Carbohydrates are the main energy source for our body. Along with fat and, in small part, with proteins, they provide us with the energy needed to carry out daily activities including sports. In particular, carbohydrates play a crucial role during long-duration activities. The intake of carbohydrates with foods during an effort may require too long digestion times, subtracting energy to other physiological processes. This generated the need to supplement the normal diet with carbohydrates through supplements (maltodextrins).
