Why Do Footballers Spit Out Their Drinks?
It's not uncommon to see some football players take a sip of water or sports drink and spit it out during matches, without swallowing. This behavior, which might seem odd at first glance, may not be solely related to thirst. Some football players might swish carbohydrate-rich liquids in their mouths and spit them out, aiming to gain a slight performance advantage.
The method of carbohydrate cycling could be in use.
The goal of the carbohydrate rinsing method is not to directly provide energy to the body; rather, it's to stimulate the brain by utilizing the perception of carbohydrates in the mouth. According to Live Science, athletes using this method can swish a carbohydrate-containing liquid in their mouths for about 5-10 seconds.
Some research suggests that this method could slightly improve performance in high-intensity exercises lasting approximately an hour or less. Experts estimate that this increase could be around 23%.
The exact workings of this method are not entirely clear. However, one possible explanation is that the carbohydrate receptors in the mouth stimulate certain areas of the brain. It is believed that this stimulation could potentially affect movement performance or the perception of effort.
Not swallowing the drink can soothe the stomach.
Another reason why football players might spit out their drinks could be to avoid upsetting their stomachs. Consuming excessive fluids or drinks high in carbohydrates during a match could potentially lead to stomach issues for a player who is running at a high pace.
Especially when the drink is very concentrated, the stomach may need more fluid to dilute it. This could mean added weight, discomfort, or stomach problems for the athlete. Therefore, some players might prefer to merely swish the fluid in their mouth and spit it out rather than swallowing it.
However, the effectiveness of this method in football remains a subject of debate.
Most studies have been conducted in a laboratory setting, primarily focusing on sports like cycling or running. Therefore, the impact of carbohydrate rinsing in a variable-paced and long-duration game like football remains unclear.
Nevertheless, the method is practical, easy to implement, and may not pose a significant disadvantage in short-term trials. Consequently, some football players may aim to avoid straining their stomachs and gain a slight mental/performance boost by spitting out the drink during the match.
