目前已有許多高爾夫的研究利用慣性感測技術做為研究工具，進行動作分析並提出可信之數據，因此本研究欲使用慣性測量單元量測高爾夫球員進行不同推桿距離身體轉動情形。方法：實驗徵求10位高爾夫球員，將無線六軸慣性測量單元固定於受測者後背第五節胸椎（T5）位置，進行90公分與270公分之各10次推桿動作，量測身體軸轉動運動學參數。實驗結果利用MATLAB運算推桿身體轉動參數，本研究利用不同推桿距離探討上軀幹轉動情形。結果：不同推桿距離之上桿時間（p = .034）、下桿時間（p = .000）、下桿最大角速度（p = .000）、上桿總角度（p = .012）以及下桿總角度（p = .000）達到顯著性差異，而上桿最大角速度（p＞.05）則無達顯著性差異。結論：本研究利用慣性測量單元做為量測人體運動學參數是為一個可行性的方法。
Purpose: The aim of this study was to measure the body rotation when putting in different distances by the wireless inertial measuring unit. Methods: Ten golfers were required to conduct 2 tests, each for 10 times, with 90 cm and 270 cm putting test, with the wireless inertial measuring unit fixed on the subject's back by the fifth thoracic (T5) to measure the angle of body rotation. Using MATLAB software to calculated the body rotation kinematics parameters. In this study, we investigated the torso rotation kinematics parameter by putting in two different distances. Results: The 90 cm and 270 cm putting test on backswing time (p = .034), downswing time (p = .000), downswing maximum angular velocity (p = .000), backswing total angle (p = .012) and downswing total angle (p = .000) reached a significant difference, but the backswing maximum angular velocity was no significant difference. Conclusion: It is feasible that this study uses wireless inertial measuring unit to measure kinematics parameters.
