The purpose of this study is to understand the effects of exercise, combined with dietary control on body composition and health-related physical fitness of obese children (weight-for-length index, WLI ± 1.25). The health-related physical fitness items include 800-m run (cardiorespiratory fitness), sit-ups (muscular fitness), sit and reach (flexibility), percentage of body fat (body composition) and BMI. Ten children (6 boys and 4 girls), 10.9 ± 1.1years of age, 146.90 ± 8.14 cm in height, and 56.16± 7.44 kg in weight, were included in this study. Subjects were given dietary control guidelines before the experiment, and were asked to record and change in dietary habits everyday during the experiment. Meanwhile, subjects exercised 3 times a week, 50 min. each. The study lasted for 12 weeks. The blood biochemical readings like TC (total cholesterol), TG (triglycerides), HDL (high-density lipoprotein), LDL (low-density lipoprotein), and together with the health-related physical fitness items and body composition variables of the subjects were recorded both before and after the experimental period. Here are the results: l.The average height of the subjects increased significantly (p-value<0.05). The average weight dropped by 1 kg but was notsi gnificant. 2.In the body composition, the average percentage of body fat dropped significantly and the average net weight increased significantly. 3.In the health-related physical fitness, significant progress were observed in every item. 4.In the blood biochemical readings, none of them changed significantly. But the HDL readings of the subjects were all below the normal level both before and after experiment.
