Answer 20

30 min of moderate physical activity at least 5 days/wk

20 min of vigorous physical activity at least 3 days/wk

Question 21

Relationship Between Physical Activity and Health Conditions

Answer 21

Inverse
More PA - less risk
Less PA - more risk

Question 22

CVD Relationship with Physical Activity

Answer 22

Risk of sudden cardiac arrest or MI is low in healthy individuals doing moderate activity
Increase in risk of individuals with diagnosed CVD

Question 23

Common Causes of Death in Young Individuals

Answer 23

Not from CVD, but from congenital or hereditary abnormalities

Question 24

Cardiac Death in Adults

Answer 24

Higher due to higher prevalence of CVD
Occur with more vigorous intensity then compared to younger individuals
Physically active are at 30-40% lower risk of developing CVD then inactive

Question 25

Reducing Exercise-Related Cardiac Events

Answer 25

Know pathologic conditions associated with exercise-related events
Know nature of cardiac symptoms
Pre-participation screenings
Health care facilities are trained in managing cardiac emergencies
Modify exercise programs as needed
