Figure 1. Experimental set-up for leg cycling on the ergometer.

Figure 1

Nerve stimulation was delivered during cycling and static trials at the 12'clock position of the right pedal crank (thick lines of red). Green lightning bolt: median nerve stimulation (test stimulation for evoking the H-reflex). Blue lightning bolt: superficial radial nerve stimulation (conditioning stimulation to reduce Ia PSI and facilitate flexor carpi radialis (FCR) H-reflex amplitudes) Red lightning bolt: radial nerve stimulation (conditioning stimulation to increase Ia PSI and suppress FCR H-reflex amplitudes).
