使用加速度计的测量反映了施加在躯干上的冲击。躯干加速度的测量有可能反映出采伐过程中躯干运动的典型特征。然而，分析躯干加速度数据在切割机动尚未进行。本研究旨在分析躯干加速度在切割机动检查任何性别差异或与姿势的关系。所有参与者（八名男性和八名女性大学足球运动员）都执行了穿梭跑切割任务，并计算了躯干加速度（内侧、垂直和前后）。测量足部接触后200 ms内的峰值加速度（G）和总幅度，并根据矢状面摄像机拍摄的视频图像计算躯干前倾和股骨角。女性运动员的峰值垂直加速度（平均值，s）显著大于男性运动员（分别为-2.18，s = 0.84 G;-1.15，s = 0.45 G;p< 0.01）。内外侧和前后峰值加速度以及所有方向的总幅度在性别之间没有显著差异。垂直峰值加速度与躯干前倾和股骨倾斜呈中度负相关（r=-0.57，p < 0.05;r=-0.69，p < 0.01）。垂直加速度的性别差异有可能反映了女运动员的僵硬切割动作。上躯干的加速度可以作为评价切削运动的指标。
Measurements using an accelerometer reflect the impact applied to the trunk. Measurement of trunk acceleration has the possibility of reflecting the typical characteristics of trunk motion during cutting. However, analysis of trunk acceleration data during cutting manoeuvres has not been previously conducted. This study aimed to analyse trunk acceleration during cutting manoeuvres to examine any gender differences or a relationship with posture. All participants (eight male and eight female college soccer athletes) performed a shuttle run cutting task, and trunk accelerations (medio-lateral, vertical, and antero-posterior) were calculated. The peak acceleration (G) and total magnitude during the 200 ms after foot contact were measured, and the forward trunk inclination and femoral angle were calculated from the video images taken using a sagittal plane camera. Peak vertical acceleration (mean,s) was significantly greater among female athletes than among male athletes (−2.18,s= 0.84 G; −1.15,s= 0.45 G, respectively;p< 0.01). Medio-lateral and antero-posterior peak acceleration and the total magnitude in all directions were not significantly different between genders. Moderate negative correlations were found between vertical peak acceleration and trunk forward inclination and femoral inclination (r= −0.57,p< 0.05;r= −0.69,p< 0.01, respectively). The difference in vertical acceleration between genders has the possibility to reflect a stiff cutting movement among female athletes. The acceleration of the upper trunk may be an index for evaluating cutting movements.
