* Significantly different from NL (p < 0.05).
Bold: change larger than the average intra subject variability given in brackets.
Minimum added inertia is compared with no load; the table lists significant main effects (independent of speed) and significant interaction effects with speed, but only at speeds that were significant in pair wise comparisons.
