棒球挥击速度的研究

The Research On Batting Velooity of Baseball

应用高速动态分析仪对部分运动员挥击速度现状的解析参数进行了研究．得出从启动──中球的挥击时间：斜碰撞时是在棒速下降时进行的．现要求棒的挥击时间在１００ｍｓ以内，投手球飞行至本垒前３．４ｍ左右时棒开始启挥．

Using KODAK high-speed motion analyser system to make the research on batting velocity of baseball,we got the time from the begining of batting ball and found that the velocity of swing of bat had gone down when batter bat ball. Now we require the swing time exceed 0.1" and batter begins to swing baseball bat when ball reaches at 3. 4 meters from home plate.
