Power is defined as Work per unit of time:
Power = Work / time
P = W / t
From earlier discussion, Work is the product of Force and Displacement. Thus Power is writable as rate of force production:
Power = (Force × Displacement) / time
P = (FD) / time
simplified,
Power = (mass × acceleration × Displacement) / time
P = maD / t
Power is speed born from effortless movement that exists in biomechanical low friction / bioelectrical low interference environments.
A Deeper Meaning of Power
Both Work and Power contain components that indicate efficiency. Acceleration within the equation for work requires a component of efficiency because of its time element. Power is Work per unit of time, making Power logarithmically greater a measure of efficiency than Work.
Movement through space is more than efficiency of the kinetic chain. While it is kinetics, efficient movement requires a guidance system to navigate terrain, obstacles, and waypoints. Locomotion without steerage is useless.
The kinetic chain is a guidance system for our behavior in space as well as a way to move through it. It is a navigation and orientation of a locomotive complex. Movement then applies to all behavior, volitional, non-volitional, conscious and unconscious.
Optimal movement requires optimal behavior from the biomechanical and bioelectrical systems. It therefore demands identical behavioral quality from all perspectives, be they metaphysical, psychological, or social.
