Endurance is a health-related physical fitness component associated with which capability?

• A. Explosive power
• B. Sustained physical activity
• C. Quick reaction time
• D. Maximal strength

Answer: (B)

Endurance in health-related fitness is about how long you can perform a task or sustain a level of effort. It’s the capacity to keep moving, breathing, and working muscles over an extended period. That’s why the best match is sustained physical activity—endurance lets you participate in activities like running, cycling, or swimming for longer durations without tiring quickly.

Explosive power is about short, powerful bursts of effort; quick reaction time is about how fast you respond to a stimulus; maximal strength is about the greatest force a muscle can produce in one effort. Each of these reflects different abilities, whereas endurance centers on continuing activity over time.
