There are three main energy routing systems through which the body uses the energy needed to perform various activities. One of the phosphate energy pathways that uses creatine phosphate (CP).
ATP production rate is very fast. CP is important for its remodeling after ATP breaks down during energy release. The muscle does not have much CP storage and therefore it is limited in supply, however, it is readily available at the start of an activity.
It is commonly used in activities such as gymnastics and weightlifting. The other system is anaerobic glycolysis, which does not require oxygen. It produces faster ATP for operations that require large amounts of energy in a relatively long period of time
East. Free hand exercises. Other pathways include the phosphine pathway (which uses the instant source) and the aerobic route (which uses fat or carbohydrates).
In the case of a marathon, the aerobic energy path will power the runner.
