摘　　要：对短跑运动员脚踝刚性传导下肢力量进行实验对比研究,探讨脚踝刚性对短跑运动员百米成绩、立定跳远、原地快速下蹲跳、起跑前5步平均触地时间、起跑前5步平均躯干前倾角度和起跑前5步平均落地支撑胫骨角度变化等方面的影响。结果表明,缩短触地时间,脚踝刚性的增强会减少力的损耗,这对提高短跑运动员下肢力量的传导有十分重要的作用。This experimental comparative study delves into the examination of ankle rigidity and its effect on the transmission of lower limb force among short-distance sprinters.The study scrutinizes the influence of ankle rigidity on various aspects,including 100-meter sprint performance,standing long jump,stationary rapid squat jump,average ground contact time for the initial 5 steps of the start,average forward trunk lean angle for the first 5 steps of the start,and average landing support tibial angle changes.The findings suggest that reinforcing ankle rigidity diminishes power loss,resulting in a reduction of ground contact timean essential factor in enhancing the transmission of lower limb force for short-distance sprinters.
