Average colonic temperature of groups of animals. Colonic temperatures were obtained before and after each 60 min of exercise sessions for last 4 consecutive days. Values are mean ± SD, n = 8 for sedentary control (C), n = 10 for exercise at 25 °C (WE), and n = 9 for exercise at 4 °C (CE) groups. *p < 0.001 compared to before exercise in the same group, †p < 0.001 WE versus both C and CE after exercise
