We aimed to investigate the effects of eight weeks of selected aerobic training on serum leptin levels, anthropometric indices and maximal oxygen consumption (VO2max) in obese men. Methods: Twenty healthy elderly men were selected by convenience sampling method and were randomly assigned to control (n = 10) and experimental (n = 10) groups. The program training included 45 minutes per session, three times per week for eight weeks of participation in aerobic exercise classes with 55-60% HRR. Pre- and post-aerobic exercise, serum leptin levels, anthropometric indices and VO2max were evaluated. To make intra and intergroup comparisons, t-test for dependent and independent samples were used. For all statistical comparisons, the level of significance was set at P < 0.05. Results: Eight weeks of aerobic exercise led to a significant increase of Vo2max (P = 0.01). The amount of leptin (P = 0.007), weight (P = 0.002), BMI (P = 0.003), body fat percentage (P = 0.002) and WHR (P = 0.013) in sedentary obese men in the experimental group significantly reduced. The variations of weight, BMI, BFP, WHR and Vo2max in the two groups had differences. Conclusions: The results of this study showed that the selected aerobic training had a favorable influence on improvement of serum leptin levels and VO2max in obese men. M3 10.21859/joe-05014 ER -
