Abstract
Purpose: exercise and nutrition have been considered as optimal interventions for obesity treatment worldwide. Therefore, effect of concurrent training and caffeine supplementation on Body Composition and hemodynamic parameters in overweight and obese girls were examined in this study. Methods: In a Semi experimental and double-blind design, Twenty healthy, overweight and obese girls (age: 23.85 ± 0.82, BMI: 28.54 ± 0.71, weight: 73.70 ± 1.74, height: 1.61 ± 0.01) were randomly divided two homogeneous groups (concurrent training + caffeine supplementation; concurrent training + Placebo. Anthropometric and hemodynamic parameters were measured in the fasting state before and after the 30 days of concurrent training and caffeine and placebo supplementation (5 mg/kg body weight/day). Data was analyzed using Mann–Whitney U test and Wilcoxon tests. Results: There was a significant change in weight, body mass index and WHR in both experimental groups after four weeks. The systolic blood pressure and resting heart rate and rate-pressure product (RPP) were decreased in experimental groups after exercise intervention while no significant difference was found for all Variables in the two experimental groups. Conclusions: According to the results in this study, concurrent training (aerobics-resistance) and caffeine supplementation can be effective measures to control blood pressure and cardiovascular disease, also improves anthropometric characteristics of the body.
