Blood pressure reduction following prolonged exercise in young and middle-aged endurance athletes.

Background: Previous studies examining the relationship between exercise dose and post-exercise hypotension (PEH) have employed a limited range of exercise duration and subject age. We extended the dose-response curve by studying two intensities of prolonged exercise that may produce a greater magnitude of PEH and reveal age differences in the exercise dose-response relationship for PEH.

Methods: Two groups of healthy recreational endurance athletes were studied: Young (n = 17; age 28 ± 1.
