Describes the biochemical processes involved in energy provision for different sports events and the way in which limitations in the energy supply can cause fatigue and thus limit performance.

'The great strength and appeal of this book is that it beautifully brings together, like a seamless garment, the performance, the physiology and the biochemistry of the main different categories of sport, involving respectively strength, power, speed, endurance and multiple sprint game sports...this is a superb book - totally readable, highly relevant interesting view of biochemistry as defined by patterns of sporting activity. Ron Maughan and Mike Gleeson are to be very warmly congratulated - and thanked for filling a major gap'. N.C. Craig Sharp, Professor of Sports Science, Brunel University 2004.
