Mean changes in iEMG (%) in the short- (SLR), medium- (MLR), and long-latency responses (LLR) after perturbations during marching in place (protocol 1). iEMG data are normalized to baseline values. Significant changes in response to the training intervention (TTEST, Pt) with effect sizes (Cohen’s d, d) as well as time interactions (rmANOVA, P) with effect sizes (Partial Eta Squared, ηp2 ) are illustrated in bold in the right columns with Pt and P < 0.05.
