How does regular exercise physiologically lower the risk of cardiovascular disease?
What will be an ideal response?
Answer: Exercise makes both the cardiovascular and respiratory system more efficient. The heart becomes stronger and able to pump more blood with each beat, increasing the number of capillaries delivering blood to working muscles. Exercise reduces triglycerides and boosts HDLs, and the weight loss it promotes helps reduce LDLs. These factors reduce the risk for cardiovascular disease. Moreover, exercise can prevent or reduce hypertension, a form of cardiovascular disease. Exercise also reduces the risk for metabolic syndrome and type 2 diabetes, two other risk factors for cardiovascular disease.
