目的 比较高强度间歇运动(HIIT)和中等强度持续运动(MICT)对超重成年人心肺适能和身体成分的影响。方法 通过电话、现场招募等方式选取2022年5-8月北京市某社区64名无规律运动习惯的超重男性青年,按照随机数字表法将其分为HIIT组、MICT组和对照组(C组),12周干预前后分别利用递增负荷试验测定最大摄氧量(VO2max),双能X线吸收仪测量身体成分。结果 试验后,HIIT组和MICT组VO2max均升高(P<0.05),MICT组全身脂肪含量、体脂百分比、android区域脂肪含量与百分比下降(P<0.05),去脂体重增加(P<0.05),而HIIT组身体成分的变化均无统计学差异(P>0.05);C组所有参数的变化均无统计学差异。结论 超重男性青年采用不同运动方式进行体力活动时,HIIT在提升心肺适能方面具有时效性,MICT则是改善身体成分的主要手段。
Abstract
Objective To compare the effects of high intensity interval training (HIIT) and moderate intensity continuous training (MICT) on cardiopulmonary fitness and body composition in obese male youth. Methods Sixty-four overweight young men with irregular exercise habits in a community of Beijing were selected by telephone or on-site recruitment from May to August in 2022, and were randomly divided into HIIT group, MICT group and control group (C group) according to the random number table method. The maximum oxygen uptake (VO2max) was measured by graded exercise test and body composition was measured by dual energy X-ray absorptiometry before and after 12-week intervention. Results After the experiment, VO2max increased in both HIIT and MICT groups (P<0.05), the total body fat mass, percentage of body fat, and fat mass and percentage of android area decreased, while free fat mass increased in MICT group (P<0.05), but there was no significant change in body composition in HIIT group (P>0.05). There was no significant change of all parameters in C group (P>0.05). Conclusions HIIT is time-effective in improving cardiopulmonary fitness, and MICT is the main means to improve body composition in overweight young men who use different physical activities.
