Treatment ID:	TR001997
Treatment Summary:	Training intervention. All training sessions were performed on an electronically braked cycle ergometer (Velotron, RacerMate, USA), following an 8-min warm up (see 20k-TT) and consisted of HIIT (2:1 work-to-rest ratio). Training intensity was set relative to ẆLT (rather than ẆPeak) so as to induce similar metabolic and cardiac stresses amongst participants of differing fitness levels75. Exercise intensity was maintained between ẆLT and ẆPeak throughout the entire study so that training volume was the only manipulated variable between the 3 phases. NVT phase. This consisted of 6 HIIT sessions within 2 weeks of 5 to 7 4-min cycling intervals interspersed with a 2-min recovery at 60 W. Exercise intensities were defined as [ẆLT + x(ẆPeak-ẆLT)], with x increasing from 0.5 to 0.7 throughout the phase. HVT phase. Participants performed HIIT twice a day for 20 consecutive days; training sessions consisted of either 7 to 10 4-min intervals interspersed with a 2-min recovery at 60 W at intensities ranging from [ẆLT + 0.5(ẆPeak-ẆLT)] to [ẆLT + 0.8(ẆPeak-ẆLT)], or 15 to 20 2-min intervals at intensities ranging from [ẆLT + 0.5(ẆPeak-ẆLT)] to [ẆLT + 0.95(ẆPeak-ẆLT)], interspersed with a 1-min recovery at 60 W. Single session duration increased from ~45 min to 60 min. RVT phase. The RVT phase consisted of 6 HIIT sessions in 6 days; participants performed 10, 9, 8, 7, 6, and 4, 4-min intervals interspersed with a 2-min recovery at 60 W, at an intensity of [ẆLT + x(ẆPeak- ẆLT)], with x increasing from 0.5 to 0.7 throughout the phase.
