本文是首次对起跑后加速跑阶段的三维蹬地力进行测试和分析,并较全面地揭示出加速跑阶段蹬地力的诸多方面的特征及其变化趋势。上述特征及变化趋势,适应于加速跑阶段的任务与技术要求。另外关于加速跑第一步即存在前支撑阻力、横向蹬地力的产生原因及控制方法等具有理论和实际运用的意义。
This article is the first time to test and analyze the three-dimensional pedaling force during the acceleration phase after starting and fully reveals the features and trends of pedaling force during acceleration phase. The above characteristics and trends, to adapt to the task of running phase and technical requirements. In addition to the first step on the acceleration that there is the former support resistance, lateral pedaling force causes and control methods have theoretical and practical significance.
