本研究的目的是开发一种记录髂腰肌肌内肌电图（EMG）的方法，并将这种活动与足球场上踢球时的动力学联系起来。7名技术娴熟的足球运动员进行了3次最大速度定位球。用高速摄像机（400 Hz）拍摄踢腿，并从踢腿的5块肌肉获得肌电图记录，包括插入髂腰肌的金属丝电极。将EMG信号与从数字化胶片中计算的踢腿动力学进行比较。结果显示撞击前髋关节几乎没有扭矩反转。大腿段的角减速不会增加小腿的角速度（功- 3.57至0.0%）。髂腰肌在整个踢腿运动中都是活跃的（平均肌电图65.1-100.9%），即使在大腿减速的时候也是如此。导线电极可以成功地应用于快速卸载运动的肌电图记录。
The purpose of the study was to develop a method to record intramuscular electromyogram (EMG) from the iliopsoas muscle and to relate this activity to the kinetics during the soccer place kick. Seven skilled soccer players performed 3 maximal velocity place kicks. The kicks were filmed with a high‐speed camera (400 Hz) and EMG recordings were obtained from 5 muscles of the kicking leg, including wire electrodes inserted into the m. iliopsoas. The EMG signals were compared to the kinetics of the kicking leg, which were calculated from the digitised film. The results showed hardly any torque reversal about the hip joint before impact. Angular deceleration of the thigh segment did not increase the angular velocity of the shank (work ‐3.57 to 0.0%). M. iliopsoas was active during the entire kicking motion (average EMG 65.1–100.9%), even in the period when the thigh was decelerating. Wire electrodes can succesfully be applied to EMG recordings of fast unloaded movements.
