Effects of 10-week treadmill walking exercise training on motor-evoked potential (MEP) amplitudes. (A) Higher normalized MEP amplitudes (% of largest baseline MEP) demonstrate higher corticospinal excitability after the exercise training (ET) with return to baseline at 3-month follow-up (3-mo) in the hemisphere corresponding to the stronger hand at a transcranial magnetic stimulation (TMS) intensity of 145% of the active motor threshold (AMT) and (B) in the hemisphere corresponding to the weaker hand at the TMS intensities of 135 and 145% of the AMT.
