Types of Speed
Perceptual. This involves quickness in perceiving an incoming attack or an opening for your attack. Vision is the primary sense used, but the other senses may also be used, such as the opponent making an unconscious noise before an attack.
Mental. This is the rapid ability to select the correct attack, block, movement, or fighting strategy, and to make changes to them.
Movement. This is the ability to quickly move the arms, legs, or body, and change their direction, or stop their movement.
