Figure 1. Full feedback procedure.

A: Players performed three valid handball-specific sidestep cuts on each leg that served as their baseline (PRE) values. The order of legs was randomized. B: Assessment of technique variables and their magnitudes of the first leg. C: Visual feedback with bar graphs and stick figures and standardized verbal feedback for the first leg. Feedback was provided on the peak external knee abduction moment (pKAM) and the first technique variable in the hierarchical order of foot strike angle (FSA), knee valgus angle (VAL), and vertical impact velocity (VIV) that exceeded its predefined cut-off value. D: Players performed three valid post-feedback (POST) cuts. Verbal instructions using a combination of internally- and externally-directed foci of attention were provided before each POST cut to guide technique modifications. E: Assessment of pKAM and presentation of results (bar graphs, stick figures) to players. When feedback ceased, focus shifted to the other leg, starting with step C.
