Sportsmen who exercise for about an hour often rinse their mouths with this solution.
In 2014, American scientists analyzed data from 11 previous studies on gargling with carbohydrate solutions. The results showed that carbohydrates in the mouth activated certain areas of the brain, thereby improving motor function, helping players increase performance by 2-3%. Furthermore, the carbohydrate solution contained sweet-tasting glucose or maltodextrin, a colorless and tasteless food additive. The sweet taste in the mouth made the drinker feel more motivated.
Dr. Michael Joyner, a physiologist at the Mayo Clinic in Rochester, Minnesota, saidMost studies on carbohydrate gargling to date have been conducted in the laboratory and focused on cycling. The effect of carbohydrates on intense soccer matches is not yet known. However,Rinsing with this solution is a practical, accessible method with few drawbacks, which athletes can freely experiment with.
Players do not swallow carbohydrate liquids to avoid digestive problems, although the act of rinsing and spitting them out strikes many as unhygienic.Doctors recommend that players should only rinse their mouths for 1-2 hours during a match. This method should not be used during practices lasting longer than 2 hours.
