Excersise physiology - energy systems explained, eg lactic acid etc
Describe each of the energy systems
*ATP-CP (phosphogen) System
Stored at the myosin cross-bridges is broken down to release energy for contraction it is used for short bursts of energy - it is exhausted after about 10 seconds.
*Lactic Acid System
Carbohydrate is broken down anareobically (without oxygen) to lactic acid. This causes muscular fatigue. The energy released during this breakdown is used to re-synthesize A.T.P. Exercise performed at maximum rates for between one …

…muscles. This is called anaerobic respiration (without oxygen).
*Lactic acid (in large amounts) is usually formed during strenuous exercise, and a large amount of lactic acid in muscle leads to fatigue and can cause muscle cramps.
*Lactic acid also causes the souring of milk, by fermentation of lactose. This makes Lactic acid useful commercially, as it is used in preparing cheese, sauerkraut, soft drinks, and various other food products.
