Effect of Exercise Therapy on the Body Composition and Blood Components of Obese Men

[Purpose] The purpose of this study was to examine the effects of an eight-week exercise program on body composition, blood lipids, and hormone levels of 16 obese adult males. [Subjects and Methods] After an experimental group (n=8) and a control group (n=8) were organized, subject were examined: then, the experimental group performed endurance exercises for 8 weeks. At the end of the eight weeks, the two groups were examined again for weight, % body fat, and body fat mass via a bioelectrical impedance analysis (BIA). A blood sample was collected the day before the exercise program. Right after the exercise program, 5 ml of blood was collected and then centrifuged for 10 min at 3000 rpm. The centrifuged samples were stored at -73°C and sent to Green Cross for analysis; TC, TG, leptin, and insulin were analyzed. [Results] The experimental group showed a statistically significant decrease in % body fat and body fat mass as well as significant reductions in TC and TG and leptin concentrations. There was also a decrease in the exercise group's insulin concentration but is was not significant. [Conclusion] Eight weeks of exercise therapy increased energy consumption resulting in favorable changes in the body composition, blood lipid metabolism, and hormone levels in obese adult males.
