Power is defined as?

Explanation:
Power is about how quickly work is done. Work equals force times distance, so power equals work divided by time. Since distance over time is speed, power = force × speed. This means a muscle shows high power when it can generate a strong force quickly. The other ideas refer to different concepts: oxygen uptake relates to aerobic capacity, maximal force is strength, and range of movement is flexibility. Power is measured in watts, reflecting the rate at which work (force over distance) is performed.
