Short-term Closed Comprehensive Intervention on Over-weight Girls' Body Composition, Leptin and Estradiol

Objective: The purpose of this study was to investigate the effect of short-term closed comprehensive intervention on weight losing and sexual development on 10 fat girls in short-term closed training camp and the effect of short-term comprehensive intervention on body composition, insulin, leptin and estradiol of them. Result: the girls after 15 days training had a lower body fat percent, body BMI, plasm leptin, plasm insulin estradiol and a higher lean body mass percent than them before training, but the blood sugar had changed little. Conclusion: (1)the fat girls had a insulin resistance, the short-term comprehensive intervention reduced the plasm insulin, improved the insulin resistance, and played a preventive role on the occurrence of diabetes. (2)the fat girls had a leptin resistance and early sexual development, the short-term comprehensive intervention may reduce body fat effectively, and it also improved the leptin resistance, increased the sensitivity on leptin of hypothalamic, reduced the secretio
