Abstract
The aim of this study was to investigate the effect of endurance, resistance and concurrent training on plasma leptin levels of male students. For this purpose, 48 male university students (mean age 21.45 years) participated in this study. Subjects were randomly assigned to three exercise groups: endurance group (n=12), resistance group (n=12) and concurrent group (n=12) and a control group (n=12). Their height, weight, fat percentage, BMI and VO2max were determined. The endurance group received endurance training for 8 weeks, 3 sessions per week with an intensity of 75-85% maximal heart rate. Also, in resistance training group, 100% power of subjects was determined. Then, during exercise sessions, a percentage of maximum power was prescribed for them. Concurrent group received both endurance and resistance training programs in one day. In order to compare pretest and posttest results, paired t test and ANOVA was used. The results showed that all three methods of endurance, resistance and concurrent training significantly decreased plasma leptin levels (P=0.982). There was no significant difference in the effects of endurance, resistance and concurrent training on plasma leptin changes. It can be concluded that regular physical activity (any type of endurance, resistance or concurrent training with a negative energy balance) can decrease leptin levels.
