摘要

剑道是决策运动的一个例子，涉及到竹剑(竹剑)快速交替的防御和进攻动作。这项研究的目的是反应时间和肌肉激活模式在两种类型的剑道打击。材料与方法:剑道运动员(n=7)、其他运动员(n=7)和久坐不动的参与者(n=7)分别进行10次“Men”打击(目标高度1.65 m)和10次“Kote”打击(目标高度1.15 m)。使用肌电(EMG)记录双侧肱二头肌、双侧肱三头肌和右侧尺侧腕屈肌的肌肉活动。结果:剑道运动员和其他运动员的反应时间与久坐不动的参与者相似，但反应时间更短。剑道运动员在两项任务中表现出不同的肌肉激活时间，而其他运动员和久坐的参与者在时间上没有差异。剑道运动员和非剑道参与者(其他运动员和久坐不动的参与者)的肌电信号大小不同。结论:在决策运动中，神经肌肉控制的差异与运动经验有关，而与反应时间无关。

Response time and muscle activation patterns of the upper limbs during different strikes in kendo

Background Kendo is an example of a decision-making sport and involves rapidly alternating defensive and offensive movements of a shinai (bamboo sword). The aim of this study was response time and muscle activation patterns during two types of kendo strikes. Material & Methods:: Kendo athletes (n=7), other athletes (n=7), and sedentary participants (n=7) performed 10 “Men” strikes (target height, 1.65 m) and 10 “Kote” strikes (target height, 1.15 m). Muscle activity of the bilateral biceps brachii, bilateral triceps brachii, and right flexor carpi ulnaris muscles was recorded using electromyography (EMG). Results: The kendo and other athletes had similar response times and shorter response times than the sedentary participants. The kendo athletes exhibited different timing of muscle activation onset between the two tasks, whereas the other athletes and sedentary participants exhibited no differences in timing. The EMG magnitude differed between kendo athletes and non-kendo subjects (other athletes and sedentary participants). Conclusions: In decision-making sports, differences in neuromuscular control, but not in response times, are associated with athletic experience.
