Adrenaline is a breakdown product of Noradrenaline. Adrenaline is a hormone which is produced by the adrenal gland in the body. Tt is produced in periods of high stress or physical activity. When the adrenal gland produces adrenaline, it causes as increase in heart rate, also dilating blood vessels and air passages. This allows for an increased volume of blood to be pumped around the body at one specific time. Also as air passages are dilated, it allows for more oxygen to be breathed in at one time; thus providing the body with more energy, and similarly allowing more Carbon Dioxide; the waste product of respiration to be exhaled at one time. Therefore it is useful during exercise as the muscle require more energy; provided by oxygen during this time. The reaction from adrenaline being produced is improved performance for short amounts of time.

What is the effect of caffeine on the brain?
It causes the adrenal glands to produce adrenaline. This release of adrenaline causes a faster heart rate, opening up of breathing tubes, release of sugar into the bloodstream from the liver, tightening of muscles, an increase in blood flow to muscles. Other effects include an increase in dopamine levels.
What are the short term effects of exercising on blood flow?
