Supplementary Figure 7. Comparison within the medial gastrocnemius proximal, middle and distal region. Statistical Parametric Maps (SPM) show the comparisons between the foot strike and speed conditions for each muscle. SPM{F} trajectories reflect the magnitude of the test statistics. No thresholds are crossed by the SPM{F}, which indicating no statistically significant regional differences at any time point of the stride at group level. Abbreviations: FFS – forefoot strike running, RFS – rearfoot strike running.
