Pre-fatigue baseline values for the neurophysiologic outcome variables.

Data are mean values (±SD) of the three pre-fatigue baseline measures taken during short duration 3–5sec 15%MVC task-specific contractions. Asterisks (*) signify a task-specific difference between baseline values (p values ES: Effect size partial eta2; ICF: intracortical facilitation; LII: long interval inhibition; MEP: motor evoked potential; Mmax: maximum compound muscle action potential; MVC: maximum voluntary contraction; RMS EMG: root mean squared electromyographic amplitude; SICI: short interval intracortical inhibition; SP: silent period; spCMEP: cervicomedullary evoked potential elicited in the silent period.
