摘　　要：目的:研究单次高强度抗阻训练和单次高强度间歇有氧运动之后12h及24h基础代谢率的变化。方法:将66例受试者随机分为抗阻训练组22例、有氧训练组22例、对照组22例,所有组员训练前、训练后12h和训练后24h后均采用间接测热法,通过K4b2型心肺功能测定仪进行基础代谢率(BMR)测定。抗阻训练运动方式为肩负杠铃垂直下蹲,强度为80%一次最大重复负荷(1RM),每组10次,共4组;有氧训练运动方式为功率自行车,强度为90%最大摄氧量(VO2max),共4组训练,每组以5min训练、5min休息的间歇训练模式进行。结果:训练前三组间的基础代谢率均无明显差异(P>0.05);训练后12h基础代谢率,抗阻训练组和有氧训练组较对照组明显升高(P<0.05),且抗阻训练组增加更显著(P<0.05);训练后三组间24h基础代谢率无明显差异(P>0.05)。结论:单次高强度抗阻训练和单次高强度间歇有氧运动均能够明显提高运动之后12h内的能量消耗,且与单次高强度间歇有氧运动相比,单次高强度抗阻训练对基础代谢率的提高更显著。Objective： To investigate the changes of basal metabolic rate （BMR） 12h and 24h after a single bout high-in- tensity resistance training and high-intensity interval aerobic exercise, respectively. Method： Sixty-six adults were divided into resistance training group （n=22）, aerobic exercise group （n=22） and control group （n=22）. All subjects＇ BMR was assessed by portable gas metabolic analyzer （K4b2, COSMED） before and 12h, 24h after training period. Resistance training group performed 4 sets of exercises, at 80% of one-repetition maximum （1-RM） for 10 repetitions. Aerobic exercise group did 4 sections of exercises at 90% of VO2max, and each section lasted 5min with 5min interval. Result： There was no significant difference （P〉 0.05） in BMR in three groups before training. Compared with control group, the BMR of resistance training group and aerobic exercise group was significantly higher （P〈 0.05） 12h after training, and resistance training group improved more than that of aerobic exercise group. There was no significant difference among 3 groups in BMR 24h after training （P 〉 0.05）. Conclusion： A single bout high-intensity resistance training and high-intensity interval aerobic exercise can sig- nificantly improve the energy expenditure 12h after training, and resistance training improves more than that of aerobic exercise.
