Purpose: Resistance training (RT) improves an array of treatment-related adverse effects in men with prostate cancer, however, the minimal dosage required is unknown. We systematically reviewed the RT effects in prostate cancer patients to determine the minimal dosage regarding the exercise components (type, duration, volume, and intensity) on bod...

Objectives/background The prevalence of obstructive sleep apnea (OSA) in people over 70 years can reach up to 95%. Aerobic or combined exercise programs have been shown to impact positively on OSA severity. Resistance training changes leg fluid retention. We hypothesized that through this mechanism it may have an impact on the OSA severity in older...

Background Muscle strength imbalance assessment (e.g., hamstring-to-quadriceps ratio, H:Q) using traditional peak torque isokinetic measurements has been shown to be a weak risk factor predictor of future lower-limb injuries (e.g., hamstring strain and anterior cruciate ligament tear). In soccer, power-related tasks are commonplace and injuries are...

Purpose Strength training is performed using multi-joint (MJ) or single-joint (SJ) exercises; however, it is not clear whether different time of recovery is necessary between the two types of exercise. The aim of the present study was to compare the time course of recovery of indirect markers of exercise-induced muscle damage (EIMD) in the elbow fl...

Match-induced fatigue of knee muscle strength and agonist-antagonist strength-ratios may affect both performance and risk of injury in soccer players. Once explosive tasks are imperative in soccer as well as hamstring strain injuries occur during high-velocity moments, rapid force capacity of this muscle group is especially important. This study ev...

• Heat Shock Response (HSR) is similar in healthy middle-aged and elderly people, but is blunted in aged individuals with T2DM. • Visceral Adipose Tissue (VAT) is increased with age, and the increased VAT is correlated with a lower HSR. • Resistance training (RT) is an efficient intervention to restore the HSR and reduce inflammation in aged indi...
Article
Isokinetic hamstring to quadriceps ratios are frequently used to assess knee muscle strength imbalances and risk of injuries/re-injuries. The use of peak torque (PT) or total work (TW) to estimate joint stability may lead to different results because of the differences between these two neuromuscular variables. Thus, the current study aimed to comp...

Background Obstructive sleep apnea (OSA) occurs due to sleep-induced upper airway muscle relaxation resulting in increased pharyngeal collapsibility. Clinical trials have shown a favorable effect of exercise training on OSA severity in middle-aged adults. Aging is characterized by motor-unit loss. Force training may affect the whole body muscle ton...

Introduction Among the mechanisms causing hypertension in obstructive sleep apnea (OSA) patients, the roles of hypoxia and of arousals, leading to intermittent oxidative stress and repeated elevations of blood pressure, have been difficult to disentangle. The apnea–hypopnea index (AHI) reflects the number of arousals. The minimum arterial oxygen sa...

Question (1)
Question
Hi RG fellows,
I'm looking for further information regarding the classic fail-safe N method (i.e., to calculate the minimum number of undetected negative studies that would be needed to change the conclusions of a meta-analysis) for network meta-analysis. The application of this method in meta-analysis is usual but I didn't find further information for network meta-analysis... Is this possible? If yes, which package or software is recommended?
Thanks in advance.

The present study compared the effects of 12 weeks of muscle power training performing one or three sets on muscle quality assessed by echo intensity (MQEI) and index (MQindex), muscle power-related outcomes, and functional capacity in older women. Participants were randomly assigned into two groups: 1SET (n = 13) and 3SET (n = 13). Lower limb muscle power and vertical jump height were measured during a countermovement jump, maximal rate of torque development (MRTD), and root mean square (RMS) of electromyography signals and rate of rise (RER) of quadriceps maximal electromyography activation during unilateral knee extension at 0–50 and 0–200 ms, MQEI, MQindex (absolute muscle power/MQEI, and MRTD/MQEI) and functionally in both groups using timed-up-and-go were evaluated before and after training.

The aim of this study was to compare the effects of 12 weeks of muscle power training using one- and three-sets on neuromuscular adaptations in elderly women. Twenty six healthy elderly women were randomly assigned into two groups: one-set (n = 13) and three-sets (n = 13). Maximal dynamic and isometric strength, rapid force assessed as absolute and normalized rate of force development (RTD) and contractile impulse during unilateral leg knee extension at 0–50 and 0–200 ms, overall quadriceps muscle thickness, muscle power during a countermovement jump (CMJ), and functional performance using time-up-and-go and the timed stair climb tests were evaluated before and after training. After 12 weeks, one-set and three-sets groups exhibited significant (p ≤ 0.05) and comparable increases in dynamic and isometric strength, absolute RTD and contractile impulse at 0–50 and at 0–200 ms and in the performance of both functional tests
