Abstract:
:Plasma 2H accumulation was measured in six male volunteers after ingestion of drinks containing trace amounts of 2H2O. Subjects fasted overnight and remained seated at rest or exercised on a cycle ergometer at 42, 61 or 80% of their maximum oxygen uptake (VO2, max). The rate of plasma 2H accumulation was faster at rest than during exercise at 61 or 80% of VO2, max (P less than 0.05), and was faster at 42 and 61% than at 80% of VO2, max (P less than 0.05). The time to peak plasma 2H concentration was longer during exercise than at rest. This suggests that strenuous exercise may reduce the availability of fluid ingested during exercise.
