The purpose of this study was to investigate the relationship of flexibility, power, and strength to club head speed (CHS) in male golfers. Fifteen golfers (mean age +/- SD: 34.3 +/- 13.6 years) with a handicap of </=8 volunteered for the study. Following a standardized warm-up, subjects proceeded to hit 5 wiffle golf balls with a 5 iron while their CHS was measured. Rotational trunk flexibility was measured on a trunk rotator machine. An index of total body rotational power was measured through a hip toss with a 3-kg medicine ball while an 8-repetition maximum (RM) on a pec deck machine was used to measure chest strength. Pearson correlations were used to assess the magnitude of the relationships between CHS and the measures of flexibility, power, and strength. Partial correlations were then run to assess the effect of handicap on the observed relationships. The only variables that were significantly correlated to CHS were chest strength (r = 0.69, p < 0.05) and total body rotational power (r = 0.54, p < 0.05). These relationships were unchanged when the effect of handicap was controlled for. The results of this study show that strength of the chest in the pec deck motion and total body rotational power significantly correlate with CHS in male golfers. This information can be used by practitioners to develop training programs and field tests for golfers.
本研究的目的是调查男性高尔夫球手中柔韧性、力量和爆发力与杆头速度（CHS）之间的关系。15名差点指数≤8的高尔夫球手（平均年龄±标准差：34.3±13.6岁）自愿参与本研究。在进行标准化热身之后，受试者使用5号铁杆击打5个塑料高尔夫球，同时测量他们的杆头速度。在躯干旋转机上测量躯干旋转柔韧性。通过用一个3千克的药球进行臀部抛投来测量全身旋转爆发力指数，同时使用坐姿推胸器械上的8次重复最大值（RM）来测量胸部力量。使用皮尔逊相关性分析来评估杆头速度与柔韧性、力量和爆发力测量指标之间关系的强度。然后进行偏相关性分析以评估差点指数对观察到的关系的影响。与杆头速度显著相关的唯一变量是胸部力量（r = 0.69，p < 0.05）和全身旋转爆发力（r = 0.54，p < 0.05）。在控制差点指数的影响后，这些关系没有变化。本研究结果表明，在坐姿推胸动作中的胸部力量和全身旋转爆发力与男性高尔夫球手的杆头速度显著相关。从业者可利用这些信息为高尔夫球手制定训练计划和现场测试。
