Power is a term used in physical fitness to describe the ability to exert maximal force in as short a time as possible, as in accelerating, jumping, and throwing implements. Power is proportional to the speed at which you can apply maximal force, while strength is the maximal force you can apply against a load. Power is important in sports because it is a reflection of the bodys energy production, applied to generate output of some kind, from a pedal revolution to a vertical jump. Power training involves the development of force, velocity, or both to shift the force-velocity curve to the right, meaning more force for a given velocity or the same force for a lower velocity. Power training can include lifting weights, throwing implements such as medicine balls, running against resistance, and plyometrics.

In summary, power is a crucial component of physical fitness, especially in sports that require quick and explosive movements. Power training can help improve an individuals ability to exert maximal force in a short amount of time, leading to higher velocities against a given load.
