Which combination defines the Moderate risk category in this framework?

Which combination defines the Moderate risk category in this framework?

• A. Fewer than two risk factors, no medical exam, VO2 40-60%
• B. Two or more risk factors, medical exam, vigorous >60% VO2
• C. Known cardiovascular disease with medical clearance
• D. At least three risk factors with no exercise limits

Answer: (B)

In this framework, how risky a person is depends on the number of risk factors and whether there’s a requirement for medical clearance before exercising at higher intensities. Moderate risk applies to individuals with two or more risk factors (or known disease) who should obtain medical clearance before engaging in vigorous activity. This option reflects that: having two or more risk factors, needing a medical exam, and performing vigorous work defined as greater than about 60% VO2. The medical clearance requirement before pushing into vigorous intensity is the hallmark of the moderate-risk category. The other descriptions align with either lower risk (fewer risk factors, no exam) or scenarios that don’t fit the moderate risk pathway (known disease with clearance or those lacking clear guidance about clearance for vigorous exercise).
