出　　处：《田径》2009年第7期64-64,共1页Track and Field

摘　　要：跨越水池的生物力学分析 当身体重心超过支撑腿时，伸脚触及并用钉鞋扒紧横木的前缘。当身体重心进一步向前移动时，用力向前而不是向上跳离开横木。Clearing the water jump： biomechanical aspects When the center of gravity passes over the supporting leg, the extended foot touches an grips the front edge of the barrier with the spikes. As the center of gravity moves further forward, a powerful take-off jump forwards, rather than upwards, follows. The trail leg is brought forward slowly as in the triple jump.

关 键 词：生物力学分析 身体重心 三级跳远 起跨腿 摆动腿 用力
