatment of obesity is currently the only effective treatment option for patients with excess body weight, especially morbid obesity and diseases caused by it. There are no studies evaluating the knowledge of surgeons in the field of bariatric surgery. To assess the knowledge of surgeons regarding bariatric surgery. An anonymous questionnaire was conducted among 143 surgeons in 2010-2011 during local educational conferences. The survey consisted of 10 questions dedicated to the fundamental problems of the surgical treatment of obesity. Theoretical and practical knowledge connected to the so-called "epidemiological awareness" in the surgical treatment of obesity was possessed by 25% of the respondents. Knowledge of surgical techniques is known to most surgeons. Reducing the "oncological risk" after bariatric surgery is known to only 27% of surgeons. Almost 80% of surgeons indicated a necessity of their further education regarding the surgical treatment of obesity. Knowledge of Polish general surgeons in the surgical treatment of obesity is not high, with a high number of surgeons who possess knowledge of the operating technique, whereas only a quarter have a basic knowledge of the indication for surgical treatment. Most surgeons who participated in our study are awaiting educational programmes focused on this issue.
