At present, no agreement on a precise definition of agility within the sports science community exists. The term is applied to
a broad range of sport contexts, but with such great inconsistency, it further complicates our understanding of what trainable
components may enhance agility. A new definition of agility is proposed: ‘‘a rapid whole body movement with change of
velocity or direction in response to a stimulus’’. Agility has relationships with trainable physical qualities such as strength,
power and technique, as well as cognitive components such as visual scanning techniques, visual scanning speed and
anticipation. Agility testing is generally confined to tests of physical components such as change of direction speed, or
cognitive components such as anticipation and pattern recognition. New tests of agility that combine physical and cognitive
measures are encouraged.
