Research Abstract

This study aimed to investigate the central control mechanism behind the rapid adjustment of muscle output during isometric elbow flexion by analyzing tension and muscle activity as an indicator. In particular, attentions were focused on rapid decrease or increase in muscle output and muscle output was adjusted by unilateral or bilateral. In conclusion, characteristics of motor units mobilized during increase and decrease muscle output and extension in adjustment time when muscle output was decreased were revealed.
