Which activity is listed as aerobic cardiovascular fitness?

• A. Sprinting
• B. Weightlifting
• C. Walking
• D. Chess

Answer: (C)

Aerobic cardiovascular fitness comes from sustained, rhythmic activity that uses large muscle groups and keeps the heart rate elevated with oxygen-fueled energy. Walking fits this well because a brisk, continuous walk can be maintained for extended periods, directly training the heart and lungs to deliver oxygen to working muscles. Sprinting, while great for speed and power, relies mainly on anaerobic energy for short bursts, not the steady oxygen-using system. Weightlifting focuses on short, intense efforts and muscle strength rather than sustained aerobic endurance. Chess involves minimal physical activity and doesn’t engage the aerobic system. So walking is the activity that best represents aerobic cardiovascular fitness.
