Development of a basal metabolic rate prediction equation for elite sambo and judo wrestlers: a pilot study
https://doi.org/10.33667/2078-5631-2026-9-57-61
Abstract
Measuring or predicting basal metabolic rate is a first and important step in determining energy expenditure among athletes.
Objective. The aim of this study was to develop an equation for predicting basal metabolic rate for qualified male athletes practicing sambo and/or judo.
Methods. The study involved 25 qualified athletes specializing in sambo and/or judo. Bioelectrical impedance analysis, indirect calorimetry, and mathematical statistics were used.
Results. The developed equation demonstrated high predictive accuracy: the calculated BMR (2249±296 kcal/day) did not statistically differ from the measured one (2249±346 kcal/day) at p=0.997. The model is characterized by a strong correlation (r=0.86), the absence of systematic error (bias 0.12 kcal/day) and confirmed stability in cross-validation (R2=0.796).
Conclusions. The results indicate that the developed equation is a reliable tool for estimating BMR in athletes practicing sambo and/or judo. The model can be used in the practical work of coaches and sports nutrition specialists to more accurately plan energy supply and monitor body weight in conditions where direct measurement methods are unavailable.
