Abstract

During dynamic exercise in the heat, plasma noradrenaline (NA) levels are higher than during the same exercise in a thermoneutral environment (2). However, the exponential noradrenaline-heart rate relationship is unaltered in exercise with exogenous heat (2). Heat stress seems to have no added effect on plasma adrenaline (A) concentration (2). The aim of our study was to determine the effect of dry and humid heat on plasma NA and A concentrations during prolonged light exercise, and their relationships to core temperature and hemodynamic variables.
