| Research Abstract |
The aim of the present study was to clarify standing posture control、 with and withoutmuscle tension in biarticular muscles、 in response to external disturbance (the ground suddenly shifting). Subjects、 seven healthy students、 were asked to maintain a standing posture on a force plate during anterior and posterior external disturbance (movement of the plate) with and without muscle tension in biarticular muscles. Ground reaction force was captured、 to analyze muscle activity in the lower limbs and joint angles. With both posterior and anterior external disturbance、 there was an increase in control in the direction towards the floor due to muscle tension、 and there were small changes observed in muscle activity and joint angles. The results suggested that monoarticular and biarticular muscles were made to function cooperatively、 reducing activity、 andbiarticular muscles have an important adjusting function in postural control.
