Answer:
Like most mammals, you generate energy via three systems: phosphagen (ATP-PC), glycolytic, and oxidative (see figure 2.1). All three energy systems are engaged during all forms of physical activity. However, the extent to which each one is involved varies depending on the duration and intensity of the activity.
Anaerobic Alactic (ATP-CP) Energy System (High Intensity – Short Duration/Bursts) ...
Anaerobic Lactic (Glycolytic) Energy System (High to Medium Intensity – Uptempo) ...
Aerobic Energy System (Low Intensity – Long Duration – Endurance)
