Sports nutrition is an important part of sports science. It is about helping sports people get the right food, the right nutrients. So that their bodies are as prepared for that sport as they can be. To make them as competitive as possible. But it doesn't just help sportspeople. The same principles can be used by people whose purpose is simply exercise. Different sports and activities require different nutrition for example. Different sports involve different amounts of energy consumption. It's important to get this right because if the person doesn't get enough calories in their food, he or she won't have the energy they need to compete at their best. On the other hand, if too many calories are consumed the person may put on weight. Obviously, not what the athlete needs. Sports nutrition isn't just about what happens before competing. Recovery from competition is also very important. For example, foods that are rich in protein can help the muscles repair themselves after strenuous exercise. So, that the sports person is ready for the next event.
