Taking on carbohydrates during exercise is a well-described way to help fuel muscle and endurance. But the research in this area took a decidedly strange turn some years ago when it was shown that the simple act of just swishing a carbohydrate-containing drink in your mouth for a few seconds can also have a performance advantage. This was research that I simply could not believe when I first came across it, but it has been replicated many times now. In this podcast, I’ll look at just how carbohydrate mouth rinsing can improve sports performance.
