Power is the fitness skill associated with the rate at which strength can be used.

Power is indeed defined as the ability to exert force quickly, which relates directly to the rate at which strength can be applied. In fitness and sports contexts, power is crucial because it allows an individual to perform movements that require both strength and speed, such as jumping, sprinting, or lifting weights explosively. This skill is integral to athletic performance, as many sports demand that athletes generate maximum force in minimal time. Thus, understanding that power combines both the aspects of strength and the rate of force application is fundamental to skill-related fitness.
