Energy is needed for bodily functions, both voluntary and involuntary. Primarily, energy is stored in 3 forms and each has their own system of use. ATP is stored in the muscle and is in a minimal supply, used mainly for fight or flight reactions. Then there is aerobic and anaerobic, with the key difference being that one requires oxygen and one require just glucose and lactate. When doing strenuous activity, all three types are used.
- Whether we are sleeping or awake, our bodies need energy for its basic functions like vision, eating, sleeping, thinking, breathing, and digesting.
- When we step on a block to engage in swimming, we are about to demand energy from our body at a high rate.
- The energy the body uses to perform its functions are in the form of adenosine triphosphate (ATP). ATP is energy to our muscles as gasoline is to cars.
“We have three sources of providing energy for our muscles; stored energy, the anaerobic system and the aerobic system.”
