Table 1 Coefficient of variation (CV) calculated for all variables across the 5 baseline measurements

From: The short-term recovery of corticomotor responses in elbow flexors

  100% MVC 75% MVC 50% MVC
Force (%) 13.3 (5–23) 14.7 (4–24) 12.2 (4–19)
rmsEMG·Mmax−1 (%) 17.8 (11–28) 21.8 (9–33) 19.4 (8–27)
MEP·Mmax−1 (%) 10.8 (5–19) 7.1 (2–16) 5.8 (3–9)
CMEP·Mmax−1 (%) 33.4 (16–56) 25.9 (9–46) 28.7 (13–49)
SP (%) 4.3 (2–7) 5.1 (2–10) 5.9 (3–11)
  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)
