How is muscle power best defined?

Muscle power is best defined as the ability to move a weight or overcome resistance. This definition emphasizes the combination of strength and speed, which is essential for generating force rapidly. Power is critical in various physical activities, such as sprinting, jumping, or throwing, where not only the amount of force generated is important, but also how quickly that force can be applied.

In physical training, workouts aimed at improving muscle power typically involve exercises that require explosive movements, which contribute to the overall athletic performance by enhancing both strength and quickness. The other options focus on different aspects of fitness; for instance, flexibility and endurance do not directly pertain to the rapid force generation characteristic of muscle power, and performing high repetitions tends to relate more to muscular endurance rather than power itself.
