PURPOSE Recent studies have shown that low-intensity resistance training with vascular occlusion (kaatsu training) induces muscle hypertrophy. A local hypoxic environment facilitates muscle hypertrophy during kaatsu training. We postulated that muscle hypertrophy can be more efficiently induced by placing the entire body in a hypoxic environment to induce muscle hypoxia followed by resistance t...

The purpose of this study was to investigate the effect of attentional distraction on field running distance and activity intensity during an exercise session in normal-weight and overweight youngsters and to investigate potential mediators. Fifty-three 12-14 yr-old boys participated twice in a 12-min running test and a 20-min exercise session, once with attentional distraction (by listerning t...

Background & objectives: Diabetes mellitus, as a metabolic disease, is associated with impaired insulin resistance index and cardiovascular risk factors. The purpose of this study was to investigate the effect of a concurrent exercise and Ginger supplementation on cardiorespiratory endurance, body composition, and insulin resistance index in obese women with type 2 diabetes. Methods: 60 women ...

Group exercise training programs were introduced as a strategy for improving health and fitness and potentially reducing dropout rates. This study examined the psychophysiological responses to group exercise training sessions. Twenty-seven adults completed two group exercise training sessions of moderate and vigorous exercise intensities in a random and counterbalanced order. The %HRR and the e...

Effects of intensive exercise on hypothalamus-pituitary-testis (HPT) axis remain controversial. Our aim was to determine the effects of intensive, long-term treadmill running on reproductive hormones, HPT axis, and semen quality. A total of 286 subjects were randomly assigned to moderate-intensity exercise (approximately 60% maximal oxygen uptake (VO(2max)); group 1, n=143) and high-intensity e...

Inflammatory markers such as C-reactive protein (CRP), fibrinogen, and white-blood-cell (WBC) count are strongly associated with cardiovascular disease. The authors' purpose was to compare the inflammatory response to a single aerobic-exercise session between individuals of high and moderate fitness. Ten apparently healthy highly fit and 11 moderately fit men expended 500 kcal at 70% of VO2peak...

objective: exercise activity could be an amendment to polycystic ovary syndrome (pcos). however the acute and chronic effects of various exercise intensities on serum leptin levels are ambiguous. this study investigates the acute and chronic responses of various intensities of exercise on serum leptin levels and weights of female rats with pcos. methods: in this semi-empirical study, 80 adult w...

This study was designed to assess the effects of moderate- and high-volume aerobic training on the time domain and on spectral and fractal heart rate (HR) variability indexes. Sedentary subjects were randomized into groups with moderate-volume training (n = 20), high-volume training (n = 20), and controls (n = 15). The training period was 8 wk, including 6 sessions/wk at an intensity of 70-80% ...
