Crossfit as a means of optimizing the nutritional status of students

Statement of the problem. The problem of selection of effective systems of physical training of students is constantly in the focus of attention of teachers. Currently, there is a sufficient number of studies related to the effectiveness of using various systems of physical exercises in the educational process through bioimpedance analysis, however, a comparative study of the effect of CrossFit and aerobics on the component composition of the body has not been conducted. The purpose of the study is to determine changes in the body composition of students depending on the influence of CrossFit and classical aerobics on it through bioimpedance analysis. The research methodology included the use of scientific literature analysis, bioimpedance analysis method, pedagogical experiment, and methods of mathematical statistics. Research results. The results of the study show a significant increase in muscle mass gain and a significant decrease in the percentage of body fat in сrossfit athletes. In classical aerobics, the fat component significantly decreased, while the increase in muscle mass turned out to be unreliable.
