(a) Mean ± SE SICI obtained during 70%, 80% and 90% into the relaxation period during the grip-and-relax trials (Experiment 1) and sustained contraction trials at the matching background EMG levels (Experiment 2) in Study 1. SICI was 41% greater during relaxation than sustained contraction (p < 0.05). (b) Mean ± SE nonconditioned and conditioned MEPs obtained during 70%, 80% and 90% into the muscle relaxation period (Experiment 1) and during sustained contraction at the matching background EMG levels (Experiment 2) in Study 1.
