对快速单手敲击的研究已经假设人类自主节奏运动的速率极限是5-7赫兹，这相当于150-200毫秒的敲击间隔。事实上，在最近一次世界上最快的鼓手（WFD）比赛中，获胜者可以用手持鼓槌以10赫兹的速度演奏出这样的动作，这相当于100毫秒的ITI。因为比赛只测量了WFD的叩击次数，我们检查了M的稳定性和WFD潜在的手腕肌肉活动。通过比较WFD与两个对照组（非鼓手（NDs）和普通熟练鼓手（ODs））的表现和手腕肌肉活动，我们发现WFD在10 hz表演期间具有相对稳定的ITI和更明显的手腕肌肉活动。我们的结果表明，非常快速，稳定的敲击性能可以通过保持手腕关节柔顺而不是僵硬来实现。2009爱思唯尔爱尔兰有限公司版权所有。
Studies of rapid unimanual tapping have assumed that the human rate limit for voluntary rhythmic movement is 5-7 Hz, which corresponds to an inter-tap interval (ITI) of 150-200 ms. In fact, the winner of a recent contest to find the world's fastest drummer (WFD) can perform such movements using a handheld drumstick at 10 Hz, which corresponds to an ITI of 100 ms. Because the contest measured only the number of taps by the WFD, we examined the stability of the M and the underlying wrist muscle activity of the WFD. By comparing the performance and wrist muscle activity of the WFD with those of two control groups (non-drummers (NDs) and ordinary skilled drummers (ODs)), we found that the WFD had a relatively stable ITI and more pronounced reciprocal wrist muscle activity during the 10-Hz performance. Our result indicates that very fast, stable tapping performance can be achieved by keeping the wrist joint compliant rather than stiff. (C) 2009 Elsevier Ireland Ltd. All rights reserved.
