The aim of our study was to determine whether resistance exercise-induced elevations in endogenous hormones enhance muscle strength and hypertrophy with training. Twelve healthy young men (21.8 +/- 1.2 yr, body mass index = 23.1 +/- 0.6 kg/m(2)) trained their elbow flexors independently for 15 wk on separate days and under different hormonal milieu. In one training condition, participants perfo...

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...

Body weight is influenced by both food intake and energy expenditure. Acylated ghrelin enhances appetite, and its circulating level is suppressed by growth hormone. Data on the acylated ghrelin responses to exercise of different intensities in obese individuals are currently not available. This study examined the effects of an intermittent exercise protocol on acylated ghrelin levels and hunger...

The present study was carried out for 7 days on four adult low-lander single-humped camels to know the effectof endurance load exercise physiological, biochemical, hormonal, and inflammatory cytokines at high altitude.A significant 1.5 3 fold increase observed in physiological responses, viz. respiration heart rate onthe 1st 7th day after exercise. Further, serum triglycerides levels were signi...

treatments for breast cancer such as chemotherapy or hormone therapy can increase osteoporosis. it seems that exercise training can improve bone mineral density. therefore, the aim of this study was to investigate the effect of combined exercise training on bone mineral density (bmd) in postmenopausal women with breast cancer. 29 postmenopausal women with breast cancer (58.27 ± 6.31 years) who ...

TO THE EDITOR: The authors present an interesting analysis of the effect of moderate-intensity exercise-induced catecholamines on cognition speed (4). They summarize that moderate and catecholamine threshold (CT) exercise facilitates the speed of cognition and attribute it to activation of adrenergic neurons in the vagal/ NTS/LC pathway (4). Catecholamine release is also regulated by stress (1)...

The manuscript "Plasma Somatomedin-C in 8- to 10-Year-Old Swimmers" by Denison and Ben-Ezra published in the first issue of Pediatric Exercise Science in 1989 was among the first to address the relationship between growth, the growth hormone (GH)/Insulin like growth factor-1 (IGF-1) axis, and exercise. Since their pioneering article, this topic has become of great interest to pediatricians and ...

We analyzed adaptation mechanisms regulating systemic inflammatory response of the stressed body by using an experimental challenge of repeated exercise bouts and accompanying muscle inflammation. Eight untrained men bicycled at 90 W for 90 min, 3 days in a row. Exercise induced peripheral neutrophilia with a leftward shift of neutrophil nucleus and neutrophil priming for oxidative activity det...
