Respective groups consisted of: short interval training (1MIN-HIIT): 10 repetitions of 1 min bouts with 1 min rest periods at 90% of the PO obtained during VO2peak (total of 10 min of cycling) [19]; high-intensity training (2MIN-HIIT): 5 bouts of 2 min cycling with 1 min recovery utilizing undulating intensities (80%–100% VO2peak; Figure 1) (modified from: [16,20]), or no exercise at all.
