这项研究调查了右手鼓手和非鼓手在用鼓槌快速重复单手敲击期间的表现和手腕肌肉活动。表演分析显示，鼓手和nondrummers之间的敲击频率和峰值敲击力没有差异，虽然鼓手表现出较少的变异性intertap间隔比nondrummers。通过记录右手腕的尺侧腕屈肌和桡侧腕伸肌的活动获得的肌电图（EMG）数据的分析揭示了两组之间的几个明显差异：鼓手表现出较低水平的肌肉cocontraction与手腕屈肌肌肉活动的早期下降和较小的变异性，在手腕屈肌的肌肉激活时间相比，nondrummers。我们认为，这些特征的手腕肌肉活动的鼓手已经获得了广泛的实践，有效地利用手腕肌肉和稳定的击鼓表演。
This study investigated performance and wrist muscle activity during rapid-repetitive unimanual tapping with a drumstick in right-handed drummers and nondrummers. Analyses of performances revealed no difference in tapping frequency and peak tap force between drummers and nondrummers, although the drummers showed less variability in intertap interval than the nondrummers. Analyses of the electromyographic (EMG) data obtained by recording the activity of the flexor carpi ulnalis and the extensor carpi radialis muscles of the right wrist revealed several distinct differences between the two groups: the drummers showed a lower level of muscle cocontraction together with an earlier decline of wrist flexor muscle activity and a smaller variability of muscle activation time in the wrist flexors compared with the nondrummers. We suggest that these characteristics in wrist muscle activity in the drummers have been acquired following extensive practice for the efficient use of wrist muscles and stable drumming performance.
