目的了解8周抗阻训练对肥胖儿童身体成分、血脂及血清瘦素的影响,为改善肥胖儿童的健康水平以及寻求更好的减肥方法提供理论依据。方法根据WHO推荐的身高标准体重法,选取晋中市18名肥胖儿童(男、女各9名)进行8周抗阻训练,然后对运动前后身体成分[体重、体质量指数(BMI)、肌肉量及躯干肌肉量、身体脂肪量、身体各部位脂肪量及身体脂肪比率]、血脂[总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白(LDL)、高密度脂蛋白(HDL)]及血清瘦素水平进行比较。结果肥胖儿童抗阻训练后血清瘦素、TG、LDL水平均下降(P值均<0.05),HDL水平上升(P<0.01);男性肥胖儿童抗阻训练后体重,BMI,身体脂肪量,左右上肢及躯干脂肪量均下降(P值均<0.05),肌肉量及躯干肌肉量均增加(P值均<0.05);女性肥胖儿童抗阻训练后BMI,身体脂肪量,右下肢、右上肢及躯干脂肪量均下降(P值均<0.05),肌肉量及躯干肌肉量增加(P值均<0.01)。结论 8周抗阻训练可以降低肥胖儿童BMI、身体脂肪量和血清瘦素水平,增加肌肉质量,改善血脂紊乱。
Objective To understand the effects of 8-week resistance training on body composition, serum lipids and serum leptin levels in obese children and to provide theoretical basis for improving the health of obese children and finding better ways to lose weight. Methods Eighty obese children (9 males and 9 females) in Jinzhong city were selected for resistance training for 8 weeks according to WHO recommended height standard weight method. The body composition [body mass, body mass index (BMI), muscle mass and Trunk muscle mass, body fat mass, body fat mass and body fat ratio], blood lipid [TC, TG, LDL, HDL] And serum leptin levels were compared. Results The levels of serum leptin, TG and LDL in obese children decreased (all P <0.05) and HDL increased (P <0.01) after obstructive training. The body weight, BMI, (P <0.05). The muscle mass and trunk muscle mass of obese children increased (P <0.05). The obese children with BMI, body fat mass, right lower extremity, right upper extremity, Trunk fat mass decreased (P <0.05), muscle mass and trunk muscle increased (P <0.01). Conclusion Anti-resistance training for 8 weeks can reduce BMI, body fat mass and serum leptin level in obese children, increase muscle mass and improve blood lipid disorder.
