The impact of HRup orHRdown at successively higher levels of analysis, from the H-reflex elicited in the conditioning protocol to key features of locomotion (i.e., step-length and step-cycle symmetry)

Level of Analysis	HRup	HRdown
Protocol H-reflex	↑	↓
Locomotor H-reflex	↑	↓
Locomotor burst	↑	No change
Ankle angle	↑	No change
Step length and symmetry	↑	No change
