摘　　要： 为了探索影响中跑运动员个体间跑步经济性（running economy,RE）差异的动力学因素,根据VO2max相对值及800m运动成绩,最终确定7人为研究对象（年龄（21.43±0.53）岁;身高（172.8±3.79）cm;体重（63.66±3.82）kg;训练年限（4.57±0.98）年;RE（35.65±2.58）mL·kg-1·min-1）。研究结果发现,RE分别与力的峰值、力的波动范围及冲量相关性都不显著。研究结果表明,垂直方向、前后方向和内外方向的地面反作用力以及跑步支撑阶段冲量,并不是造成中跑运动员RE差异的原因,但是,RE较差的中跑运动员表现出在垂直方向冲量较大的趋势,RE的差异可能是人体下肢肌肉做功的差异造成的。 In order to explore kinetic factors that affect differences in running economy （RE） between individual runners,the authors ultimately selected 7 runners （at the age of （21.43±0.53）,the height of （172.8±3.79） cm,the weight of （63.66±3.82） kg,the trained years of （4.57±0.98）,and the RE of （35.65±2.58） mL· kg-1· min-1） as research subjects according to their relative values of VO2 max and performances in the 800m run,and revealed that the correlations between RE and force peak value,force fluctuation range and impulse were all not significant,which indicated that ground reaction forces in the vertical,longitudinal and transversal directions and impulse at the running support stage were not causes for differences in RE between medium distance runners,however,medium distance runners with a poor RE shown a greater impulse in the vertical direction,and differences in RE may caused by work done by lower limb muscles of the human body.
