Table 1.

The mean (±SD) of the absolute data recorded from the non-exercised dominant elbow flexors muscles including compound muscle action potential (M-max) and motor evoked potentials (MEPs) and cervicomedullary evoked potentials (CMEP) normalized to M-max recorded from non-exercised biceps brachii muscle, MEP/CMEP ratio, duration of MEP silent period (SP) for two conditions (Intervention and Control) and five time points (repetition number 1, 3, 6, 9 and 12).
