Which statement best defines power?

• A. The combination of strength and speed.
• B. The ability to transfer energy into force rapidly.
• C. The rate of maintaining balance during movement.
• D. The ability to sustain movement for extended periods.

Answer: (A)

Power in athletic movement comes from generating force quickly, which happens when you combine how much force you can produce (strength) with how fast you can apply it (speed). The statement that power is the combination of strength and speed best captures this idea, because it directly ties producing a large force to doing it rapidly. In training terms, movements that are heavy and performed rapidly yield higher power.

The other ideas describe related qualities but not power itself: maintaining balance during movement is about stability, sustaining movement describes endurance, and the phrasing about transferring energy into force rapidly is a physics-style description that doesn’t as clearly connect to the practical, performance-focused concept of power.
