What is a possible mechanism by which chronic exercise training may reduce resting blood pressure in a person with hypertension?

Chronic exercise training is known to have a significant positive impact on cardiovascular health, particularly in reducing resting blood pressure in individuals with hypertension. One of the mechanisms that contribute to this effect is a reduced heart rate. Regular physical activity strengthens the heart muscle, allowing it to pump more efficiently, which can lead to a lower resting heart rate.

When the heart becomes more efficient and pumps effectively with each beat, it requires fewer beats to circulate blood throughout the body at rest. This reduction in heart rate can lower cardiac workload and decrease overall blood pressure. Additionally, as the heart becomes more accustomed to physical activity, it adapts in such a way that it maintains lower levels of sympathetic nervous system activity, further contributing to lower resting blood pressure.

This reduction in heart rate is particularly important for individuals with hypertension, as it can directly influence their blood pressure levels and contribute to better overall cardiovascular health.
