一、前言人体四肢肌肉多为双关节肌和多关节肌。其中,双关节肌对四肢乃至人体整体的运动具有极重要的作用。从宏观上看,双关节肌依赖于独特的形态、结构及起止分布的特点而获得了某些特殊的功能优势,使其在参与生物运动链的多级控制,环节运动的多维约束、形成便利的骨杠杆运动形式、以及增强肢体运动效应等方面都发挥了单关节肌所不能替代的效果。诸
First, the foreword Most of human limb muscle Muscle and joint multi-joint muscle. Among them, the bilateral joint muscles on the limbs and even the whole body of the movement has a very important role. From the macroscopic point of view, the two types of articular muscles acquire some special functional advantages depending on the unique morphology, structure and the characteristics of starting and ending distribution, making them easy to participate in the multi-level control of the biological kinematic chain and the multi-dimensional constraints of the link motions Of the bone lever form of movement, as well as enhance the limb movement effects have played a single joint can not replace the effect. various
