Background and Objectives: Strenuous exercises have been shown to induce inflammation. However, consumption of products rich in antioxidants such as vitamin C may enhance this effect. The purpose of this study was to assess effects of vitamin C supplementation on C-reactive protein, lactate and blood pressure following resistance exercise in overweight men. Materials and Methods: In a randomiz...

The present study examined the influence of specific inspiratory muscle training (IMT) upon recovery time during repetitive sprint activity, as well as the physiological and perceptual responses to fixed intensity shuttle running. Using a double-blind placebo-controlled design, 24 male repetitive sprint athletes were assigned randomly to either an IMT (n = 12) or placebo (n = 12) group. The sel...

Dysfunction of the muscles of ambulation contributes to exercise intolerance in chronic obstructive pulmonary disease (COPD). Men with COPD have high prevalence of low testosterone levels, which may contribute to muscle weakness. We determined effects of testosterone supplementation (100 mg of testosterone enanthate injected weekly) with or without resistance training (45 minutes three times we...

background: physical exercise and herbal treatment with antioxidant property induce a favorable effect on glucose metabolism in diabetic patients. the aim of the present study was to investigate the effects of resistance training combined with green tea extract consumption on blood glucose and lipid profile in diabetic rats. forty male wistar diabetic rats aged 5 months and weights 290 ± 20 wer...

We evaluated the effects of specific inspiratory muscle training on simulated time-trial performance in trained cyclists. Using a double-blind, placebo-controlled design, 16 male cyclists (VO2max = 64 +/- 2 ml x kg(-1) x min(-1); mean +/- s(x)) were assigned at random to either an experimental (pressure-threshold inspiratory muscle training) or sham-training control (placebo) group. Pulmonary f...
