The relation of leg, shoulder, and grip strength to ball speed in the tennis serve was investigated. For 15 collegiate male tennis players, leg and shoulder strength were measured using a Lido Active isokinetic dynamometer, grip strength with a handgrip dynamometer, and ball speed with a radar gun. Regression analysis showed no significant (p<.05) relationship among the strength variables and ball speed. Results were explained in terms of strength not being the only factor involved in producing ball speed during the tennis serve.
研究了网球发球时腿部、肩部和握力与球速之间的关系。对15名大学男子网球运动员进行了测试，使用Lido主动等速测力计测量腿部和肩部力量，用握力计测量握力，用雷达测速仪测量球速。回归分析表明，力量变量与球速之间不存在显著（p<.05）关系。研究结果表明，力量并非网球发球时产生球速的唯一因素。
