Which of the following best describes the effect of physical inactivity on coronary heart disease?

The correct answer highlights a well-established relationship between physical inactivity and coronary heart disease. Lack of physical activity is a contributing factor that increases the likelihood of developing various risk factors associated with heart disease, including obesity, high blood pressure, high cholesterol levels, and diabetes. These conditions can potentially lead to the narrowing and hardening of arteries (atherosclerosis), ultimately heightening the risk of coronary heart disease.

Engaging in regular physical activity is beneficial as it helps maintain a healthy weight, lower blood pressure, improve cholesterol levels, and enhance overall cardiovascular fitness. In contrast, inactivity can lead to a sedentary lifestyle, which is directly linked to the worsening of these risk factors and an overall decline in heart health.

Understanding this relationship emphasizes the importance of incorporating physical activity into daily routines to mitigate the risk of developing coronary heart disease and promote cardiovascular wellness.
