摘要

Purpose: To test whether the moderate intensity aerobic dance is a useful exercise mode for weight loss in obese young-aged women. Method: Thirteen female (age 17.8 ± 1.2 years; initial body fat %=36.0±6.9%; BMI=26.5±5.5Kg/m^2) participated in our 2-month weight-loss program consisting of diet and exercise prescription. To compare the effectiveness of exercise modes, the body composition, heart rate variability (HRV) and oxygen consumption tests were administered before and after training. Pair t-tests were utilized to evaluate data. Result: After training the body mass, VE/VO2, and VE/VCO2 significantly decreased (p＜0.05). The VO2, VCO2 and O2 Pulse significantly increased, while %body fat, waist circumference, maximal heart rate and HRV remained essentially unchanged. The diet intake also had no significant changes before and post training. Conclusion: The results suggest that the cardiovascular fitness changes for overweight female possibly through the combination of improved stroke volumed and peripheral O2 uptake mechanisms. To improve weight-loss efficiency, more restricted diet control program and increasing exercise frequency should be combined.
