Study procedure. An initial warm-up was performed for 10 min at 2 W·kg⁻¹. A further passive rest for 5 min followed. A 15-s all-out sprint cycling test was performed in the isokinetic mode set to a cadence of 120 rpm. Participants performed the test in the sitting position on the ergometer. Oxygen uptake at 5-min rest, and during as well as up to 6 min after 15-s all-out sprint cycling test was measured. Capillary blood was collected from the earlobe (20 μL) before and in minutes' interval (1st to 10th) after the 15-s all-out sprint cycling test. $\dot{\mathrm{V}}$ O₂, oxygen uptake.
