Ventilatory Parameter during Recovery The average respiratory exchange ratio (RER) showed no differences between women and men at all measurement points at the end of the recovery periods for all three HIIT protocols with the different lengths of active recovery periods (1 min recovery: women 1.11 ± 0.08, men 1.12 ± 0.10; 3 min recovery: women 1.02 ± 0.06, men 1.03 ± 0.05; 10 min: women 0.92 ± 0.06, men 0.93 ± 0.06) There was a highly significant decrease in the RER with an increase in the recovery period from one to three and to ten min ( p < 0.001). 4.
