Figure 3: Mean ± SE MEP amplitudes (expressed as a percentage of MMAX) obtained from the left untrained rectus femoris for the control (a), ST (b), and ST + V (c) groups before (light curve) and after (dark curve) training. Each recruitment curve is characterised by AMT, estimated slope and peak height (plateau), and the stimulus intensity at which the MEP amplitude is 50% of the maximum MEP . identifies AMT. *denotes significant increases in peak height post training . There were no differences in peak height between the ST and ST + V groups following training .
