This study examined the effects of prior upper body exercise on subsequent high-intensity cycling exercise tolerance and associated changes in neuromuscular function and perceptual responses. Eight men performed three fixed work-rate (85% peak power) cycling tests: 1) to the limit of tolerance (CYC); 2) to the limit of tolerance after prior high-intensity arm-cranking exercise (ARM-CYC); and 3)...

The human body is endowed with varied forms of social significance, and it is this which sociology has addressed by asking questions such as: Towhat degree do individuals have control over their own bodies? Using familiar examples from everyday life, such as diet and exercise regimes,personal hygiene, dress, displays of emotion, and control over bodilyfunctions. This research investigates the b...

BACKGROUND Despite growing interest in the relationship between exercise and short-term neural plasticity, the effects of exercise on motor cortical (M1) excitability are not well studied. Acute, lower-limb aerobic exercise may potentially modulate M1 excitability in working muscles, but the effects on muscles not involved in the exercise are unknown. Here we examined the excitability changes i...

The purpose of this investigation was to examine the effects of moderate hypohydration (HY) on skeletal muscle glycogen resynthesis after exhaustive exercise. On two occasions, eight males completed 2 h of intermittent cycle ergometer exercise (4 bouts of 17 min at 60% and 3 min at 80% of maximal O2 consumption/10 min rest) to reduce muscle glycogen concentrations (control values 711 +/- 41 mum...

STUDY OBJECTIVE Exercise has the potential to improve the ability of a patient with cystic fibrosis (CF) to cope with the physical demands of everyday life, and may improve prognosis. The purpose of this study was to compare the effects of a home-based, semi-supervised, upper-body strength-training regimen with a similarly structured aerobic training regimen. DESIGN Data were collected during...

purpose the purpose of the present study was to evaluate effects of regular practice of sun salutation on muscle strength, general body endurance and body composition. methods subjects (49 male and 30 female) performed 24 cycles of sun salutation, 6 days a week for 24 weeks. upper body muscle strength was determined by 1 repetition maximum (1rm) for bench press and shoulder press technique. bac...

purpose the aim of this study was to assess the effects of ramadan fasting on several biochemical and anthropometric parameters in physically active men by comparing fasters and nonfasters before, during, and after ramadan. methods eighteen physically active men (10 fasters and 8 nonfasters) participated in this study. subjects visited the laboratory for a total of four sessions on the followin...

purpose to evaluate the effect of ramadan fasting on body water status markers of rugby players at basal condition and following a simulation of rugby sevens match. methods twelve recreational rugby sevens players played three matches: one day before ramadan (before ramadan), at the end of the first week of ramadan (beg-r) and at the end of ramadan (end-r). before and immediately after each mat...

OBJECTIVES The health benefits of resistance training for women have been well documented. However, few investigations have been reported on the immune responses to resistance training among young people. To determine the effects of resistance training on natural killer cell activity (NKCA) in young people, a study was conducted among healthy female university students. METHODS The study was ...

The aim of this study was to examine acute hormonal responses after different sequences of an upper-body resistance-exercise session. Twenty men completed 2 sessions (3 sets; 70% 1-repetition maximum; 2 min passive rest between sets) of the same exercises in opposite sequences (larger to smaller vs. smaller to larger muscle-group exercises). Total testosterone (TT), free testosterone (FT), test...
