为提高我国短跑运动技术水平提供理论支持,以第16届亚运会100 m跑男运动员为研究对象,通过对54人次的起跑后蹬时间-压力曲线结构进行对比分析,得出了双波峰与三波峰两种曲线类型。研究结果表明：双波峰结构优势在于双脚后蹬时间短和双脚后蹬力量更大,是一种更为合理的起跑后蹬时间-压力曲线结构。在起跑训练中,我们应重点加强双脚后蹬用力协同性的训练。如果劳义在起跑训练中将其起跑后蹬时间-压力曲线由三波峰结构转变为双波峰结构,将使他的100 m成绩由10.24 s提高到10.21s的水平。

To provide theoretical support for the sprint technique of China＇s sprinters,with the 100-metre male sprinters in the 16th Asian Games as subjects,this article compared and analyzed the structure of the pre-start back kick time-pressure curve of 54 person-time and obtained two curve types i.e.double-peak curve and three-peak curve.The result of the research proved that the advantage of double-peak curve was shorter back kick time with stronger force,which was a more reasonable structure of pre-start back kick time and pressure curve.In the training for the start of sprint,we should emphasize the coordination of back kick force.If the three-peak curve can be changed into double-peak curve in the training process,Lao Yi＇s score for 100-metre sprint can be improved from 10.24s to 10.21s.
