Stay Fit, Stay Young: Mitochondria in Movement: The Role of Exercise in the New Mitochondrial Paradigm

Figure 3

The energy systems that contribute to sport practice. The phosphagen system (ATP-CP) is used in explosive movements (Immediate energy). Anaerobically created energy overlaps with use of the ATP-CP system to provide energy for activities lasting up to around 3 minutes. Aerobic glycolysis provides energy for longer-distance events by breaking down fat and some carbohydrates.
