Nutrition and Athletic Performance

Whether you are a first-time participant at the community sport level or a national team athlete, proper nutrition is essential to overall good health and optimal athletic performance. Participants of all ages and at all levels of competition are affected by good nutrition.
The rules of good nutrition are quite simple. Consume adequate food and fluid before, during, and after training or competition to help maintain blood glucose levels during performance, maximize performance, and improve recovery time. Athletes should be well hydrated before training or competition and they should also drink enough fluid during and after to balance fluid losses.
