Abstract

Eight female hooded rats were divided into two groups, one active (unrestricted) and another severely restricted in muscular activity. Colonic temperatures and vaginal smears were taken daily to determine body temperature throughout one natural estrous cycle. Body temperatures for the active and restricted groups were about the same for all phases of the estrous cycle except early estrus. During this phase the restricted group, as predicted, demonstrated a much greater dip in temperature than did the active group. It was hypothesized that the increase in running activity one normally records during estrus is a temperature control mechanism rather than an indicant of increased drive.
