| Outline of Final Research Achievements |
Three main experiments were performed to clarify the relationships between the muscle properties of lower leg and postural ability. (1) The tension would be equal inside lower leg, muscle stiffness will not be different with or without muscle activity. Muscle architecture will not effect on muscle stiffness. (2) To clarify muscle properties of lower leg and strategies for postural ability, subjects performed quiet standing and voluntary sway on the force platform. From the results of the change of muscle fiber and muscle activity, the timing of muscle activities were different even synergists. (3) The elderly people completed strength training for eleven weeks to improve muscle strength of their leg. After training period, muscle strength increased significantly, but postural ability was not change significantly.
