Experimental design. Gray rectangles represent voluntary quadriceps contractions at maximal (MVC) or submaximal intensity at 50 and 30% of MVC. Superimposed and control doublets, maximal M-waves (Mmax), and maximal H-waves (Hmax) were delivered via electrical stimulation over the femoral nerve. Motor-evoked potentials (MEP) were delivered over the motor cortex via transcranial magnetic stimulation.
