Function of gastrocnemius during running (Black plots = significant effects with group difference (actual units and as a percentage) adjacent the right error bar, Grey plots = non-significant effects). Abbreviations: LG, lateral gastrocnemius; MG, medial gastrocnemius; A-pre, amplitude at 100ms pre-heel strike; A-post, amplitude at 100ms post-heel strike, A-pre-p, amplitude during pre-activation phase; A-wa-p, amplitude during weight acceptance phase; A-po-p, amplitude during push-off phase; T-ini, time of start of activation; T-max, time of maximum activation; T-total, total time of activation; B, barefoot; S, shod; Norm. units, normalised to mean amplitude during the entire gait cycle. * Variables were reported to have statistically significant differences between groups in original study.
