| 摘 要： | 通过文献资料调研、现场拍摄法、视频图像解析法等对国内、外优秀女子三级跳远运动员的助跑步长和速度进行了纵向的整体性研究及横向的层次性研究。研究发现,助跑速度是运动成绩提高的源动力;国外优秀运动员水平越高,助跑最后10m的速度与比赛成绩的相关性就越大;最后两步步长随着竞技水平的提高有增加的趋势,并具有明显的个体差异性;在横向上,国外优秀运动员助跑最后两步的速度,随着竞技水平的不断提高而增加,呈加速攻板状态,国内优秀运动员在上板瞬间整体呈减速状态;国外优秀运动员的比赛成绩与助跑最后两步步长呈负相关关系,与最后两步助跑速度呈正相关关系,国内优秀运动员助跑最后两步步长与速度匹配的实效性不如国外优秀运动员。

| Abstract: | This paper carries out vertical overall research and horizontal level study on running approach step length and speed of domestic and foreign excellent women’s triple-jump athletes through using the method of literature review,on-site shooting,and video image analysis.The study found out that running approach speed was the source power to improve athletic performance;the sports level of outstanding foreign athletes is higher,the correlation level between the speed of last ten meter stage of running approach and the match results is greater;the step length of the last two steps has increasing trend along with continuous improvement of competitive level,meanwhile,it has significant individual differences;the speed of the final two steps of running approach of outstanding foreign athletes is increased along with continuous improvement of competitive level in the horizontal point of view,it is basically in speed rhythm characteristics of ’slow to fast’,namely,in acceleration attack board state,in contrast,domestic elite athletes is generally in deceleration state in the moment of boarding,and show the speed rhythm characteristics of ’fast to slow’,the competition results of foreign outstanding athletes are negatively correlated with the step length of the last two steps of running approach,and the matching effectiveness of step length and speed of the final two steps of running approach of domestic elite athletes is not as good as foreign elite athletes. |
