Which statement about starting an exercise program for patients with congestive heart failure (CHF) is correct?

The statement regarding the warm-up and cool-down lasting five minutes is an important aspect of exercise safety and effectiveness for individuals with congestive heart failure (CHF). A structured warm-up is essential because it prepares the cardiovascular system for more intense activity by gradually increasing heart rate and circulation. This is particularly critical for patients with CHF, as their bodies require careful management of exertion levels to prevent undue strain on the heart.

Similarly, a cool-down period assists in gradually reducing heart rate and blood pressure after exercise, minimizing the risk of cardiovascular complications. For individuals with CHF, a cool-down can help prevent dizziness or other symptoms related to sudden changes in activity levels. By ensuring that both the warm-up and cool-down phases last adequately—typically longer than five minutes—the patient can transition safely in and out of the exercise session, which is crucial in their overall management and rehabilitation.

The other options relate to specific parameters around exercise intensity and stability which are significant, but the emphasis on the warm-up and cool-down duration allows for a more cautious and health-focused approach to initiating an exercise program for individuals with CHF.
