The reason behind football players spitting on the pitch has been revealed.
A study by the International Journal of Sports Nutrition and Exercise Metabolism shed light on why players often spit on the field.
The practice is known as carb rinsing and involves swishing a carbohydrate-rich solution in the mouth and expelling it instead of consuming it.
Cristiano Ronaldo, Kylian Mbappe, and Harry Kane are often seen doing this.
Fans often wonder why these players and many others spit on the pitch and now the study reveals it is a technique athletes use in sports to keep energy up.
