ANOVA p values represent the main effects of foot strike pattern (FSP) and fatigue (TIME), and the interaction effect (FSP × TIME). Significant effects were highlighted in bold. Significant differences between Pre-MUM and Post-MUM in the NRFS subgroup were denoted by * (p < 0.05). Significant differences between the two subgroups at Pre-MUM or Post-MUM were denoted by $ (p < 0.05) or $ $ (p < 0.001).
