The aim of this paper is to investigate the effect on the physiological response of fluid ingestion before walking in a swimming pool. Nine healthy students were candidates for this study. First of all, they were divided into two groups water ingestion (W(+))(300Ml) before pool walking group and no water drinking (W(-)) beforehand. Body temperature was measured in the tympanic space and venodilation was measured in the fingers. Walking conditions were 3 km/h for 1,750 m in an indoor pool with a water temperature of 29.7±0.5°C, at a room temperature of 25.4±1.4°C and relative humidity of 79.4±4.3%. The pool was 25 m in length and 1.0 m deep. The following results were obtained: The values for tympanic temperature in the W(-) group were significantly higher than that of pre-walking (p<0.05). Vasodilation of the veins in the fingers significantly expanded in the group of W(+)(p<0.05). The values of systolic blood pressure(SBP) in the W(-) group decreased significantly in comparison partially (p<0.05).We could conclude that fluid ingestion before walking in a swimming pool has a good effect on tympanic temperature, venous dilation and systolic blood pressure.
