Speed and coordination are one of the main fitness components, important for success in many sports.
Speed is not just how fast someone can move, but is dependent on their acceleration (how quickly they can accelerate from a stationary position), maximal speed of movement, and also speed maintenance (minimizing deceleration). Movement speed requires good strength and power.
Coordination is, in essence, the ability to integrate all the components of fitness so that effective movements are achieved. Rhythm, spatial orientation and the ability to react to both auditory and visual stimulus have also been identified as elements of coordination.
