  1. Statistical analysis includes post hoc comparisons of two factors separately using repeated measures OUT vs AM and AM vs SDM conditions. When repeated measures overall testing showed that the main effects were not significant (p > 0.05), post-hoc tests were not conducted and not presented. Bold values indicate significant differences (p < 0.05). D-FLEX: dorsiflexion; P-FLEX: plantar flexion; FLEX: flexion; EXT: extension; BF: braking force; PF: propulsive force; ES: early stance; MS: mid-stance; LS: late stance
