| Research Abstract |
The present study aimed to investigate the strategies for sustaining joint toque exertion during fatiguing isometric contractions from a view point of synergistic muscle activities. In Low task, the synergist muscles contracted alternately through the task to sustain the given torque level. In Middle task, on the other hand, all three synergist muscles kept contracting from the beginning of task, with the activation level of one or two muscles increasing with time. These results indicate that the strategy for keeping joint torque during fatiguing-task differs between the joint torque exertion levels.
