Briefly explain the three main sources of energy available during exercise and when they are used.
What will be an ideal response?
(1) ATP-CP energy system-suited for extremely short bouts of activity, such as jumping, throwing, lifting, or sprinting. Any sudden burst of energy that lasts no more than about 10 seconds will use this system, which relies on stored ATP and creatine phosphate in the muscle to deliver energy. (2) Glycolytic energy system-energy comes through ATP generated through glycolysis. Because this system has the potential to produce lots of lactic acid and is inefficient at generating ATP, it is best suited for activities that last less than 90 seconds. (3) Aerobic energy system-responsible for most of the body's energy production, which takes place in the mitochondria and requires glucose and oxygen. This system allows for longer, sustained exercise.
