This study assessed the lead and trail arm peak and average extensor carpi ulnaris (ECU) muscle activity in association with tri-planar angular velocities of the lead and trail wrists during the golf swing. Fifteen sub-elite, male right-handed golfers ( = 34.7 years ±13.3, = 1.5 ± 2.2) were recruited to execute five shots each with their pitching wedge, 7-iron and driver clubs in an indoor golf simulator. Surface electromyography (EMG) sensors were placed over the ECU muscle belly and inertial measurement unit sensors were placed bi-laterally on the distal forearm and dorsum of the hand. There was a statistically greater recruitment of the trail ECU muscle during the downswing ( < 0.001) for all clubs. The lead ECU muscle was recruited more during the backswing ( < 0.001) and follow through ( < 0.024) phases. There were statistically different tri-planar movement patterns between the lead and trail wrist throughout all three phases of the golf swing. No significant relationships were found between downswing EMG data and clubhead kinematics at impact. In conclusion, differing wrist kinematics and associated muscle activity may contribute to the asymmetrical injury pattern seen clinically.
本研究评估了高尔夫挥杆过程中,领先手臂和跟随手臂的尺侧腕伸肌(ECU)的峰值和平均肌肉活动,以及领先手腕和跟随手腕的三平面角速度。招募了15名次精英、右利手男性高尔夫球手(年龄=34.7岁±13.3岁,差点=1.5±2.2),在室内高尔夫模拟器中,使用他们的劈起杆、7号铁杆和发球杆各击球5次。将表面肌电图(EMG)传感器放置在ECU肌腹上,将惯性测量单元传感器双侧放置在前臂远端和手背。对于所有球杆,在向下挥杆过程中,跟随侧ECU肌肉的募集在统计学上显著增加(P<0.001)。领先侧ECU肌肉在向后挥杆(P<0.001)和随挥(P<0.024)阶段的募集更多。在高尔夫挥杆的所有三个阶段中,领先手腕和跟随手腕之间存在统计学上不同的三平面运动模式。在击球瞬间,向下挥杆的EMG数据与杆头运动学之间未发现显著关系。总之,不同的手腕运动学和相关肌肉活动可能导致临床上出现的不对称损伤模式。
