Modern tennis forehand grip style and ball contact points have evolved to enhance power and topspin. Different grip styles and ball contacts are recommended; however, little data are available to support one over another. Through a quantitative experimental study, we sought to determine which grip style and ball contact point produced the greatest forces at static contact. The continental, eastern, and semi-western forehand groundstroke grips of 100 volunteers were evaluated. Participants stood in three defined positions and applied maximum force against a dynamometer with each grip style. The associations of force produced at contact with the grip style, age, sex, tennis experience, and handedness were evaluated using univariate and multivariate linear mixed-effects regression models separately for early, mid, and late contact, including a random effect for each participant. Force production was significantly greater with eastern grip at early, mid, and late contact than with the other two grips (p < 0.001). Force was greater at early contact with semi-western grip than with continental. Force was also significantly greater for men at early, mid, and late contact (p < 0.001). Participants using an eastern grip were able to generate more force compared to those using a continental or semi-western grip, regardless of the ball contact point. Tennis players currently using other forehand grip styles who want to maximize power production may consider transitioning to an eastern forehand grip. The results of this study may improve tennis instruction and training for beginning and novice players who lack force generation.
现代网球正手击球握拍方式和击球点已经演变，以增强力量和上旋。推荐了不同的握拍方式和击球点；然而，几乎没有数据能支持一种方式优于另一种。通过一项定量实验研究，我们试图确定哪种握拍方式和击球点在静态接触时能产生最大的力量。对100名志愿者的大陆式、东方式和半西方式正手击球握拍进行了评估。参与者站在三个规定位置，用每种握拍方式对测力计施加最大力量。分别针对早期、中期和晚期接触，使用单变量和多变量线性混合效应回归模型评估接触时产生的力量与握拍方式、年龄、性别、网球经验和惯用手之间的关联，包括每个参与者的随机效应。在早期、中期和晚期接触时，东方式握拍产生的力量显著大于其他两种握拍方式（p < 0.001）。在早期接触时，半西方式握拍产生的力量大于大陆式握拍。在早期、中期和晚期接触时，男性产生的力量也显著更大（p < 0.001）。无论击球点如何，使用东方式握拍的参与者比使用大陆式或半西方式握拍的参与者能产生更大的力量。目前使用其他正手击球握拍方式且想最大化力量输出的网球运动员可能会考虑过渡到东方式正手击球握拍。这项研究的结果可能会改善针对缺乏力量生成能力的初学者和新手球员的网球教学与训练。
