  1. The relative performance change (EXSCAT – RSCAT) is indicated for each sub-mode and testing condition (EXSCAT or RSCAT performed first). *denotes significant difference EXSCAT vs RSCAT. The LOA is indicated for sub-mode and testing order. The Wilcoxon rank sum test p-value signifies differences between RSCAT and EXSCAT for that testing order. The odds ratio shows the odds (95% CI) of exercise performance improving relative to rest when tested in the REST1-EX2 order
  2. aAdjusted for gap between days in subsequent SCAT, categorised as within the same day (0), and on a different day (1)
