During steady aerobic exercise like a five‑mile jog, his systolic pressure will be higher than at rest while diastolic is usually about the same or slightly lower. Net effect: widened pulse pressure and a modest rise in mean arterial pressure.
Why: cardiac output (HR and stroke volume) increases → raises systolic pressure; active muscle vasodilation lowers total peripheral resistance → diastolic stays the same or falls slightly.
