Minimization of vegetative regulation of heart rate charateristics in the evaluation of the functional status of young professional football players

The study involved 60 young professional football players, living in the North-West region. The functional status was monitored from 9:00 to 10:00 a.m. Registration of heart rate characteristics was carried out by the OMEGA-SPORT hardware and software complex of the DYNAMICS Research and Production company (NPF) (Saint Petersburg). Statistical analysis was performed in the application program STATISTICA. 12.0. Multiple linear regression analysis was used to solve these problems. It was found, that three parameters make the greatest contribution to the integral predictor "functional status, %": pNN50%, HF ms, LF ms, amongst wide range of statistical and spectral indicators of heart rate variability. Reducing the number of analyzed characteristics makes it possible to expand the physiological rationale for managing the functional status of young athletes, specializing in football, as well as to optimize the training load in the shortest possible time.
