Research Abstract

The effects of fluid intake on thermoregulatory and cardiovascular responses during prolonged exercise in the heat were examined by measuring the effects on body temperature of: 1) fluid temperature of 5, 15, 25 or 35 degrees C with constant intake volume, 2) intake volume during sports activity in summer, and 3) fluid temperature and volume with intake ad libitum. The results suggest that intake fluid temperature significantly affected body temperature during prolonged exercise in a hot environment, even within the fluid temperature range of 5-15 degrees C, and that intake of fluid at a temperature of 5 degrees C can be recommended as a strategy for physically cooling the body in order to prevent heat disorders during exercise in the heat.
