Cause Analysis of the Factors Influencing Vertical Take-off Speed Conversion Rate of in High Jump and Countermeasures

Abstract: By way of consulting the relevant documents and watching games on video, it was noted that Chinese athletes’ take-off speed is generally slower than that of their foreign rival athletes, and a still greater gap lies between Chinese athletes and their foreign rivlals in the vertical speed conversion rate after takeoff， which to some degree retards their improving of the high jump performance. Run-up speed plays an important role in high jump. The capacity of rapid energy supply of the ATP-CP system and the peak work capacity(PWC) of the muscle-nerve system are also the inner factors that play a part in the conversion rate of the vertical speed, yet both can be made available by training. In order to improve high jump performance, efforts should be made to improve our abilities in these respects.
