The BCAAs (i.e., isoleucine, leucine, and valine) appear to exhibit individual and collective abilities to stimulate protein translation. However, the extent to which these changes are aligned with changes in MPS remains to be fully explored.
EAAs appear to be uniquely responsible for increasing MPS with doses ranging from 6 to 15 g all exerting stimulatory effects. In addition, doses of approximately one to three g of leucine per meal appear to be needed to stimulate protein translation machinery.

In addition, food intolerance is on the rise among athletes, but the use of unverified food intolerance tests calls into question an accurate assessment of the state of true intolerance in the population . While physical activity is good for people’s health, intense training, as in the case of elite athletes, harms the immune system and increases the permeability of the gastrointestinal tract. Some studies have linked food intolerance in elite athletes to excessive physical activity . Therefore, in the research , an experimental longitudinal study lasting three months was conducted to assess the impact of food intolerance on sports performance and the health of elite athletes. According to the results of a food intolerance test, an individual elimination diet was drawn up. The blood test showed a decrease in the level of food intolerance after the diet in each athlete, which indicated that the elimination diet significantly improved the athlete’s well-being, making it possible to achieve a faster decrease in heart rate after cardiopulmonary testing.
In addition, the elimination of gluten from the diet means that many carbohydrate foods consumed by endurance athletes are also eliminated from the diet . Iron deficiency anemia occurs in 70% of people with CD . Therefore, it is necessary for such athletes to carefully plan their nutritional needs for training and competition . In cases where CD is accompanied by iron-deficiency anemia, it is vital to follow an iron-rich GFD. A study analyzed nutritional intake during training and competition in the 384 km K4 cycling race of an aspiring long-distance cyclist diagnosed with CD. During the competition, the athlete reported nausea when they tried to consume sugary drinks or marmalade, so their desire to eat decreased. This was probably due to a combination of prolonged consumption of sugary foods and fatigue. Furthermore, the use of dry and crumbly forms of GF foods also proved to be problematic, as some of the food was lost, and the consumption of dry foods can increase the urge to drink. In addition, GF foods tend to be high in calories, which can slow stomach emptying and cause discomfort during exercise . GF foods are energetically rich, but low protein content makes athletes feel hungry despite meals. As a result, against the background of hunger, the development of psychological disorders is possible. The athlete completed his main task to finish the race, but the total race time was almost 2 h slower than expected. This could have been due to insufficient energy intake, which led to the early onset of fatigue. Therefore, for athletes with CD during training and competition, it is necessary to consider alternative dietary regimens to increase endurance .
