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 time—an essential factor in enhancing the transmission of lower limb force for short-distance sprinters.
