Materials and methods: 67 athletes were examined, including involved in rowing (n=18), ice hockey (n=24) and student basketball players (n=25). The actual nutrition of athletes was studied by the frequency method using the computer program “Analysis of the state of human nutrition.” General deviations from the principles of a balanced diet are typical: excessive fat intake (39-45% of the energy value of the diet at the recommended level of no more than 30%) against the background of low carbohydrate intake (36-39%) and sufficient protein (16-17%). Insufficient consumption of vegetables and fruits, an extremely high content of eggs, sausages and confectionery, a low amount of dairy products, and a low content of fish were revealed. In order to increase the adaptive potential of athletes, it is necessary to introduce into practice educational programs for athletes and representatives of the coaching staff, doctors in sports medicine on the principles of diet formation.
