Abstract

The present study aimed at investigating serum leptin levels of elite young male athletes who have been regularly exercising for a long period of time and males who do not exercise. The study included 24 trained young male athletes and 22 healthy sedentary male subjects. Athletes who participated in the study were from different sports branches and have been regularly exercising for at least 2 years. Serum leptin levels were determined by RIA. VO2max levels were identified during maximal exercise. Lactic acid levels were identified one minute before and one minute after exercise from the fingertip by Pro-lactate kit. As a result of the tests, although BMI values of trained young male athletes and healthy males were close to each other, leptin levels were significantly lower (p<0.01), VO2max values were significantly higher (p<0.01) and test periods were significantly longer (p<0.001) in the former.  In conclusion, regular exercise, by reducing body fat percentage, suppresses serum leptin levels.
