Fig. 4

Average and standard deviation of the average rate of change (P1-N1, N1-P2, P2-N2) of frontal-plane whole-body angular momentum (H) in different transition phases. Comparisons were performed among anticipation states (filled shapes), cutting styles (unfilled circles and diamonds) and complexity tasks (unfilled squares and triangles). Green filled squares indicate anticipated states, and red filled triangles indicate unanticipated states. Green unfilled squares indicate cuts, and red unfilled triangles indicate cut/stairs transitions. Green unfilled circles indicate crossover styles, and red diamond indicate sidestep styles. Each marker above represents a walking condition of a main factors or an interaction scenario of two main factors, and consists of different levels of interactions or main factor, respectively. Comparisons were also performed between each transition scenario and straight walk. Black dots indicate straight walk in both anticipation states. Brackets indicate significant differences between two transition scenarios. Significant differences between each transition scenario and straight walking are indicated by ‘*’. ‘+’ indicates significant differences between crossover and sidestep cut styles within the same anticipation states, and ‘×’ indicates significant differences between cut and cut/stairs within the same anticipation states or the same cut styles
