© Chris Hudd & Edrolo 20173Theory summaryThe three energy systems work together to supply the energy required to resynthesise ATP. Their relative contribution is determined by the intensity and the duration of the exercise.The energy systems' role in energy productionRecap:The energy systems are responsible for providing the energy to resynthesise ATP from ADP and Pi.

Energy is produced at an explosive rate due to the simple anaerobic chemical reactions that take place.The system is limited by the amount of Creatine Phosphate stored in the muscles.The ATP-CP system

© Chris Hudd & Edrolo 20177Theory summaryThe anaerobic glycolysis energy system produces energy by partially breaking down Glucose anaerobically (no oxygen).Energy is produced at a fast rate due to the simple anaerobic chemical reactions that take place. When compared to the ATP-CP system, this process is more complex as it requires a greater number of steps.The system is limited by the accumulation of hydrogen ions (H+) that are by-products of the process.Anaerobic glycolysis
