Caffeine Can Enhance Athletic Performance According to scientists at the University of Birmingham, athletes can benefit from intake of caffeine while providing a performance as it stimulates the absorption of carbohydrates by the human body. The study was conducted by researchers at the University of Birmingham’s school of sport and exercise sciences.

It was found during the investigation that the caffeine in sports drinks could increase the absorption of carbohydrates by as much as 26 percent, leading to a sharp advantage for athletes while participating in professional events.

Dr. Asker Jeukendrup, the director of the University’s Human Performance Laboratory, said that if an individual can obtain energy from his or her drinks then he or she is using less energy from the body stores.
