The scientists have always known that caffeine combined with carbohydrates can increase endurance. But only now they were able to prove how this combination affects the effectiveness of training.
A research team from Sheffield Hallam University asked eight volunteers to play three football games in order to assess the quality of the game. For the first time, the volunteers had a drink without caffeine. Before the second game, they were offered a caffeinated beverage, and before the third game they had a drink containing a mixture of caffeine and carbohydrates.
That last drink resulted in improving the volunteers’ performance during the game. Mayur Ranchordas, the author of the study, says that caffeine itself is able to improve one’s performance, but only for a short period of time. But adding carbohydrates can increase the endurance for more than an hour.
