争先赛是奥运会女子场地自行车项目。争先赛资格赛 2 0 0m计时赛是场地自行车速度负荷强度极高的项目。行进间 2 0 0m计时赛的弯道骑行技术是影响专项速度能力的决定性因素。而且 ,也是全程技术动作过程中最复杂、掌握和控制难度较高的技术环节。运动生物力学是科学监控和诊断该项目在高速骑行状态下技术动作的有效方法手段。通过研究发现在弯道骑行过程中存在的问题 ,为提高专项技术训练的质量和效果提供可靠依据。 The first race is the Olympic Games women’s field bike project. Race for the first qualifying match 2 0 0m The time trial is a very high speed bike load. The curve riding technique of the 200-meter time trial in the march is the decisive factor affecting the special speed ability. Moreover, it is also the most complicated technical process in the whole process of operation, and it is difficult to master and control the technical process. Sports biomechanics is an effective means of scientifically monitoring and diagnosing the technical action of this project at high speed riding conditions. Through the research, we found the problems existing in the curve riding and provide a reliable basis for improving the quality and effect of special technical training.
