| 摘要: | The purpose of this study was to examine the effects of exercise training and diet control on serum leptin levels and obesity indexes. Twenty-five overweight high school female students (aged 17.23 0.74, height 161.32 4.80 cm, weight 68.20 7.11 kg, body mass index [BMI] 26.16 2.04 kg/m2) were enrolled in either 8 weeks of aerobic exercise training with dietary intake controls (group ED with 1405.50 123.36 kcal/day, n=13) or exercise training alone (group E, n=12). The training program consisted of jogging for 30 minutes, 3 times/per with exercise intensity at 50-70% heart rate reserve. The results showed that group ED had significant decrease in body weight ( 5.92±2.82 kg, p＜.05 ) and body fat percentage (2.78±1.23%, p＜.05), group E had significant decrease in body weight (3.18±1.57 kg, p＜.05) and body fat percentage (l.52±0.58%, p＜.05), and leptin levels had significant changes (p＜.05), respectively, on days 1, 28, and 56 for group ED (12.36±3.29 ng/ml, 6.12±2.86 ng/ml, and 8.79 3.49 ng/ml) and group E (10.26±3.32 ng/ml, 7.39±4.11 ng/ml, and 7.58±3.50 ng/ml). These results indicated that eight weeks of regular exercise, with or without diet controls, caused significant decreases in the body weights, BMI, waist/hip ratios, body fat percentage and serum leptin levels of overweight female high school students. |
