Abstract
The heart rate (HR) of male hooded rats was recorded in a nonhome cage for three weeks. Then they were deprived of water (Group 1, N = 6) or food (Group 2, N = 6) up to 96 h. HR was recorded at 8 h, 24 h, 48 h, 72 h, and 96 h of deprivation. The HR of Group 1 increased linearly with the duration of water deprivation, while that of Group 2 showed an inverse U-shaped function. These functions suggest that HR is influenced by two concomitant conditions: dehydration and metabolism.
