SD: standard deviation. bpm: beats per minute. Δ%: increment percentage regarding value of the previous stage. The Δ% was calculated with the standard formula: change (%) = [(value of the pedalling cadence stage – value of the previous pedalling cadence stage) / value of the previous pedalling cadence stage] x 100. VO2max: maximum oxygen consumption. VO2: oxygen uptake taking in account bodyweight; VE: pulmonary ventilation. HR: heart rate. BL: blood lactate. RPE: overall body rating perceived exertion from Borg or Aquatic Cycling scales (ACS).

*: Significant difference (p < 0.05) regarding value of the previous stage.

#: Trend of difference (p= 0.12) regarding previous stage.
