  1. * statistically different from the previous result (post 5 is different from post 0,…, post 8 from post 5). P < 0.05.
  2. The blood parameters were collected 1 min before the test at the end of the warm-up (pre-test), and at 0, 5 and 8 min of passive recovery following the Tlimsupra test.
  3. The blood variables are oxygen saturation (SaO2), lactate concentration [La] and bicarbonate concentration [HCO3 -], pH and partial pressure for O2 (PaO2) and CO2 (PaCO2). n = 11.
