Thanks to everyone who gave me some advice on my query regarding the
biomechanics of agility performance.

In particular, thanks to Jean-Francois Stein who got me thinking
about other ways of describing agility, and how it is not really used
as a word in the scientific literature (e.g. one that can be searched
for in Medline), even though its use is very common amongst physical
conditioners. Thanks also to everyone else but particularly Michael
Yessis, Sharon Bullimore and Gabe Fendley who suggested a number of
articles / books.

For other people who may be interested, there appear to be numerous
articles that use the term "cutting". I have attached some of these
to the reference list below.

Therefore, I should have defined agility in my request as something
along the lines of:

"The ability to change direction while maintaining speed".

Some information which I have found useful was that of a chapter in a
book titled High performance Sports Conditioning, in that it discusses
the multi-factorial nature of agility performance.

(ed) High-Performance Sports Conditioning. Human Kinetics, Champaign,
IL, pp 139-165
