Table II:

Mean and standard error values, predicted by the regression models, for grouping A and grouping B of transition and non-transition runners. Grouping A: The transition runners shift from a typical or atypical rearfoot contact pattern (RF) towards a mid- or forefoot contact pattern (MF/FF). The non-transition runners remain with a typical of atypical rearfoot contact pattern. Grouping B: The transition runners shift from a midfoot contact pattern (MF) towards a forefoot contact pattern (FF). The non-transition runners remain with a midfoot contact pattern. χ² and p-values are given for the main effect of transition group on the selected variables. The mean values pre-transition for the non-transition runners are based on the values at the same speed as the speed pre-transition for the transition runners. A positive foot and ankle angle represent a dorsiflexed position.
