Two possible explanations for why diastolic blood pressure might actually DROP slightly after a period of intense exercise.
What are...

a) artery walls are relaxed/dilated in response to an increased demand for bloodflow (= lower BP)

b) profuse sweating results in dehydration, which causes a slight drop in blood volume (= lower BP)
