The influence of Carbohydrate-Electrolyte Ingestion on Soccer Skill Performance

It has been proven that soccer players do most of their work at a rate equivalent to 70-80% VO2 max. At these levels glycogen becomes the main source of energy. Low glycogen concentrations in muscles have been associated with a lower work rate on the soccer field. The importance of hydration before, during and after physical activity has been proven over and over again. Knowing that glycogen is the primary source of energy, it has been determined that hydrating and replenishing carbohydrates and electrolytes at the same time is key.
Studies have shown that athletes who ingested a carbohydrate-electrolyte mix are able to sprint faster. This suggests that the athletes would be able to sprint to the ball faster and still have enough energy to accurately pass or shoot the ball. Thus, the athlete would appear to have improved performance. This has only been shown in athletes who began with a reduced glycogen level.
