DAILY ENERGY CONSUMPTION OF BASKETBALL ATHLETES DEPENDING ON THE GAME ROLE

The purpose of the research: to study daily energy consumption, metabolism at rest and specific energy consumption of athletes specializing in basketball and to conduct a comparative analysis of the studied indicators depending on the game role.

Methods and organization of the research. The study involved 25 athletes, members of the youth basketball team of the Moscow State Academy of Physical Culture. The average age of the athletes was 20.3+1.7 years (from 18 to 23 years). The energy consumption indicators were determined by indirect calorimetry using an Oxycon Mobil ergospirometer (Jaegr, Germany). Heart rate monitoring was carried out using a Polar M200 wrist-based heart rate monitor (Finland). According to the linear regression equation, the calibration dependence of heart rate and personal daily energy consumption was obtained by the least squares method. A nonparametric analysis was performed using the Kruskal-Wallis test (H-test). The sample was described by calculating the median (Me) and interquantile range in the form of the 25th and 75th percentiles (Q1;Q3).

Research results and their discussion. The daily energy consumption in the groups averaged  3873±690 kcal/day for defenders, 4237±750 kcal/day for forwards and 4854±830 kcal/day for centers. Centers' energy consumption indicators were 25.3% and 14.5%, respectively, higher than those of defenders and forwards (p <0.05). 

Conclusion. The analysis of specific energy consumption revealed a tendency to increase indicators in the “forwards” group. This is probably due to the more active position of forwards on the playing field.
