摘　　要：目的:探讨有氧运动(AE)、抗阻运动(ST)和有氧联合抗阻运动(AE+ST)对肥胖青少年的干预效果,为肥胖青少年制定有个性化的运动处方提供依据。方法:60名男性肥胖青少年随机分为AE组(n=15)、ST组(n=15)、AE+ST组(n=15)和对照组(n=15)。AE组受试者进行8周AE,ST组受试者进行8周ST,AE+ST组受试者进行8周AE+ST。试验前后分别测定受试者体质量、体质量指数(BMI)、体脂百分比(BF%)、脂肪质量(FM)和瘦体质量(LBM),检测血清白细胞介素6(IL-6)、IL-18、肿瘤坏死因子α(TNF-α)和C-反应蛋白(CRP)表达水平,测定最大摄氧量(VO2max)、力竭时间(ET)和最大功率(MP)。结果:试验前4组受试者各指标比较差异均无统计学意义(P>0.05)。与试验前比较,试验后AE组受试者体质量、BMI、FM、BF%和IL-18水平降低(P<0.05或P<0.01),VO2max、ET和MP升高(P<0.01);ST组受试者BF%降低(P<0.05),FFM和TNF-α水平升高(P<0.05或P<0.01);AE+ST组受试者体质量、BMI、FM、BF%和IL-18水平降低(P<0.05或P<0.01),FFM、VO2max、ET和MP升高(P<0.05或P<0.01)。与对照组比较,试验后AE组受试者体质量、BMI、FM、BF%和IL-18水平降低(P<0.05或P<0.01),VO2max、ET和MP升高(P<0.01);ST组受试者FFM和TNF-α水平升高,BF%降低(P<0.05或P<0.01);AE+ST组受试者体质量、BMI、FM、BF%和IL-18水平降低(P<0.05或P<0.01),FFM、VO2max、ET和MP升高(P<0.05或P<0.01)。与AE组比较,试验后AE+ST组受试者IL-18水平降低(P<0.01)。结论:3种运动方式均可改善肥胖青少年身体成分,但只有单纯AE和AE联合ST可明显下调炎症因子水平并提高运动能力,且AE联合ST的效果优于单纯AE。Objective To explore the effects of aerobic exercise（AE）,strength training（ST）and aerobic exercise combined with strength training（AE＋ST）on the obese teenagers,and to provide the evidence for special exercise prescription in the obese teenagers.Methods Sixty obese teenagers were randomly divided into AE group（n=15）,ST group（n=15）,AE＋ST group（n=15）and control group（n=15）.The subjects in AE group performed 8-week AE,and the subjects in ST group did ST,and the subjects in AE＋ST group conducted AE＋ST.The body weights,body mass indexes（BMI）,percentage of body fat（BF%）,fat mass（FM）,lean body mass（LBM）,serum expression levels of interleukin-6（IL-6）,IL-18,tumor necrosis factor-α（TNF-α）,C-reaction protein（CRP）,maximal oxgen uptake（VO2max）,exhaust time（ET）and maximal power（MP）of the subjects were determined before and after the experiment.Results There were no significantly differences of the indexes between the patients in four groups before experiment（P〉0.05）.Compared with before experiment,the body weight,BMI,FM,BF% and IL-18 level of the subjects were reduced（P〈0.05 or P〈0.01）while the VO2 max,ET and MP were elevated（P〈0.01）in AE group;the BF% was decreased（P〈0.05）while the FFM and TNF-αlevel were increased（P〈0.05 or P〈0.01）in ST group;the body weight,BMI,FM,BF%,and IL-18 level were reduced（P〈0.05 or P〈0.01）while the FFM,VO2 max,ET and MP were elevated（P〈0.05 or P〈0.01）in AE＋ST group.Compared with control group,the body weight,BMI,FM,BF% and IL-18 level were reduced（P〈0.05 or P〈0.01）while the VO2 max,ET,and MP were elevated（P〈0.01）in AE group;the BF% was decreased（P〈0.05）while the FFM and TNF-αlevel were increased（P〈0.05 or P〈0.01）in ST group;the body weight,BMI,FM,BF% and IL-18 level were reduced（P〈0.05 or P〈0.01）while the FFM,VO2 max,ET and MP were elevated（P〈0.05 or P〈0.01）in AE＋ST group.Compared with AE group,the IL-18 level was reduced in
