Answer:
The ATP-PC system is a very short-term energy system that can only provide energy for a few seconds. It is fueled by the breakdown of ATP and creatine phosphate (CP) in the muscles. Activities that are primarily fueled by the ATP-PC system include:
* Sprints
* Weightlifting
* Burpees
* Any other activity that requires a sudden burst of energy
The anaerobic system is a short-term energy system that can provide energy for up to about a minute. It is fueled by the breakdown of glucose without oxygen. Activities that are primarily fueled by the anaerobic system include:
* Short-distance running
* High-intensity interval training (HIIT)
* Any other activity that requires a sustained burst of energy
The aerobic system is a long-term energy system that can provide energy for hours. It is fueled by the breakdown of glucose and fat in the presence of oxygen. Activities that are primarily fueled by the aerobic system include:
* Long-distance running
* Cycling
* Swimming
* Any other activity that requires sustained aerobic activity
