| Popis: |
Venous blood samples were obtained from 18 marathon runners before and after the 27 km uphill portion of a 46 km transmountain race at altitudes of 1,950-3,400 m. There was an inverse correlation between blood lactate levels and running time (r = -0.83), with the runners with higher lactate levels completing the race in less time. The faster half of the group had higher blood levels of glucose and lactate and lower free fatty acid levels at 26 km distance and 3,400 m elevation. The elevated lactate concentrations in the blood of the faster runners suggest that anaerobic metabolism can contribute significantly to total energy production during prolonged exercise at high altitude. |
