摘　　要：目的:评定相同强度不同运动量非对称负重对人体下肢爆发力产生的影响。方法:采用随机交互设计,12名健康男性受试者分别完成4次单侧负重往返跑:优势侧20m×5、非优势侧20m×5、优势侧20m×10和非优势侧20m×10,分别在运动后即刻和运动后20min进行爆发力测试,并记录RR间期。结果:与安静状态相比,运动后HR、EPOC和TRIMP值均显著增加(P<0.01),优势侧和非优势20m×5以及20m×10之间不存在显著差异(P>0.05),但20m×10的EPOC和TRIMP值显著大于20m×5。与安静值相比,20m×5和20m×10优势侧和非优势侧运动后即刻整体表现下肢爆发力的H指标呈下降趋势,但20m×5和20m×10优势侧和非优势侧之间不存在显著差异(P>0.05);负荷量增加后,整体上各CMJ指标变化幅度较小;在20min恢复期,大部分指标均恢复到安静状态,而V指标整体上呈增加趋势。结论:在次最大强度、非对称负重运动时,下肢的优势侧不影响运动后即刻下肢爆发力的变化幅度,存在交互效应,负荷量增加,下肢爆发力受到损害程度相对较小;休息20min后大部分指标基本上恢复到安静状态。Objective:To test how the asymmetric load influencing the explosive power of different legs during different distances at same intensity shuttle run.Method:12subjects finish4time shuttle runs with single leg bear load who are health man by randomized crossover design,and undertake the shuttle runs of and20m×10,then test the explosive power immediately and after20min and the RR period is recorded simultaneously.Results:HR,EPOC and TRIMP increased significantly after exercises(P<0.01),there is no different from two legs(P>0.05),but the EPOC and TRIMP value of the20m×10is clearly bigger than that of20m×5so that with the load increased,CMJ has no significant changing,and the V has the trend of increasing.Conclusion:When undertaking exercises of submaximal intensity and asymmetric load,the advantage leg has an interactive effect with no influence to the explosive power;when the load increasing,the explosive power has a certain little lost,and recovers back to the stable situation after20min resting.
