关于200米弯道跑风速对运动成绩影响的研究

我国根据国际《田径竞赛规则》规定,破全国记录的200米跑和200米跨栏跑,“从进入直道开始计10秒”,“在顺风时所创记录,凡平均风速超过每秒2米者,不予承认,”那么,200米跑与200米跨栏跑在进入直道前,风向、风速对运动成绩的影响如何呢?从大量的竞赛会中的实际观察和初步实验结果表明,200米跑与200米跨栏跑在弯道跑时,风向与风速对弯道跑的影响较大,忽略不计,会影响运动成绩的真实性。

STUDY OF THE EFFECT OF WIND SPEED ON THE CURVE IN THE RESULTS OF A 200 METRE RACE

Aoconding to tht Jnternatisnal Rulos for The compeition of Tack and Fteld,it is stipulateil the tedonds will not be admi tteil in the 200 matre race and the 200 metres hurdliny whon the average favaur- able wina sptolreconcl th 10 sei immeediately after the sprintrs run onto the straight exceeds 2 metre:/tec. On the basis of the reult:of a great number of actual inve taga- tion anol initial exptpiments,it is thwyht that if the wind:peece of the curvo is rgnored it will greally effeet the accuracy of tfe re- ults in the 200 melre race anol the 200 metre hurolling.
