Goal . Study of the energy exchange of young athletes during a one-year training cycle. Methods. The survey involved 52 cyclical sports athletes aged 14-19 years, qualification - I-II category, at the stage of intensive sports disciplines. Results. When comparing the dynamics of basal metabolism with the performed training load during a weekly cycle of athletic training discovered a certain relationship, the change in the volume and intensity of training load has caused relevant changes of basal metabolic rate. The obtained values of these indicators indicate the maximum intensity of the energy supply systems of the body and are criteria for the maximum activity of energy processes. The total value of the total energy consumption per day for representatives of various sports was approximately the same and amounted, respectively: 3477±219 kcal for athletes, 3566±477 kcal for swimmers, and 3626±464 kcal for rowers. Conclusion. Energy expenditure in the conditions of the main exchange was, as a rule, lower than the proper values on average by 2-8%. However, the statistical difference in all cases is unreliable (p>0,05). The energy supply of training loads used in sports practice in young athletes corresponds to an average level of 47-68% of the maximum aerobic capacity. The share of energy expenditure during sports training is 27-38% of the total daily value. ; The Conference is organized by the Faculty of Physical Medicine and Rehabilitation of the Georgian State Teaching University of Physical Education and Sport
