| 摘 要： | 目的:研究跆拳道后横踢4种战术动作的击打速度效果及对运动训练的启示。方法:以跆拳道后横踢"进攻""迎击""反击""近身"4种战术动作为研究对象,运用Motion-Analysis红外光点高速运动捕捉测试系统,研究在"空击"状态下部分关节转动幅度,人体重心位移变化,膝关节和踝关节的速度、加速度;并运用电子护具采集后横踢4种战术动作的击打力量。结果:进攻、反击战术动作在骨盆、髋关节旋转上与迎击、近身战术动作有差异(P<0.05),而在躯干、膝和踝关节旋转上没有差异(P>0.05)。进攻、迎击、近身战术动作的提膝向心加速和踝关节离心加速好于"反击"(P<0.05)。进攻、迎击、近身战术动作的提膝速度、击打速度均高于"反击"(P<0.05),击打力量也高于"反击",尤其是"进攻"(P<0.05)。"进攻"和"反击"重心移动速度高于"迎击"和"近身"(P<0.01),向心加速度也高于"迎击"和"近身",尤其是"进攻"(P<0.05),但"反击"移动方向与击打方向相反。结论:跆拳道后横踢4种战术中,"进攻"与"反击","迎击"与"近身"动作结构类似;"进攻""迎击""近身"在整个过程中各环节动作肌肉收缩用力、动量传递、击打力量方面均优于"反击",特别是"进攻"显著优于"反击"。在运动训练中,要以比赛规则为导向,了解战术运用现状,科学提高击打速度,提升击打效果策略,更新运动训练思路。

| Abstract: | Objective:To study the effect of hitting speed of four tactical movements of Taekwondo back roundhouse kick and its enlightenment for sports training.Methods:Took the four tactical movements of back roundhouse kick:"attack","block","counterattack"and"close quarter"as research subjects.The motion analysis infrared light point high-speed motion capture test system was used to collect the rotation amplitude of some joints,the displacement change of human body gravity center,and the speed and acceleration of knee and ankle joint under the condition of"shadow boxing".The electronic protector was used to collect the hitting strength of the four tactical movements.Results:The rotation of pelvis and hip joint in"attack"and"counterattack"was different from that in"block"and"close quarter"(P<0.05),while there was no difference in the rotation of trunk,knee and ankle joint(P<0.05).The knee lift centripetal acceleration and ankle centrifugal acceleration in"attack","block",and"close quarter"were better than that in"counterattack"(P<0.05).The knee lift speed and hitting speed of"attack","block",and"close quarter"was higher than that of"counterattack"(P<0.05),and the hitting strength was also higher than that of"counterattack",especially"attack"(P<0.05).The movement speed of gravity center in"attack"and"counterattack"was higher than that of"block"and"close quarter"(P<0.01),and the centripetal acceleration was also higher than that of"block"and"close quarter",especially"attack"(P<0.05),but"counterattack"and"attack"moved in opposite directions.Conclusion:"attack"is similar to"counterattack",and"block"is similar to"close quarter"in terms of tactical movement structure;"attack","block"and"close quarter"are superior to"counterattack"in muscle contraction strength,momentum transmission and hitting strength in the whole process,"attack"is especially superior to"counterattack".In training,we should take the rules of competition as the guide,and understand the current situation of tactical application to improve the hitting speed,improve the strategy of hitting effect,and update the concept of training in a scientific way. |
