Consuming beetroot juice, which contains a lot of nitrate, is a new trend in the world of sports over the past few years. Supplementing with dietary nitrates may improve performance because it enhances muscle efficiency and oxygen supply to the muscles. But it's also a bit controversial because the consumption of nitrate was always associated with possible health risks.
Athletes engaged in heavy training programmes, or in the final preparation for competition, appear more susceptible to infection than the general population. This increased susceptibility to infection arises due to exercise- or training-induced suppression of the immune system. Nutritional practices can help to maintain or improve immune function and limit the risk of illness compromising training and competitive performance.
Compared to most other athletes, competitive swimmers typically have more training sessions per week and often begin swimming at a younger age. A balanced diet is not only essential for optimising performance but also for enhancing recovery between training sessions. For young swimmers, it is equally important to consume adequate energy for growth and development. Therefore, good nutrition should be more than just a sports bar and sports drink during a competition.

When exercise intensity increases, carbohydrates are the main fuel for athletes.
