| Research Abstract |
This study investigated muscle architectural changes that are induced by pre-motion silent period (PMSP) before rapid voluntary movement to clarify muscle contractile behavior in skillful motions. This study found that knee extension velocity was increased with PMSP appearance. In addition, this study suggests that muscle architectural change during PMSP is the result of muscle relaxation behaviour rather than the result of muscle stretching behaviour.
