1 Comparing the three energy systems 1) ATP-PC within the body's muscle mass there are between 570-690 millimoles of ATP and PC. Which provide 15 – 20 kilojoules of useful ATP energy

2 Lactic acid system Can potentially resynthesise 3 moles (3000 millimoles ) of ATP from 1 mole of glycogen. If all 180 grams of glycogen were broken down, 180 grams of lactic acid would be formed. Since the muscles and blood can tolerate only 60-70grams of lactic acid before fatigue sets in. This system produces about twice as much energy as the ATP-PC system

3 Aerobic system Following hundred of complex chemical reactions, yield a total of 38 moles of ATP from the breakdown of 1 mole of glycogen. A further 80 – 100 grams of glycogne is stored in the liver. Provided exercise intensity is submaximal approx 13 times the amount of energy can be released aerobically as is possible anaerobically.

We need a constant supply of energy, even at rest. During exercise more energy will be required. The energy needed will vary with the demands of the activity.
