摘要
目的:建立肥胖男童最大脂肪氧化强度(FATmax)运动减重模式,探讨10周FATmax运动干预肥胖男童的效果。方法:36名9~10岁肥胖男童随机对半分为干预组和对照组。经递增负荷实验确定FATmax强度研制处方,进行10周运动干预,实验前后测量BMI、身体成分、腰围、臀围、大腿围、肺活量、最大摄氧量、握力、1 min仰卧起坐、屈臂支撑时间、立位体前屈、50m跑、立定跳远、简单反应时等进行对比。结果:肥胖男童FATmax强度为44±13%VO_2max,对应的心率为140±6b/min,速度为4.0±0.69km/h;干预组干预后体重、BMI、体脂%、腹部脂肪、腰围等显著降低;肺活量、最大摄氧量、躯干肌耐力及柔韧性等显著性提升,对照组各指标无明显变化。结论:持续10周规律的FATmax强度运动可有效实现9~10岁肥胖男童安全减重,并对心肺机能和肌肉耐力有显著的改善作用。
Objective:To study the effects of exercise training at the maximal fat oxidation(FATmax)intensity on body composition,cardiovascular fitness,and exercise ability in 9-to-10-year-old boys with obesity.Methods:Thirty-six(36)boys with obesity,aged 9~10 years,were randomly divided into the FATmax or non-exercise control group.FATmax was identified in a graded exercise test,and the intensity was applied to design the individualised exercise program for each subject.FATmax group took part in 10 weeks of exercise training.Body composition,cardiovascular fitness,and exercise ability were measured before and after experiments.Results:At the FATmax intensity,the trained boys had an average heart rate at 140±6 bpm and running speed at 4.0±0.7km/h.FATmax group increased body height while decreased body mass,body mass index,and abdominal fat mass(P〈0.05 for all variables).VO_2 max,lung capacity,heart function index,1 min sit-and-up,and body flexibility were improved significantly(P〈0.05 for all variables).No significant improvement was found in the control group after the experimental period.Conclusion:10 weeks of FATmax exercise training is safe and effective to treat obese children.
