Accumulation of 2H2O in plasma and eccrine sweat during exercise-heat stress.

摘要: The purpose of this research was to characterize the movement ingested water through body fluids, during exercise-heat stress. Deuterium oxide (2H2O) accumulation in plasma and eccrine sweat measured at two sites (back forehead). exercise 14 males controlled via cycle ergometry a warm environment (60 min; 28.7°C, 51%rh). Subjects consumed 2H2O (0.15 mg kg−1, 99.9% purity) mixed flavored, non-caloric, colored before exercise, then 3.0 ml kg−1 containing no every 15 min exercise. We hypothesized that transit from mouth skin would occur min. appeared rapidly both (P 0.05) mass, volume deuterium dose, or total fluid consumed. These findings clarify time course glands, demonstrate considerable differences enrichment versus sweat.
