Characterization of motor unit activities during isometric elbow flexion with different speeds
Motor unit behavior is modulated by contraction force and speed, with faster contractions eliciting higher discharge rates and common drive. These findings underscore the neuromechanical adaptability of the motor unit system and have implications for motor function assessment, rehabilitation, and the development of myoelectric interfaces.
