This is a scene that we see repeatedly on professional football pitches, and the 2018 World Cup in Russia is no exception: players who rinse their mouths and spit the liquid underneath
they want to refresh their mouths, which tends to dry up – as it happens to anyone – after prolonged periods of physical activity.
But scientific research suggests that rinsing can have a positive effect on the performance of athletes. 19659003] In particular, take a sip of a solution with carbohydrates, rinse the mouth and then spit out the liquid is a technique that has been tested in the past.
The researchers studied whether this allows the athlete to gain energy in times of fatigue such as the last decisive minutes of a football match or overtime. [196] 59003] The various studies that badyze it in football have not yet conclusive results, but some indications have shown that the mouthwash containing carbohydrates, known in English as carbohydrates, can be positive
– – The desired pulse —
One of the studies in this field is that of researchers from the University of Coventry, UK, published the # 39, last year in the European Journal of Sports Science.
Experts found evidence that rinsing the mouth with carbohydrates helps improve performance, although its impact becomes more evident in physical activity instantly
This coincides with Trent Stellingwerff, the director of performance solutions at the Sports of Canada Institute and author of another study on the subject
The results of the research carried out "have affected us", recognized Stellingwerff.
"Rinsing has an immediate effect, since we can see that the exercise that is being done is easier ", explains in the conclusions of his research.
The difference between ingesting carbohydrates and only rinsing with a solution that contains them based on the benefits and effects that they produce on the body.
While it is recommended to consume before or after physical activity to generate the energy reserves necessary to activate the muscles, rinsing is more oriented toward instant stimulation
L & rsquo; Study of the British University of Coventry and Stellingwerff confirmed that the mouth contact with a carbohydrate substance " stimulates the centers of pleasure and reward in the exercise. Brain which provides a positive message to the body to convince it unconsciously that more may be required.
The reason why sport They spit and do not ingest it, that is, in the case of doing so, it could create stomach problems in a body that is to the limit of physical effort.
— Stimulation of the nerves —
Studies explain that the person has to maintain the fluid between 5 and 10 seconds so that he can have a contact with the most large number of receptor-related nerves in the brain-related mouth, also affecting brain motivation and tolerance. Pain
Footballers and their medical teams are often reluctant to explain the techniques that they use to improve performance.
However, the New York Times quoted a source in the England team as acknowledging that the rinsing of carbohydrates was "something that the team had seen doing in the past", which which is considered "a fairly common practice".
While the investigations are still in a preliminary stage ] the results obtained suggest that this method can improve the person's performance between 2% and 3% for a period of time between 15 and 30 minutes.
It is enough that marks the difference between success and failure for an elite athlete or, simply, to reach the goal in the case of an athlete amateur.
