Introduction. During the training process, it is important to monitor the dynamics of body composition indicators. Each of them plays an important role in the functioning of the body when performing physical exertion, and their correct ratio ensures optimal functioning of the body, which allows you to achieve the greatest athletic results. To characterize the ratio of the body component, a method was developed based on the determination of bioimpedance parameters according to standard tables of centile intervals and their scores.
The purpose of the study is to evaluate the indicators of the body component composition index (BCI) students involved in various sports.
Methods and organization of research. The study was conducted based on the results of preventive examinations at the Health Center of 262 students involved in various sports. The examinations included questionnaires and bioimpedance measurements. The calculation of IQT was carried out according to the formula IQT=(kJMT+kAKM+kOOB+kOB)/4) and was rated as unsatisfactory, satisfactory, good and excellent index [1].
The results of the study and their discussion. The dynamics of IQT indicators makes it possible to correctly assess the real changes in the body that occur under the influence of physical exertion. AKM% is used as a correlate of motor activity, physical performance and metabolic rate. The highest values of ACM% and specific OOV were determined in young men engaged in powerlifting (57.1±0.52 and 29.3±0.37). The lower values of the GMI% were determined in boys engaged in swimming (19.7± 1.03), and the highest – from the sports section of table tennis (24.6±0.58). An increase in GMI% indirectly indicates a decrease in the activity of lipolysis processes, the total amount of energy in the body and working capacity. The highest indicators of OV%, which mediate the processes of gas exchange, nutrient transfer, metabolic products, etc., were determined in young men engaged in swimming, skiing and basketball, and the lowest – from the sections of table tennis (55.2±0.43) and volleyball (54.5±0.72).
Girls engaged in fitness have the best indicators of ACM% (53.1±0.28), LMI% (24.6±0.53), OV% (55.3±0.44) and specific OV (27.0±0.37), to a greater extent, girls from the table tennis and volleyball sections have indicators deviating from the standards.
The majority of good and excellent IQT scores were found in boys from the sports sections of swimming (80.0%), athletics (77.8%) and girls engaged in fitness (89.3%) and athletics (70.5%). The impact of game sports on IQT is less significant compared to powerlifting, athletics, skiing, swimming and fitness.
Conclusion. The ICST assessment showed that sports and fitness activities contribute to its improvement to varying degrees (depending on the type of sport).  Monitoring of IQT, as an indicator of the quality of life of a modern person, where sports style has become one of the leading components of lifestyle, allows you to track changes occurring in the body during training, adjust the orientation and volume of physical activity.
