Question

• Describe the disease process of atherosclerosis.

• What role does LDL cholesterol have in this process?

• Why does atherosclerosis increase risk of a heart attack?

• What are the risk factors for heart disease (both behavioral and cardi

• What chamber of the heart is at the greatest risk of myocardial infarction?

• From the movie, explain why John has a heart attack

Answer

Atherosclerosis is a disease process in which plaque builds up in the arteries, narrowing them and reducing blood flow. LDL cholesterol plays a role in this process by contributing to the buildup of plaque. Atherosclerosis increases risk of a heart attack because the plaque buildup can cause a blockage in the arteries, leading to a lack of oxygen to the heart muscle, which can cause a heart attack. Risk factors for heart disease include smoking, high cholesterol, high blood pressure, diabetes, obesity, and lack of physical activity. The left ventricle of the heart is at the greatest risk of myocardial infarction due to its role in pumping oxygenated blood throughout the body. In the movie, John has a heart attack due to the buildup of plaque in his arteries, which caused a blockage and a lack of oxygen to his heart muscle.

What is the target range of METs for moderate and vigorous activity?

What three exercise types aro part of the 2018 guidelines? Define them.

What are the recommendations for children? Why is it important to emphasize guidelines for kids?

Answer

The weaknesses of the original Surgeon General's Report included a lack of specificity in the guidelines and a lack of emphasis on physical activity for children. The updated version of the SGR included more specific guidelines and emphasized physical activity for children. The original ACSM guidelines were designed to promote cardiorespiratory fitness. The current U.S. Physical Activity Guidelines (2018) for adults recommend at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic physical activity per week, and muscle-strengthening activities on two or more days a week. The target range of METs for moderate activity is 3.0-5.9 and for vigorous activity is 6.0 and above. The three exercise types recommended in the 2018 guidelines are aerobic activity, muscle-strengthening activity, and bone-strengthening activity. The recommendations for children are to engage in at least 60 minutes of physical activity per day, with a variety of aerobic, muscle-strengthening, and bone-strengthening activities. It is important to emphasize guidelines for kids to promote healthy habits and reduce the risk of chronic diseases.
