Responses throughout the contraction protocol when both limbs were active: abduction forces for both limbs and superimposed twitch of the contralateral limb evoked with TMS (A) and FDI EMG amplitude for both limbs and level of VA for the contralateral limb assessed via cortical stimulation (B). Data are presented for the phases of the fatigue protocol when both limbs were maximally contracting. *P < 0.05, nonfatiguing limb is different from nonfatiguing control. †P < 0.05, fatiguing limb is different from fatiguing limb control. Error bars represent SE.
