Nutrition
Nutrition also is an important factor in any sport. A proper pregame meal can give you more energy during a match. Eating carbohydrates in the hours preceding a game will provide your body with an easily utilizable source of energy, but meals full of fat should be avoided because it is difficult to digest and can give you the feeling of a full stomach during a game. Lasagna, pasta and rice combined with lean beef or chicken are examples of food that can be included in your pregame meal. You should not eat in the hour preceding the game to avoid an upset stomach. Drink adequate amounts of water during a game to avoid dehydration. For every hour of playing time, a kid should drink 20 to 40 oz. of fluids.
STRETCH
Do not overlook pregame stretching and warm-ups. These activities are essential in preventing injuries. Stretching and warm-ups increase your heart's preparedness for the game as well increasing the flexibility of your body. The majority of your stretches should focus on your lower body. Examples of stretches that kids can perform before a soccer game are seated splits, lunges, hamstring stretches, spine twists and calf stretches.
