Early experiments showed that adrenaline increases twitch, but not tetanic force and rate of force development in muscles. [38]One proposed explanation is Tim Noakes' "central governor" theory, which states that higher instances in the central nervous system dynamically and subconsciously control the number of active motor units in the muscle.

Adrenaline, also known as epinephrine, is a hormone and medication [10] [11] which is involved in regulating visceral functions (e.g., respiration). [10] [12] It appears as a white microcrystalline granule. [13] Adrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata. [14]
