Does regular aerobic training affect basal leptin level (difference between male and female)?

There is discrepancy about the effects of regular exercise training on basal leptin level and most of the existing data have been collected from obese/thin subjects. In this study, the effects of one year aerobic exercise was investigated in normal weight untrained healthy volunteer male and female subjects. The sample included 60 non-athletes, male and female university students. First, all samples were randomly divided into four groups. The practice program including selected aerobic exercises and volleyball drills with specific intensity was applied. The blood samples of subjects were taken once 24 h before the first section of the exercise program and 24 h after the last section of the exercise program. Resting plasma leptin level was determined using ELISA method in pre and posttest and in paired sample T test, whereas one way and two way (factorial) ANOVA was used to analyze the data. Studies show that basal plasma leptin levels in healthy young non-athlete individuals in response to regular exercise in the long term did not fluctuate. Aerobic exercise for one year showed no significant effect on plasma leptin levels (that is about the role of fat tissue as the most significant source of leptin), and it seems that it occurs because fat tissue in subjects did not change.
