It is a critical tactic in combat sports to launch consecutive attacks that consist of two or more individual kicks strung together in time. The study aimed to assess how the number of round kicks would impact reaction time (RT) and movement time (MT). Twenty-eight experienced taekwondo athletes performed one of four different kick responses randomly in a simple RT paradigm: 1) clenched lead fist without a kick (task A); 2) round kick following task A (task B); 3) double kick following task B (task C); and 4) turning kick following task C (task D). Electromyography recordings from the thenar muscle and acceleration impulses from a triaxial accelerometer positioned at the heavy bag were used to determine premotor time and kick time, respectively. Repeated-measures ANOVA revealed that task B, task C, and task D significantly increased RTs (p < 0.001). The RT of task D was longer than that of task B and task C (p < 0.001). The movement time of the round kick in task C and task D was longer than in task B (p < 0.001). The movement time of the double kick in task D was longer than in task C (p = 0.003). Additional time is required to prepare for multi-kicks responses. An increased number of individual kicks to execute as a whole may slow down the kick movement.
在格斗运动中，连续发动由两个或更多单个踢腿连贯而成的攻击是一项关键战术。本研究旨在评估回旋踢的次数如何影响反应时间（RT）和动作时间（MT）。28名经验丰富的跆拳道运动员在简单反应时范式中随机执行四种不同的踢腿反应之一：1）握紧前手拳但不踢腿（任务A）；2）在任务A之后进行回旋踢（任务B）；3）在任务B之后进行双踢（任务C）；4）在任务C之后进行转身踢（任务D）。分别使用来自大鱼际肌的肌电图记录和位于沙袋处的三轴加速度计的加速度脉冲来确定运动前时间和踢腿时间。重复测量方差分析显示，任务B、任务C和任务D显著增加了反应时间（p < 0.001）。任务D的反应时间比任务B和任务C的长（p < 0.001）。任务C和任务D中回旋踢的动作时间比任务B中的长（p < 0.001）。任务D中双踢的动作时间比任务C中的长（p = 0.003）。进行多踢腿反应需要额外的准备时间。作为一个整体执行的单个踢腿数量增加可能会减慢踢腿动作。
