在越野跑和跑道跑中峰值冲击加速度的差异
Various running surfaces and their firmness may affect the likelihood of overuse injuries on the lower extremity. The more firm a surface, the greater the impact acceleration that a runner feels upon landing. Therefore, the purpose of this study is to determine whether there are differences between impact accelerations on different trail running surfaces. 参赛者将在泥地上跑步, 碎石和铺砌小径, with accelerometers attached to different parts of the body to measure these impact accelerations. 我们假设较软的表面会降低撞击加速度, 哪些可以减少下肢损伤的可能性.
