在人体解剖学中,为了说明人体各部结构的位置关系和各环节的运动,人们假定设置了三个基本面(矢状面、冠状面、水平面)和三个基本轴(矢状轴、冠状轴、垂直轴). 运动轴的概念在体育运动实践中被广泛地应用着.比如,武术中的旋子;花样滑冰中的旋转;体操、跳水中的前、后翻腾,转体;以及体育技术动作中各关节的运动,都是人体或关节围绕单轴、双轴和三轴做转动动作的.人们之所 In the human anatomy, in order to explain the positional relationship of various parts of the human body and the movements of each link, it is assumed that three basic planes (sagittal plane, coronal plane, horizontal plane) and three basic axes (sagittal axis, coronal axis) are set. , the vertical axis). The concept of the movement axis is widely used in sports practice. For example, the rotation in the martial arts; the rotation in figure skating; the gymnastics, the front and back churning in the diving, the rotation; and the sports technique movements. The movements of the joints in the Chinese are the movements of the human body or joints around the uniaxial, biaxial, and triaxial axes.
