Nutrition for Young Athletes


Nutrition for Young Athletes: Fueling Up Before the Game

Nutrition can play a pivotal role in supporting the training and competition demands of any elite athlete.

Food alone will not make you pass the ball faster or knock seconds off your personal best, but the right diet is absolutely central in supporting training to make those achievements possible. Good food choices help ensure fuel needs are met to promote adaptations to training, to aid recovery in order to continue and intensify training and to ensure good health to prevent illness and injury. What you consume before, during and after a game is important for comfort and performance during the game. While eating soon before a game doesn't provide the bulk of the fuel needed for the activity, it can prevent the distracting symptoms of hunger during it. The major source of fuel for active muscles is carbohydrate which gets stored in the muscles as glycogen in the days before the game. This is one reason that the post-game meal is critical to recovery and being ready for the next game.

What Not to Eat

A good diet sometimes starts with not consuming things that you shouldn't. The two biggies for young people are fast food and soda. You can't perform at your peak when you're eating food that is over-processed and made for mass production. Sodas are some of the biggest performance inhibitors out there. The high level of sugar and carbonation forces your body to work harder, and takes energy from you, rather than providing the energy you need to perform. If you simply cut out these two items, you'd be a lot better off nutritionally. You also want to avoid as much processed or packaged food as you can. Examples of this are pre-packaged, or microwave dinners. The more processed the food, the less real nutritional value it has. Any foods with a lot of fat can be very difficult and slow to digest and remain in the stomach a long time. They also will pull blood into the stomach to aid in digestion, which can cause cramping and discomfort. Meats, doughnuts, fries, crisps, and sweets should be avoided in a pre-exercise meal.

Drink Lots of Fluids

You've probably heard this over and over, but you really cannot get enough water and electrolytes. Most young people don't stay hydrated. When you're training intensely, your body depends on good hydration to successfully perform and recover. Find a good electrolyte replacement drink to help with this recovery. Keep a water bottle with you during the day, so you're keeping yourself hydrated all day. If you wait until you're thirsty, it's too late!

When to Eat

Exercising on a full stomach is not ideal. Food that remains in your stomach during an event may cause stomach upset, nausea, and cramping. To make sure you have enough energy, yet reduce stomach discomfort, you should allow a meal to fully digest before the start of the event. This generally takes 1 to 4 hours, depending upon what and how much you've eaten. Everyone is a bit different, and you should experiment prior to training sessions to determine what works best for you.

If you have an early morning game or training session, it's best to get up early enough to eat your pre-exercise meal. If not, you should try to eat or drink something easily digestible about 20 to 30 minutes before the event. The closer you are to the time of your event, the less you should eat. You can have a liquid meal closer to your event than a solid meal because your stomach digests liquids faster.

What to Eat

Because glucose is the preferred energy source for most exercise, a pre-exercise meal should include foods that are high in carbohydrates and easy to digest. This include: foods such as rice or whole wheat pasta, fruits, Choice energy bars and drinks. I use a combination of B vitamins and Vitamin C for my energy drink, works a lot better than the commercial brands with no added chemicals or sweeteners.  

Planning

Planning is essential if you are competing in an all-day event, such as a tournament. Consider the time of your event, the amount of your meal and the energy required. Also, be aware of the amount of fluid you consume. You should plan ahead and prepare meals and snacks that you have tried before and know will sit well with you. Do not experiment with something new on the event day.

Suggested Pre-Training Foods

Eating before training is something only the footballer can determine based upon experience, but some general guidelines include eating a solid meal 4 hours before exercise, a snack or a high carbohydrate energy drink 2 to 3 hours before exercise, and fluid replacement (sports drink) 1 hour before exercise.

1 hour or less before competition

• Fruit or vegetable juice such as orange, tomato, or V-8, and/or
• fresh fruit such as apples, watermelon, peaches, grapes, or oranges and/or
• Energy gels
• up to 1 1/2 cups of a sports drink.

2 to 3 hours before competition

• Fresh fruit
• fruit or vegetable juices
• low-fat yogurt
• sports drink

3 to 4 hours before competition

• Fresh fruit
• fruit or vegetable juices
• rice or pasta with tomato sauce
• baked potatoes
• energy bar
• cereal with low-fat milk
• low-fat yogurt
• toast/bread with limited peanut butter, lean meat (chicken or turkey breast), or low-fat cheese
• 30 oz of a sports drink

Sugar and Performance

If you are an endurance athlete, evidence suggests that eating some sugar (like energy bars, some types of fruit, or sports drinks) 35 to 40 minutes before an event may provide energy (glucose) to your exercising muscles when your other energy stores have dropped to low levels

Caffeine and Performance

Caffeine (tea and coffee) acts as a stimulant on the central nervous system. It had been thought to boost endurance by stimulating a greater use of fat for energy, and thereby reserving glycogen in the muscles. Research, however, doesn't support that theory. When caffeine improves endurance, it does so by acting as a stimulant.

Caffeine can have serious side effects for some people. Those who are very sensitive to its effects may experience nausea, muscle tremors, and headaches. Too much caffeine is a diuretic, and can result in dehydration, which decreases performance.

Eating after Exercise

It is also important to consume carbohydrate, such as fruit or juice within 15 minutes post-exercise to help restore glycogen - your muscles' energy store.

Research has shown that eating 100-200 grams of carbohydrate (such as pasta) within two hours of heavy training is essential to building adequate glycogen stores for the next session. Waiting longer than two hours to eat results in 50 percent less glycogen stored in the muscle. The reason for this is that carbohydrate consumption stimulates insulin production, which aids the production of muscle glycogen.

Carbohydrate plus Protein Speeds Recovery

Research shows that combining protein with carbohydrate in the two hours after exercise nearly doubles the insulin response, which results in more stored glycogen. The optimal carbohydrate to protein ratio for this effect is 4:1 (four grams of carbohydrate for every one gram of protein). Eating more protein than that, however, has a negative impact because it slows rehydration and glycogen replenishment.

Protein Needs after Training

Consuming protein has other important uses after exercise. Protein provides the amino acids necessary to rebuild muscle tissue that is damaged during intense, prolonged exercise. It can also increase the absorption of water from the intestines and improve muscle hydration. The amino acids in protein can also stimulate the immune system, making you more resistant to colds and other infections

Carbohydrates: Athletes need at least 50% of their total calories from carbohydrates, the main energy source for physical activity. Carbohydrates fuel the muscles.

Protein: Ten to 15 percent of total calories should come from protein. Athletes need slightly more protein than those who are less active.

Fats: Athletes need 20 to 25 percent of total calories from fat. Fats are important for allowing the body to absorb fat-soluble vitamins. Some types of fat are 'essential' in and of themselves, meaning that the body cannot produce these types of required fatty acids.

Other nutrients: Most athletes eating a balanced, varied diet with proper choices from all the food groups will meet their needs for vitamins and minerals. If your child is not the type to eat what you suggest, you may supplement with a quality supplement (generic brands are the worse).
