Effects of Resistance Exercises on Serum Leptin and Some Inflammatory Markers in Obese Males

The main purpose of the present study was to assess the effects of resistance exercise (RE) regimens on leptin concentrations and on risk factors for coronary heart disease in obese sedentary males. Thirty subjects were recruited into this study, 20 control subjects and 20 individuals for resistance exercise. Subjects ranged in age from 20 to 40 years. The subjects reported in the laboratory on the morning after a 12-h fast. Blood (10 ml) was obtained from an antecubital vein, with the subject in an upright position, before exercise and at 10 h after six weeks of resistance training. In conclusion, after resistance exercise, leptin and CRP showed significant differences when compared to resting values. In addition, these values were related to each other after exercise. Other cytokines and different types of subjects should be included in further studies.
