Methodological aspects of studying the actual nutrition of athletes

Abstract

Analysis of actual nutrition of athletes and its correspondence to energy expenditure seems relevant as a balanced diet produces a direct effect on physical endurance and professional performance of athletes. It is meaningful to estimate not just nutritional and energy value of the diet, but also a degree of diversity of basic groups of food products as sources of essential nutritional substances in the diet of athletes along with dietary fibers to optimize the gut microbiome diversity. Regular studies of actual nutrition conducted with certain time intervals and simultaneous assessment of biomarkers characterizing the alimentary status enable to trace their effect on professional performance, effectiveness of the training process, adequate restoration and health for every athlete and the whole team.
