You might have noticed a lot of players spitting out their water at the World Cup.
They could be rinsing out their dry mouths, but scientists think they might be doing something called “carb rinsing.”
This is where you swirl a carbohydrate solution around your mouth to trick your body into thinking energy is coming.
This way you may give your brain a boost to stay alert.
It isn’t common practise yet, but sports scientists believe the technique is on the rise.
Football fans were heartbroken all over England on Wednesday night. The team was beaten by Croatia in the World Cup semfinals in Russia, leading everyone across the nation to accept the fact it’s not coming home — not until 2022, anyway.
Looking back on the memories of the World Cup that wasn’t to be, you might remember seeing a lot of spitting. Not just normal spitting, but players rinsing their mouths out with water and producing a stream of water, rather than drinking it.
England’s captain Harry Kane seemed to do this a lot, squirting water from his bottle into his mouth only for it to come back out again — as did midfielder Dele Alli, and Portugal’s Cristiano Ronaldo.
According to the New York Times, this could be a fitness technique called “carb rinsing.” Drinking a lot of water can lead to bloating, so it makes sense for players to wash their mouths out without swallowing if they are feeling dry. But carb rinsing is where you wash your mouth out deliberately with a carbohydrate solution, which essentially tricks your body into performing better.
It works by receptors in the mouth sensing the carbs and sending signals to the pleasure and reward centers of the brain, saying there is more energy on the way. This makes the muscles work harder, without the negative effects of carbohydrate drinks like stomach heaviness and cramps.
The England team didn’t discuss its nutritional tactics at the World Cup, the NY Times says, but a source familiar with the team’s regimen said carb rinsing was “standard practice.”
A study published in 2017 in the European Journal of Sport Science found that carb rinsing boosted performance in a range of activities. The research team from Coventry University tested 12 healthy men in their 20s, and found after carb rinsing they could jump higher, do more bench presses and squats, sprint faster, …read more
