| Popis: | Purpose: Mountain running races are becoming increasingly popular, although our understanding of the particular physiology associated with downhill running (DR) in trained athletes remains scarce. This study explored the cardiorespiratory responses to high-slope constant velocity uphill running (UR) and DR. Method: Eight endurance athletes performed a maximal incremental test and 2 15-min running bouts (UR, +15%, or DR, −15%) at the same running velocity (8.5 ± 0.4 km·h−1). Oxygen uptake (O2), heart rate (HR), and ventilation rates (E) were continuously recorded, and blood lactate (bLa) was measured before and after each trial. Results: Downhill running induced a more superficial E pattern featuring reduced tidal volume (p .05, ES = 0.68) despite lower E (p |
