Which factor is used to decide if outdoor workouts should be canceled due to air conditions?

• A. Altitude
• B. Air quality
• C. Cold weather concern
• D. Recommended facility temperature

Answer: (B)

Air quality determines safety for outdoor workouts because exercising increases breathing rate, which means more air—and more pollutants—are drawn into the lungs. If the air is polluted, smoky, or has high ozone levels, this can irritate the airways, trigger asthma symptoms, and impair performance. That’s why air quality is the key factor used to decide whether to cancel outdoor sessions.

Other factors—like altitude, which affects oxygen availability at higher elevations; cold weather concerns, which relate to temperature and wind chill; or the recommended indoor facility temperature—don’t address the safety of breathing in polluted outdoor air, so they’re not the primary basis for canceling based on air conditions. When air quality is poor, it’s wise to cancel or move activities indoors until conditions improve.
