Which term describes the ability to exercise for long periods of time?

• A. Endurance
• B. Cardiovascular Fitness
• C. Muscular Strength
• D. VO2 max

Answer: (B)

Endurance is the ability to sustain physical activity for a long time, even as fatigue begins to set in. When you exercise for extended periods, your body relies on a steady supply of oxygen to the muscles, which depends on your heart and lungs working efficiently. That overall capacity to keep going is what we call endurance. Cardiovascular fitness describes how efficiently the heart, lungs, and circulation can deliver oxygen to the body during activity and recover afterward. It supports endurance, but the term that directly describes the ability to exercise for extended periods is endurance. Muscular strength is about how much force a muscle can produce in a single effort, not how long you can continue, and VO2 max is the maximum rate of oxygen uptake, a measure within cardiorespiratory capacity rather than the general ability to last longer.
