Which statement correctly describes the relationship between speed and strength?

• A. Speed combined with strength provides power and force.
• B. Speed alone determines performance, not strength.
• C. Strength alone determines power.
• D. Speed and endurance together produce power.

Answer: (A)

Power comes from combining how much force you can exert with how quickly you exert it. In biomechanics, power is defined as force times velocity. Strength supplies the force you can generate, while speed determines how fast you apply that force. Put together, they produce a higher power output than either alone. If you only have speed, you can move fast but may not push with enough force to create much power. If you rely only on strength, you can push hard, but doing it slowly reduces the power you generate. Endurance affects how long you can maintain effort, not the immediate rate of doing work, so it doesn’t define power in the same way.
