摘　　要：目的了解自行车运动员在200 m计时赛中的加速位置、速度分配以及运动员的个人特点,确定最佳比赛方案。方法以上海自行车队4名优秀男子短距离自行车运动员为研究对象,使用摄像机和SRM训练系统,对运动员场地200 m计时赛进行实时监测,对运动员的加速位置、速度分配、个人特点进行分析比较。结果测试结果都显示,运动员在进入200 m计时区域之前一段的速度要明显高于达到终点前一段的速度。摄像解析和SRM训练系统推测的200 m计时赛理想成绩均比实际成绩要好,但是两种方法推测的最佳成绩、最佳加速点有微小的差异。结论 (1)自行车运动员在200 m计时赛中加速过早,消耗了体力,会最终影响比赛成绩。(2)根据运动员个人特点,选择合适的加速方案,可以明显提高200 m计时赛成绩。(3)从确定最佳加速点位置角度考虑,摄像解析结果相对而言较SRM训练系统(Professional版)精确。SRM训练系统可以检测运动过程中的功率变化,反映运动员在训练和比赛中的实时情况,对指导训练有非常重要的作用。Purpose The aim of this study was to find out the accelerate position,velocity assign and individual characteristic of flying 200 m time trial in track cycling in order to confirm the best compete project.Methods Taking 4 elite male track short-distance cyclists as the subjects,the results of the flying 200 m time trial in the track were tested and analyzed after their training by SRM training system and vidicon.Results The research work has brought about a discovery of the speed of the area before start-point was faster than the area before end-point in flying 200m by monitoring with SRM training system and vidicon.Perfect performance of flying 200 m inferred from monitoring of SRM training system and analysis of vidicon was better than the performance indeed training.However,the best accelerating point and performance inferred had certain of difference between SRM training system and vidicon.Conclusion.（1）The athletes brought the accelerating point forward in flying 200 m time trial result in athletes wasted sinew before they arrived end-point.（2） Appropriate scheme to accelerate in flying 200 m should be chosen according to athlete＇s individual characteristic so as to improve athlete＇s complete achievement.（3） In the view of confirmation of the best accelerating point,the results by vidicon analysis was more accurate than by SRM training system（Professional）.SRM training system was mainly applied to measure power variation during track cycling and could be used to monitor immediate conditions during competition or training,Therefore,SRM training system was important to scientific training.
