摘　　要：目的：通过观察16周单纯有氧减肥运动处方对12-15岁肥胖初中生身体成分及血浆瘦素的影响,探讨运动减肥的可能机制,为肥胖初中生减肥运动处方的制定提供实验依据.方法：以23名12～15岁体重指数≥25 kg/m2的肥胖初中生志愿者为研究对象,按制定的有氧运动处方训练16周（每周运动3次,有氧运动强度为50％～ 70％最大心率,每次50min）.训练前后分别测体重（W）、体重指数（BMI）、体脂含量（FM）、体脂百分比（％F）;同时测定血浆TG、TCH、HDL-C、LDL-C的含量和血浆瘦素水平.结果：16周单纯有氧练习减肥运动处方锻炼后,初中生W、BMI、FM、％F较训练前明显下降,P＜0.05;血浆TG、TCH和LDL-C的含量明显降低,P＜0.05,HDL-C略有升高,无统计学意义;血浆瘦素水平明显下降,P ＜0.05,血浆瘦素水平与W、BMI、FM、F％、TG、TCH和LDL-C的呈正相关（P＜0.05）,与HDL-C呈负相关.结论：长期有氧运动处方锻炼对肥胖初中生的体重和身体成分有很好的改善作用,降低体内瘦素水平,对血脂代谢异常具有很好的调节作用,同时,血浆瘦素水平与体脂含量呈正相关.Objective：The study investigated the effect of 16-week aerobic exerciseprescription for weight deduction onbody compositions and theblood plasma level of leptin in obese junior middle school students, so as to offer a newexperimental basistheory to aerobic exercise prescription for obese school students. Methods ：23 obese school students whose body mass indexes are beyond 25kg/m^2 were investigated. They exercised for 16 weeks according to exercise prescription for weight deduction （three times per week,50min aerobic exercise at 50% -70% HRmax intensity） . Before and after 16-week ex-ercise, the obese students were tested weight （ W）, body mass index （ BMI ）, fat mass （ FM）, percent body fat （ F% ） and the plasma level of leptin and also tested TG ,TCH,HDL-C, LDL-C levels in plasma were also tested using automatic bio- chemical analyzer. Results：After 16-week aerobic exercise prescription training for weight deduction,the weight, BMI, FM and F% of obese school studentswere decreased（ P 〈 0.05 ） ;the plasma level of TG, TCH, LDL-C were decreased obvi- ously （ P 〈 0.05 ） ; and the plasma level of leptin was also decreased obviously （ P 〈 0.05 ） . At the same time, the changes of the W, BMI, FM and F% were significantly and positive correlatively with the change of leptin. Conclusions： Long-term aerobic exercise according to exercise prescription for weight deduction has a positive function to body composition and thelevel of serum leptin.
