Abstract

|
|
The purpose of this study was to investigate the effect of aerobic training on abdominal fat and leptin hormone. Subjects were composed of fourteen obese adolescents. Aerobic training was performed 40 minutes per day, 4dyas per week at 53.7±4.92% HRmax during 1-24 weeks and at 64.4±4.72% HRmax during 13-24 weeks. The items for abdominal fat volume were measured subcutaneous fat volume (SFV), visceral fat volume (VFV), VFV/ SFV by computed tomography. Paired t-test was used to evaluate the difference of baseline and after 24 weeks aerobics training. The 0.05 level of significance was as critical level for the study.
The results of this study are as follow;
1. Body composition, %body fat and fat mass decreased significantly after 24 weeks aerobics training.
2. LDL-C, TG, leptin decreased significantly and HDL-C increased significantly after 24 weeks aerobics training.
3. VFV, SFV and VFV/SFV decreased significantly after 24 weeks aerobics training.
In conclusion, that on Body composition, HDL-C increased significantly and leptin, subcutaneous fat, visceral fat, s/v decreased in aerobic training. So it could be thought that long-term aerobic training improve serum lipids and body composition for obesity treatment.
