  1. All data are reported as means ± standard deviation, unless specified otherwise. Effect sizes reported for between exercise [7] and performance standard [31]. A positive effect size indicates that the left-hand column (farmer’s walk or higher performer) had a greater value than the respective right-hand column (unloaded walk or lower performer). *Significant difference to unloaded walking; †significant difference to low performing athletes, ☼significant difference to acceleration phase, ˟comparison between phase based on distance, AP acceleration phase, ave average, GRF ground reaction force, MVP maximum velocity phase, SVP sub-maximal velocity phase
