摘　　要：对56名肥胖儿童（年龄7-11岁,31名男生,25名女生）进行4个月的运动训练,运动前后测量各项指标,研究其运动后体成分变化的个体差异与饮食和体力活动等变化的关系.结果表明：实验对象体脂百分比（F%）下降显著,而体脂含量（FM）、去脂体重（FFM）上升,然而个体之间变化存在很大的差异.多元回归模型显示,运动后体成分改善与较高的运动出勤率、性别、较低的能量摄入和较多的体力活动密切相关.运动干预后,年龄、体力活动程度、饮食和基线的F%等变量的变化可以解释肥胖儿童运动后F%变化的26%.To study the relationship between the interindividual variations in the response of body composition to physical training with variations in diet and physical activity. 56 obese children aged 7-11 （31 boys, 25 girls） underwent an 24-week experiment. Results. The percentage of body fat decreased significantly,and body mass, fat-free mass increased significantly, while there was a good deal of indi- vidual variability. Multiple regression models indicates that in general, more frequent attendance,gender,lower energy intake, and more vigorous activity are associated with healthier body-composition changes with physical training. In obese children, age, vigorous activity, diet, and baseline percentage of body fat together accounts for 26% of the variance in the change in percentage body fat with physical training.
