During voluntary movement, the smaller motor units are activated first followed by the contractions of the larger motor units. That being said, only during maximal effort are the larger motor units active. Due to biophysical properties of muscle, the order of the motor unit activation is reversed with the application of muscle stimulation. When using NMES, the machine will stimulate the nerves at the motor point. The muscle will then expand and contract similarly to a voluntary contraction. This study explores the potential of combining voluntary movement and muscle stimulation. To produce muscular contraction, sufficiently high intensities are commonly used and can be applied to the muscle during movement or without movement occurring.
Peer review refers to the work done during the screening of submitted manuscripts and funding applications. This process encourages authors to meet the accepted standards of their discipline and reduces the dissemination of irrelevant findings, unwarranted claims, unacceptable interpretations, and personal views. Publications that have not undergone peer review are likely to be regarded with suspicion by academic scholars and professionals.
