| Outline of Final Research Achievements |
Interactions between lower limb muscles, which should be revealed for simulation of human motions, remains unclear. This study aims to reveal interactions between plantar flexor muscles and knee extensor muscles, from the perspective of the muscle synergy hypothesis. During isometric plantar flexor contraction at low intensities, the ratio in the activity between the medial gastrocnemius muscle and the soleus muscle changed with knee extensor contraction, and the activity of the medial gastrocnemius muscle relatively decreased. At high intensities of plantar flexion torque, the activity of the medial gastrocnemius muscle increased with knee extensor activity.
