[PURPOSE] The purpose of this study was to investigate the effects of different water temperature on heart rate, body temperature, cardiovascular stress and blood lactate concentration in male college students while performing aquatic exercise and at rest. [METHODS] A total of 8 participants performed aquatic exercise with intermittent rest periods. The water temperatures were 18°C and 38°C. Physiological variables were measured at rest and at 5, 10, 15 and 20 minutes post exercise. [RESULTS] The results showed that heart rate increased during rest and exercise periods at 38°C and the difference in increased heart rate was substantially larger as the temperature increased. Systolic blood pressure increased during rest and exercise periods when the temperature was low. During rest, the rate of increase on systolic blood pressure was higher at 18°C. Therefore, during exercise and rest periods, both high and low temperatures had no significant impact in accordance with the rate pressure product. During rest and exercise periods, 18°C caused body temperature to constantly stay low. During rest, 38°C caused body temperature to stay high. Blood lactate concentration constantly increased while resting at low temperature. At high temperature, blood lactate concentration did not change. On the other hand, while exercising, blood lactate concentration constantly increased at both 18°C and 38°C. [CONCLUSIONS] During rest and exercise at low and high temperatures, heart rate and systolic blood pressure showed an inverse response to water temperature changes, while the rate pressure product remained constant. During rest, the recovery mechanism is more effective at the higher temperature of 38°C. However, during exercise, the recovery mechanism is more effective at a water temperature of 18°C.
