The aim of this research was to quantify the coordination pattern between thorax and pelvis during a golf swing. The coordination patterns were calculated using vector coding technique, which had been applied to quantify the coordination changes in coupling angle (γ) between two different segments. For this, fifteen professional and fifteen amateur golfers who had no significant history of musculoskeletal injuries. There was no significant difference in coordination patterns between the two groups for rotation motion during backswing (p = 0.333). On the other hand, during the downswing phase, there were significant differences between professional and amateur groups in all motions (flexion/extension: professional [γ] = 187.8°, amateur [γ] = 167.4°; side bending: professional [γ] = 288.4°, amateur [γ] = 245.7°; rotation: professional [γ] = 232.0°, amateur [γ] = 229.5°). These results are expected to be a discriminating measure to assess complex coordination of golfers' trunk movements and preliminary study for interesting comparison by golf skilled levels.
本研究的目的是量化高尔夫挥杆过程中胸部和骨盆之间的协调模式。协调模式采用向量编码技术计算，该技术已用于量化两个不同节段之间耦合角（γ）的协调变化。为此，招募了15名没有明显肌肉骨骼损伤史的职业高尔夫球手和15名业余高尔夫球手。在回摆过程中的旋转运动中，两组之间的协调模式没有显著差异（p = 0.333）。另一方面，在向下挥杆阶段，职业组和业余组在所有运动中均存在显著差异（屈伸：职业组[γ] = 187.8°，业余组[γ] = 167.4°；侧弯：职业组[γ] = 288.4°，业余组[γ] = 245.7°；旋转：职业组[γ] = 232.0°，业余组[γ] = 229.5°）。这些结果有望成为评估高尔夫球手躯干运动复杂协调性的一种判别方法，并为按高尔夫技能水平进行有趣比较的初步研究。
