We all want to be in the best physical condition possible. Teens involved in sports are no exception. Sports are competitive, whether the competition is between people who want to win or within a person who wants to continually improve performance. In either case, using food or nutrients to more quickly reach a goal of improved performance is compelling. While adults can probably recognize safe or unsafe nutritional practices, teens wanting to reach a goal in sports will rarely consider potential risks.
To improve exercise performance, the production of energy, or ergogenesis, must be enhanced. Ergogenic aids are practices intended to improve performance. Since the beginning of time, people have used nutritional ergogenic aids ranging from eating muscle meat to taking mineral pills. Some of these aids are useful, some have nothing more than psychological effects and some can be risky.
Water is, by far, the most important aid to performance although it does not itself produce energy. Dehydration is one of the greatest threats to health especially when superimposed on performance demands. Performance is not harmed by drinking water unnecessarily. Drinking a glass of water before, during and after sporting events is the best advice for all athletes and exercisers.
A clearly useful performance booster is carbohydrate, especially complex carbohydrates or starches. The body depends on carbohydrate as its major supplier of energy which means that to have a little extra, particularly for long-term exercise, can guard against early fatigue. There is a safe way to build a little extra store of carbohydrate. About a week before an endurance sporting event, eat half the calories as starchy foods while training heavily for three or four days. Then switch to a light training or resting period and eat 75 percent of the calories from carbohydrate. This should allow a doubling of carbohydrate storage. Regular sports drinks or fruit juices during long-term exercise will not only replace lost energy supplies but also replace fluid and electrolyte losses.
Protein needs are greater for the exercising adolescent. Usually, their typical food intake is sufficient to meet their needs. Protein drinks or amino acid supplements are only useful if the teen does not eat meat or other complete protein sources. Likewise, there are no ergogenic benefits to supplements of vitamins or minerals unless the nutrients are deficient.
From ancient Greeks to modern athletes, ergogenic practices have been touted and abandoned. With all this experience it is clear that the Food Guide Pyramid gives us the best, and easiest to follow, advice for sports nutrition. Add plenty of fluids and enjoy all the fun building a healthy body through sports can offer.
