Abstract

We have studied the physiological and behavioral responses in male rats to copulation and exercise. For this purpose, electrocardiographys (ECGs) were recorded from conscious and unrestrained rats using radiotelemetry system, Heart rate during copulation rose sharpiy following the induction of a receptive female, showed a peak of about 520 bpm during each ejaculation series, and then rapidly decreased. To compare the rate of decrease after ejaculation with that following
vigorous exercise, we run male rats on a motor wheel until heart rate became to the same value during ejaculation. Foliewing the cessation of exercise, heart rate decreased gradually. The possible role of the autonomic nervous system in the changes of heart rate during copulation and exercise is discussed.
