网球拍弦磅数变化对优秀网球职业运动员底线击球效果的研究

Research on the Change of Tennis Rackets and Tennis Strings Pounds on the Bottom-line Batting Effect of Professional Athletes

为研究优秀的网球职业运动员是否对球拍拍弦磅数变化有更好的区分能力以及拍弦磅数变化是否会影响到击球效果,本研究使用网球发球机发球,让18名优秀的网球职业运动员参加一个用不同拍弦磅数球拍的（从47磅~64磅）击球测试。从实验结果来看,61%测试者不能准确的区分6磅的拍弦磅数变化,击球后球飞行的平均速度是117 km/h,击球平均速度与落点失误数都与球拍拍弦磅数不存在显著性差异。研究结果表明,优秀网球职业运动员对网球拍弦磅数变化的分辨能力与敏感度较低;优秀的网球职业运动员击球的落点与球拍磅数不存在显著性相关;在底线击球中优秀的网球职业运动员对使用不同磅数的球拍有着很强的适应能力与控制能力。

To study whether the elite professional athletes have better distinguishing ability in the change of pat strings and number of pound and whether the changes will affect the patting effect,the study used the serve machine to serve and 18 elite tennis players took a batting test with different pounds of racket（from 47 pounds to 64 pounds）.The results show that 61% participants can not accurately distinguish the change by 6 pounds.The flight speed of the ball after hitting is 117 km/h.There is no significant difference between the average batting speed,times of the failure of droppoint and the pound of rackets.In the bottom-line batting,elite tennis professional athletes have strong adaptability and control ability in using rackets with different pounds.
