Study Notes
Physical Activity and Coronary Heart Disease (CHD)
- Active individuals exhibit CHD rates approximately 50% lower than those who are least active.
- Engaging in regular physical activity is crucial for cardiovascular health.
Recommendations for Physical Activity
- The American Heart Association advises adults to engage in at least 30 minutes of moderate-intensity physical activity most days of the week.
- For weight loss or maintenance, a target of 60 minutes of physical activity is recommended daily.
- Physical activity can be performed in shorter sessions throughout the day if preferred.
Caution for Individuals with Heart Disease
- Vigorous physical activity poses an increased risk of heart attack and sudden death for those with diagnosed heart conditions.
- Sedentary adults should gradually increase their physical activity levels to avoid health risks.
