Which time duration is commonly recommended across asthma, CF, and PD guidelines?

• A. 15 to 30 minutes.
• B. 30 to 60 minutes.
• C. 60 to 90 minutes.
• D. 90 to 120 minutes.

Answer: (B)

Regular aerobic activity is commonly emphasized in asthma, CF, and PD guidelines because it improves exercise tolerance, lung efficiency, and overall well‑being. The 30–60 minute range per session hits a practical balance: it’s long enough to provide meaningful cardiovascular and pulmonary benefits, such as better endurance and energy expenditure, while staying feasible for most patients to fit into a weekly routine. Shorter bouts (15–30 minutes) may not accumulate enough stimulus to produce lasting improvement, while longer sessions (60–90 minutes or more) can be harder to sustain, potentially increasing fatigue or dyspnea for some individuals. Because guidelines often encourage most days of moderate activity, this 30–60 minute window serves as a realistic, effective target across these conditions.
