Columns are, from left to right: the mean maximal M wave amplitude(Mmax)with standard deviation(S.D.) measured during locomotion, the mean M wave amplitude(M) with S.D. used as the conditioning stimulus during locomotion, the peak H reflex measured during locomotion expressed as the percentage of Mmax also measured during locomotion, and the peak H reflex measured during locomotion but expressed as the percentage of Mmax during standing(peak H reflex(C&S)). A, walking at 4.5 km h−1. B, running at 8.0 km h−1. C, running at 12.0 km h−1. D, running at 15.0 km h−1.
