摘要

This study was to investigate the effect of weight reduction on body composition and resting metabolic rate in femal adolescent. A 10-week weight reduction program was deviced. Twelve female students (aged 16-18 years) were divided volunteer into three groups including control group (CG), diet group (DG) and exercise and diet group (EDG). DG consumed 1200 kcal/day with no exercise. EDG consumed 1200 kcal daily and 30 mins/day aerobic exercise for 3-5 days per week, 10 weeks. The body composition and resting metabolic rate were measured before and after the program. The results are as follows:1. Body weight: The average weight reduction of DG and EDG were 2.9 kg and 5.3 kg (p＞.05). The changes were significant for both two groups. After investigating the water in the bodies of two groups, there was no obvious difference. It means that the reduction of body weight were not from the change of body water.2. Body fat: Average body fat of the DG decreased 1.06 kg (p＞.05), and it did not reach the significant difference, however, EDG lost 4.58 kg (p＜.05), which fit the obvious standard. The ratial of two groups' body fat reduced 1.06% and 4.1 %, and both of them qualified. It demonstrated that the all achieved the goal.3. Resting metabolic rate: Although the resting metabolic rate for DG and EDG decreased 46 and 23 kcal, there did not significant change. Further exercise really slowed down the falling range of fat-free mass and resting metabolic rate.It is concluded that 10 weeks of diet control and exercise decreased the effect of resting metabolic rate. It is necessary to continue exercising when people on diet successfully achieve the goal. To sum up, successful weight reduction requires to change the mode of behavior to assure their achievement.
