Cardiovascular disease guidelines - duration

• A. Upper body exercise increases dyspnea, must be monitored; allow sufficient rest between sets
• B. 30-60 minutes
• C. 10-20 minutes
• D. 60-90 minutes

Answer: (A)

In cardiovascular disease, safe exercise relies on watching how the body responds and adjusting the effort accordingly. Upper body work can provoke dyspnea (breathlessness) more quickly because it often causes a higher ventilatory and cardiac demand for a given workload. By monitoring dyspnea and allowing sufficient rest between sets, you keep the activity within a safe range for each person and can progression gradually as tolerance improves. Fixed long durations don’t account for individual safety and symptom limits, especially with upper-body work, so they’re less appropriate as universal guidelines.
