由于人体是由为数众多的活动关节所组成,其重量中心高于支点,而支承外形的面积却很小,所以保持人的自然直立姿势是一项极为重要的课题;解决这课题,需要牵动一系列的反射链。在苏联科学院信息传递问题研究所B.C.古尔芬克里(B.C.)和日本旭川医学院C.莫利(C.)联合写的著作中,介绍了他们对上述课题所作的实验:在人所站立的支承平台上作节奏性的不同频率的前后倾斜,把膝肌在此条件下产生的电活性、胫关节中的角度变化以及人体各点的运动状况都记录下来。可以确定,胫关节中的角度变化在相位上同平台的运动相吻合。在平台的运动同人体及头部的摆动之间有一个相位移动,该移动取决于扰乱作用的
Since the human body is composed of a large number of articulated joints whose center of weight is higher than the fulcrum and the area of the bearing shape is small, it is an extremely important issue to maintain the natural upright posture of a human being. To solve this problem, Series of reflective chains. In a book written jointly by BC Gulfin Kerry (BC), Institute of Information Transmission at the Soviet Academy of Sciences, and C. Morley, Japan’s Asahikawa Medical School, they present an experiment on the above subject: The support platform for rhythm of different frequencies of the front and rear tilt, the knee muscles in this condition, the electrical activity generated, changes in the angle of the tibia and the human body movements are recorded. It can be determined that the change in the angle in the tibia is in phase with the platform motion. There is a phase shift between the movement of the platform and the swing of the human body and head, which movement depends on the disturbing effect
