How does diastolic blood pressure respond to exercise?

Diastolic blood pressure typically remains stable or may decrease slightly during exercise, particularly during moderate-intensity activities. This response occurs because the heart is pumping more blood into the arteries to meet the increased demand for oxygen in active muscles, leading to a rise in systolic blood pressure. However, the vasodilation in the peripheral vessels allows for enhanced blood flow and reduces resistance in the arteries, which can result in a decrease or stabilization of diastolic pressure.

Understanding this physiological response is essential when monitoring an individual's cardiovascular response to exercise, as a stable or slightly decreased diastolic pressure indicates that the body is effectively managing blood flow while exercising. This knowledge helps exercise physiologists design safe and effective exercise programs for diverse populations, including those with cardiovascular concerns.
