Football is not only a physical activity but it also allows to learn tactics and serves. A player is forced to take immediate decisions and predict moves of the rival. The game demands a high level of focus, creative thinking and brilliant evaluation of given situation. Dehydration, time constraints (a lot of trainings/extra classes) can impede proper energy and nutrients supply and as a consequence may lower effectiveness of your game. The sooner you develop the proper conscience of nutrition, ability to deal in difficult situations as well as time management, the better you will cope in the field, regenerate faster and prepare yourself for the next training.
