Grip size of a tennis racquet has been reported to influence performance, but clear evidence of a correlation has yet to be established.
Hitting force during a soft tennis forehand stroke correlates with grip size.
Controlled clinical study.
A total of 40 healthy volunteers (20 men and 20 women) with a mean age of 21.9 years were enrolled. Of the 40 participants, 20 were experienced soft tennis players (10 men and 10 women) and 20 were nonexperienced soft tennis players (10 men and 10 women). Based on racquets with 5 different grip sizes, the hitting force during a soft tennis forehand stroke was measured with a handheld dynamometer. Correlations between 4 factors (sex, experience, grip and pinch strengths, and middle finger length) and hitting force were evaluated with each grip size. Measurements for each factor were repeated, and a 2-way analysis of variance was performed on the obtained data.
The hitting force was greater for male players than for female players and greater for experienced players than for nonexperienced players (P < .01). Men with large grip and pinch strengths demonstrated an increased hitting force with an increase in grip size. Men who had a long middle finger also demonstrated increased hitting force when grip size increased (P < .05).
The hypothesis proved accurate for experienced men who had a large grip strength, a large pinch strength, and a long middle finger.
Large-grip-sized racquets may result in better forehand stroke performance when used by experienced male soft tennis players with a large grip strength, a large pinch strength, and a long middle finger.
网球拍的握把大小据报道会影响表现，但尚未有明确的相关证据。
软式网球正手击球的击球力与握把大小相关。
对照临床试验。
共纳入 40 名健康志愿者（20 名男性和 20 名女性），平均年龄为 21.9 岁。40 名参与者中，20 名是有经验的软式网球运动员（10 名男性和 10 名女性），20 名是无经验的软式网球运动员（10 名男性和 10 名女性）。根据 5 种不同握把尺寸的球拍，使用手持测力计测量软式网球正手击球时的击球力。评估 4 个因素（性别、经验、握把和捏力强度以及中指长度）与击球力之间的相关性，每个握把尺寸都进行评估。每个因素的测量都重复进行，对获得的数据进行双因素方差分析。
男性运动员的击球力大于女性运动员，有经验的运动员大于无经验的运动员（P <.01）。握把和捏力强度大的男性运动员随着握把尺寸的增加而增加击球力。中指较长的男性运动员随着握把尺寸的增加击球力也增加（P <.05）。
该假设对于握把力量大、捏力强度大且中指较长的有经验男性运动员是准确的。
对于握把力量大、捏力强度大且中指较长的有经验的男性软式网球运动员来说，使用大握把尺寸的球拍可能会提高正手击球的表现。
