While most spitting by individuals is uncalled for and unsanitary, it seems that there is a hidden purpose that it is often done by elite athletes. A member of a team will take a mouthful of liquid, rinse and then instead of swallowing spit it out. They choose a particular sports drink recipe which is usually their own concoction. Reluctant to discuss the ingredients, this technique is known as “carb rinsing” or “mouthing washing”. After a decade of research it has been discovered that athletes can gain an edge or boost in performance by rinsing with a carb solution. Messages are sent to the brain that there is extra energy being ingested and this in turn allows the muscles to push further. The 10 second process can increase performance by as much as 30 Minutes. It is the oral receptors in the mouth receiving signals that carbohydrates are being ingested. This is a way of simply tricking the brain into thinking it is receiving more energy. However, this can have its limits in which the body will actually need carb intake. Not beneficial or acceptable when performed on subway platforms or while walking in the street.
