An agility task may be hest described as a rapid, whole-body change of direction or speed in response to a stimulus (Sheppard and Young, 2006). Many other approaches to defining agility have focused on the physical requirement only, generally a whole-body direction change (Fulton, 1992; Rigg and Reilly, 1987; Tsitskarsis, Theoharopoulus and Garefis, 2003). The unique distinction between the definition used by Sheppard and Young (2006) and other previous definitions is the inclusion of reaction to a stimulus, rather than just change-of-direction speed (COOS). Put simply, agility is an open skill, and COOS is a closed skill. Closed skills can be precisely pre-planned, whilst open skills involve movements that are composed in response to circumstances in the environment (stimuli), such as the movement of a competitor or the bounce of a ball.
