跆拳道的进攻与防守是教练员、运动员常提到的话题之一。然而,在有利状态下如何抓住时机发动进攻以及在不利条件下如何采取合理防守,则是需要从理论上加以讨论的问题。从生物力学角度对跆拳道进攻与防守的基本要素等问题进行了分析与探讨,旨在揭示其内在的规律与特点,为跆拳道的教学与训练提供相应的理论依据。 Taekwondo offensive and defensive coaches, athletes often mentioned one of the topics. However, how to seize the opportunity to launch an offensive under the favorable conditions and how to adopt a reasonable defense under unfavorable conditions is a problem that needs to be theoretically discussed. From the biomechanical point of view, the basic elements of taekwondo offense and defense are analyzed and discussed in order to reveal its inherent laws and characteristics and to provide corresponding theoretical basis for the teaching and training of taekwondo.
