短期高强度间歇运动训练对青年男性运动耐量的影响

The effect of hort-term high intensity intermittent exercise training on exercise capacity of young males

目的:探讨短期的高强度间歇运动训练对平素缺乏运动的青年男性运动耐量的影响。方法:符合入选条件的19名青年男性志愿者被随机分为高强度间歇运动训练组(HIT组)、中等强度持续运动训练组(MCT组)和无运动训练的对照组(CON)。HIT组参加持续2周,每周3次,共6次的高强度间歇运动平板训练。MCT组参加2周,每周3次,共6次的中等强度持续运动平板训练。训练前后3天各进行一次极量运动试验,比较前后运动耐量的变化。结果:HIT组训练后完成运动试验的运动总时间增加,运动耐量由运动前的(14.1±1.7)METs增加至运动训练后的(15.0±1.3)METs(P<0.05);训练后与CON组比较差异具显著性(P<0.05)。CMT组训练后完成运动试验的运动总时间增加(P<0.05),但运动耐量增加无显著性。结论:短期的高强度间歇运动训练能有效提高平素缺乏运动的青年男性运动耐量,其效果优于中等强度持续运动训练。

Objective：To examine the effect of short-term high intensity intermittent exercise training,compared with moderate intensity continuous exercise training,on exercise capacity of physically inactive young males.Method：Nineteen physically inactive young male volunteers were randomized to three groups：high intensity intermittent training（HIT,n=6）,moderate intensity continuous training（MCT,n=7） and no training control（CON,n=6） group.The training was performed within 2 weeks with 1—2d rest between sessions,6 times at all.The maximal exercise treadmill test was carried out 3d before and after training.The exercise capacity（METs） and the total exercise time（s） were measured by exercise test and analyzed.Result：In HIT group,the exercise capacity increased significantly from（14.1±1.7） to（15.0±1.3）METs,and the total exercise time prolonged（P〈0.05）.There was significant difference between HIT and CON groups（P〈0.05）.In MCT group,the total exercise time prolonged,but there was no effect on exercise capacity.Conclusion：Short term high intensity intermittent training can increase the exercise capacity of physical inactivity young males,the effect is superior to moderate intensity continuous exercise
