Annotation:

The purpose of the research is to study the influence of actual nutrition on the nutritional status of athletes of both sexes professionally engaged in rowing.

Research methods and organization. During the training camp, 36 athletes (20.5 ± 1.2 years old) of the Russian national team engaged in rowing were examined. The actual nutrition, anthropometric parameters of nutritional status and daily energy consumption were studied by the frequency method with the help of heart rate monitoring.

Research results and discussion. In the examined group of athletes, sexual dimorphism is expressed: in women, engaged in rowing, lean body mass is 30% lower, active cell mass is 34% lower, skeletal muscle mass is 33% lower than in male rowers. The analysis of the results of actual nutrition revealed that the energy value of the rations averaged 3197 ± 1173 kcal / day. The contribution of proteins to the average energy value of the diet was sufficient (16.8%), the contribution of fats (43.3%) exceeded the recommended level, and the contribution of carbohydrates (39.9%) was low. In men, the average energy content of the diet and the consumption of macronutrients were significantly higher than in women. The basal metabolism in men averaged 1982 ± 165 kcal / day, which is 27% higher than in women (1560 ± 130 kcal / day, p = 0.0001). The daily energy consumption in male rowers (6173 ± 1551 kcal / day) was 1.5 times higher than in women (p = 0.0001). When comparing the daily energy consumption, obtained by heart rate monitoring, and the energy value of the actual nutrition, obtained by the frequency method, an energy deficit was found in athletes of both sexes. At the same time, it was 1.4 times higher in men than in women.

Conclusion. In order to increase the speed-power parameters and cardio-respiratory endurance, recommendations are given, both for the individual correction of the diet and the range of dishes in the canteen menu. It is advisable to develop a combined methodology for studying the actual nutrition of athletes using electronic devices, aimed at improving the accuracy of the results.
