While the parasympathetic system controls the rest and digests requirements of the body, the sympathetic system is in charge of the fight or flight responses and during intense physical exercise (Kelly, 2004).

The Epinephrine is produced to improve the performance of the physiological effects that occur (Kelly, 2004).
