A scientific nutrition strategy improves time trial performance by ≈6% when compared with a self-chosen nutrition strategy in trained cyclists: a randomized cross-over study. In a laboratory study, we have examined whether a controlled delivery of food improves performance over the own strategy of athletes. If the athletes got the food checked according to schema, the performance in a time trial after a permanence burden was significantly improved while the athletes who nourished on their own fists, poor sections.
