While the world is watching with interest the ongoing FIFA 2022 matches Globalism In Qatar, images of soccer players spitting on the ground during matches are common. But why do they do this?

According to experts, there is some science behind this.

Some sports punish players for spitting, such as basketball and tennis, but football and rugby do not, so players have the freedom to be phlegmatic.

science behind it

Spitting is a common practice in football. It turns out that there are some science and performance optimization factors behind this, rather than just players expressing their dissatisfaction with the situation.

Studies have shown that exercise increases the amount of protein secreted in saliva, particularly a type of mucus known as saliva MUC5B. This causes the saliva to thicken, making it more difficult to swallow. As a result, there are numerous photos of soccer players spitting, even though it looks disgusting.

According to Dr. Udit Kapoor, Senior Consultant at Asian Hospital, Faridabad, the saliva in the mouth gets thicker during strenuous physical activities like football matches, which players prefer to spit out, Indian Express reports. “Thick saliva makes swallowing more difficult. As a result, it is better to spit it out.”

He went on to say that not only footballers spit, but also cricketers and rugby players – this is legal in sport. Former Nigeria goalkeeper Joseph Dosso said footballers spit because they “need something to clear their throat… they run 10 to 15 yards and they need air to breathe,” Firstpost reported.

There are some other theories about the prevalence of spitting in football. Some think it’s a case of obsessive-compulsive behavior, while others think it’s a masculine symptom intended to scare.

There were also images of players such as England’s Harry Kane forcefully squirting a drink into his mouth and then spitting his mouth full on the nearest patch of bare ground since the start of the World Cup.

However, there is an explanation for this activity, which is known as carb flushing, Firstpost explains. Filling your mouth with a carbohydrate-laden liquid, in this case a sports drink high in sugar and salt, activates the pleasure and sensation receptors in your brain, making it think that extra energy in the form of food is on the way. This, in theory, prevents your brain from thinking your body is tired.

Asker Jeukendrup, exercise physiologist and sports nutritionist, previously told The New York Times that the practice is like “a little brain trick.” In fact, it was discovered that carb rinsing made cyclists about 1 minute faster at 40 kilometres. Cycling time trials in a 2004 study with the University of Birmingham.

Others in the field have also embraced the benefits of carb rinsing. Dr. Sourav Poddar, MD, a sports medicine physician, states that carb rinsing can improve performance by two to three percent.

Another study published in 2017 in the European Journal of Sport Sciences found that rinsing carbs improved performance. The study looked at 12 healthy men in their 20s and discovered that after rinsing down the carbs, they could jump higher, do more bench presses and squats, run faster, and be more alert.
