  1. The CV (range: minimum–maximum) was calculated for the voluntary force output (force), the corresponding root mean square EMG (rmsEMG·Mmax−1), the area of motor evoked potential (MEP·Mmax−1), cervicomedullary motor evoked potential (CMEP·Mmax−1) and the silent period (SP) at different contraction intensities (i.e. 100, 75 and 50% MVC)
