Which term describes the ability to perform activities for an extended period of time?

• A. Cardiovascular Endurance
• B. Aerobic
• C. Isokinetic Exercise
• D. Flexibility

Answer: (A)

Cardiovascular endurance describes the body's ability to sustain aerobic activity for an extended period. It depends on how efficiently the heart, lungs, and circulatory system deliver oxygen to working muscles and how effectively those muscles use that oxygen over time. This makes it the best term for activities you perform for longer durations, like running, cycling, or swimming for several minutes or more. The other terms describe different concepts: aerobic refers to the type of activity that uses oxygen to produce energy, which supports endurance but isn’t the capacity itself; isokinetic exercise is a type of resistance training at a constant speed focusing on strength and neuromuscular control; and flexibility is about the range of motion around joints, not duration of activity.
