    • A plurality of golf clubs having mutually different flex point rates of a shaft is prepared. A subject hits a golf ball with one reference club included in the golf clubs. A face angle of the golf club immediately before hitting is measured by an apparatus 10. A recommended flex point rate P is calculated by substituting, into the following mathematical expression, the face angle Q and the flex point rate R of the reference club: P=0.8648·Q+R−5.033 A golf club having a shaft whose difference between the flex point rate and the recommended flex point rate P is within a predetermined range is selected as a recommended club. The subject hits a golf ball with the recommended club. The apparatus 10 measures a speed, a launch angle, a backspin speed, a sidespin speed, and a deflection angle of the golf ball.
    • 制备了具有相互不同的轴的弯曲速率的多个高尔夫球杆。 一个主题打高尔夫球,一个参考俱乐部包括在高尔夫俱乐部。 通过装置10测量刚刚在打击之前的高尔夫球杆的面角。推荐的弯曲点速率P通过以下数学表达式代入参考球杆的面角Q和弯曲点速度R来计算:P = 0.8648·Q + R-5.033选择具有弯曲点速率和推荐弯曲点速度P之间的差在预定范围内的轴的高尔夫球杆作为推荐球杆。 该主题与推荐的俱乐部打高尔夫球。 装置10测量高尔夫球的速度,发射角度,后旋速度,侧翼速度和偏转角度。
