MICROANATOMY

Detailed explanation-1: -During exercise, increases in cardiac stroke volume and heart rate raise cardiac output, which coupled with a transient increase in systemic vascular resistance, elevate mean arterial blood pressure (60). However, long-term exercise can promote a net reduction in blood pressure at rest.

Detailed explanation-2: -Regular exercise makes the heart stronger. A stronger heart can pump more blood with less effort. As a result, the force on the arteries decreases. This lowers blood pressure.

Detailed explanation-3: -Exercise improves myocardial perfusion and increases high-density lipoprotein (HDL) cholesterol levels, all of which reduce stress on the heart and improve cardiovascular function in healthy and diseased individuals (11, 15, 29, 30).

Detailed explanation-4: -Combined with a healthy diet, aerobic exercise helps you lose weight and keep it off. You may feel tired when you first start regular aerobic exercise. But over the long term, you’ll enjoy increased stamina and reduced fatigue. You can also gain increased heart and lung fitness and bone and muscle strength over time.
