This study aimed to elucidate the movements requiring greater trunk accelerations and its frequencies during badminton games, and compare the acceleration components among such movements. Trunk acceleration was measured using a triaxial accelerometer during badminton games. The moments that generated >4 G resultant acceleration were extracted, and movements consistent with the extracted moments were identified. We calculated the extracted movement ratio and frequency and compared the resultant, mediolateral, vertical and anteroposterior accelerations between the top five extracted movements. There were 1,342 movements that generated >4 G [mean, 7.72 (95% confidence interval, 7.31-8.14) cases/min]. The top five movements were lunging during underhand strokes with the dominant hand side leg, landing after overhand strokes on the dominant and non-dominant hand side leg, and cutting from a split step using the dominant and non-dominant hand side leg. Landing on the dominant hand side leg had a greater resultant acceleration than the other movements and had the greatest impact during the badminton game. Lunging during underhand strokes on the dominant hand side leg had greater mediolateral acceleration than the other movements. These results reflected the properties of badminton.
本研究旨在阐明羽毛球运动中需要较大躯干加速度的动作及其频率，并比较这些动作中的加速度分量。在羽毛球比赛中使用三轴加速度计测量躯干加速度。提取产生>4G 合成加速度的时刻，并识别与提取时刻一致的运动。我们计算了提取运动的比例和频率，并比较了前五个提取运动的合成、横向、垂直和前后向加速度。有 1342 个动作产生了>4G[平均值，7.72（95%置信区间，7.31-8.14）例/分钟]。前五个动作是在惯用手侧腿下手击球时的前弓步，在惯用手和非惯用手侧腿上手击球后的落地，以及在使用惯用手和非惯用手侧腿的情况下从分腿步切入。在惯用手侧腿上的落地比其他动作产生更大的合成加速度，并且在羽毛球比赛中具有最大的冲击力。在惯用手侧腿下手击球时的前弓步具有比其他动作更大的横向加速度。这些结果反映了羽毛球的特性。
