Agility is essentially a combination of acceleration, deceleration and changing direction.
To create fast, multi-directional movement, you need to teach your body
to move, challenging your central nervous system to adopt a movement pattern
and perform it successfully. For example, when you first ride a bike you
need strength to move the pedals but you also need to 'learn' the movement
pattern.
Once it's learnt correctly it will be stored in what may be termed 'muscle memory.'
Rugby related movements are complex combinations of smaller, simpler movements. The reason some players, like Jason Robinson, are better at performing certain movement skills is that they more easily bring together all the smaller movements and co-ordinate them. These movements are:
Breaking agility down into it's components and training
them independently is the first step, followed by a progression to combination
drills.
