This study aimed to examine the effect of different methods of active recovery (AR) after high-intensity exercise on exercise performance, determined with the Yo-Yo Intermittent Recovery Test level 2 (Yo-Yo IR2) in soccer referees. Using a crossover design, fourteen male soccer referees completed three trials. After resting for 10 min, participants ran approximately 495 meters (m) at 80% of max...

The purpose of this investigation was to determine the effect of intermittent sub-maximal exercise on percent body fat (%BF) estimated by leg-to-leg bioelectrical impedance analysis (LBIA) in children. Fifty-nine children (29 girls; 30 boys) mean age 9.0 ± 1.3 years participated in this study. LBIA measured %BF values were obtained immediately before and within five minutes after completing an ...

Bright light can phase shift human circadian rhythms, and recent studies have suggested that exercise can also produce phase shifts in humans. However, few studies have examined the phase-shifting effects of intermittent bright light, exercise, or the combination. This simulated night work field study included eight consecutive night shifts followed by daytime sleep/dark periods (delayed 9 h fr...

The aim of this study is to investigate the effects of intermittent ladder-climbing exercise training on mitochondrial biogenesis and ER stress of the cardiac muscle in high fat diet-induced obese middle-aged rats. We induced obesity over 6 weeks of period in 40 male Sprague-Dawley rats around 50 weeks old, and were randomly divided into four experimental groups: chow, HFD, exercise+HFD, and ex...

Arginine supplementation has been shown to induce endothelium-dependent vasodilation and enhance exercise performance via increasing nitric oxide (NO) production in patients with various cardiovascular diseases. The purpose of this study was to determine the effect of short-term arginine supplementation on vasodilation and performance in intermittent anaerobic exercise in well-trained male athl...
