| Outline of Final Research Achievements |
The purpose of this study was to elucidate the muscle fiber recruitment pattern during local blood flow restriction and intended to clarify the motor unit firing behaviors during voluntary muscular force production.
By using a portable pressure training machine, the surface EMG signal in pressurization were recorded and compared during isometric force exerted the same level in a non-pressurized.
The main result of this study is that the amplitude of the surface EMG signal than non-pressurized in the pressurization has been shown to be significantly higher. The results of this study, when the same level of force exerted, pressurization suggests that many motor units than non-pressurized is recruited. In the future, verification is expected of using a more direct experimental system that can record and analyze the motor unit firing dynamics.
