TOUCHES MADE (successful and unsuccessful)
3: Touch football involves the use of all three energy systems which are the ATP-CP system, Lactic Acid system and the Aerobic system. ATP stores are fully replenished after 2-3 minutes or 50% can be replenished after 30 seconds. The ATP-CP system is anaerobic which means there is no oxygen present and is a result of the breakdown of creatine phosphate. It is predominantly used in activities which are high intensity and last for up to 10 seconds. There are no fatiguing by products however ATP production is very limited.
The lactic acid system is also anaerobic however it lasts for around 90 seconds. It is the result of glucose being converted into lactic acid.
Lactic acid is a fatiguing by product that builds up in the body after vigorous exercise and which force an athlete to slow or stop their activity. The final energy system is the aerobic system. This is the production of energy from the breakdown of carbohydrates and fats using oxygen. This system is used for low intensity activities of a long duration. The bi-products of this system are water, carbon dioxide and heat however they are not fatiguing which is why the aerobic system is efficient for long duration and endurance events.
A game of touch requires the use and interplay of all three energy systems; ATP-CP, Lactic Acid and Aerobic systems. The body simultaneously uses an energy system as there are many skills in touch that are of different intensities and duration. For roughly the first 2 minutes of the game, the intensity is...
