Abstract: Objective To investigate the effect of short-term intensive training on body composition in children with simple obesity. Methods All the obese children were selected from participating in the weight loss summer camp of Zhengzhou Children's Hospital in July 2012 and 2013,including 28 males and 32 females,aged 8 years and 6 months to 14 years old.Weight loss program was including aerobic exercise,proper diet.Aerobic exercise program was designed according to different children of different treatment options,using the principle of gradual and orderly progress,and gradually achieve weight control requirements.The body composition and height,weight,BMI,body water,protein,inorganic salt,fat,body fat percentage,muscle were analyzed in children with simple obesity before and after training.SPSS 16.0 statistical software was used for the above data,paired t-test before and after weight training. Results After 3 weeks of training,weight[(64.97±17.89) kg,BMI (27.42±5.24) kg/m²],fat[(26.68±10.88) kg],body fat percentage[(39.49±9.38%)]were significantly lower than those in before training[weight (68.06 ± 20.19) kg,BMI (29.09±6.41) kg/m²,fat (30.02±12.22) kg,body fat percentage (42.40±8.61)%](P<0.05),while height[(152.64±10.28) cm vs (151.61±10.15) cm],inorganic salts[(2.70±0.66) kg vs (2.61±0.65) kg]were significantly increased (P<0.05),but the water in body[(28.07±6.27) kg vs (27.98±6.72) kg],protein[(7.50±1.68) kg vs (7.45±1.80) kg],muscle[(20.67±5.06) kg vs (20.50±5.44) kg]were no significant changes (P>0.05). Conclusions Short-term intensive training can effectively control the weight through reduced fat in obese children,but is also conducive to the enhancement of children's height and physique enhancement.

摘要： 目的 探讨短期强化训练对单纯性肥胖儿童人体成分改变的影响。方法 选取参加2012、2013年7月郑州市儿童医院减重夏令营的肥胖儿童60例,男28例,女32例,年龄8岁6月～14岁。减重方案包括有氧运动、合理饮食。有氧运动的方案根据不同学生设计不同治疗方案,采用循序渐进的原则,逐渐达到控制体重要求。同时利用人体成分分析仪分别于训练前、训练后对单纯性肥胖儿童进行测量身高、体重、体质指数(body mass index,BMI)、身体水分、蛋白质、无机盐、脂肪、体脂百分比、肌肉。利用SPSS 16.0统计软件对以上数据进行减重训练前后配对t检验。结果 经过3周的减重训练后,体重[(64.97±17.89)kg]、BMI[(27.42±5.24)kg/m²]、脂肪[(26.68±10.88)kg]、体脂百分比[(39.49±9.38)%]较减重训练前[(68.06±20.19)kg、(29.09±6.41)kg/m²、(30.02±12.22)kg、(42.40±8.61)%]均明显降低(P＜0.05),而身高[(152.64±10.28)cm vs (151.61±10.15)cm]、无机盐[(2.70±0.66)kg vs(2.61±0.65)kg]均明显增加(P均＜0.05),但身体水分[(28.07±6.27)kg vs (27.98±6.72)kg]、蛋白质[(7.50±1.68)kg vs(7.45±1.80)kg]、肌肉[(20.67±5.06)kg vs (20.50±5.44)kg]均无明显变化(P＞0.05)。结论 短期强化训练通过减脂作用有效达到控制肥胖儿童的体重,同时还有利于儿童身高的提升和体质增强。
