GRFs are reported in Newtons per kilogram, moments in Newton metres per kilogram, and powers in watts per kilogram

SD standard deviation, AP antero-posterior, GRF ground reaction force, SEM standard error of measurement

aSEM calculated in a previous study [18]

bDenotes non-normally distributed data tested with a Wilcoxon signed-rank test; confidence intervals were not calculated in this case
