Abstract
Objective: to study the objective and subjective parameters of the functional “cost” of technical and tactical activities (TRIMP, standard units, RPE, score) and compare them with the expert assessment of technical and tactical readiness of young professional football players (EXPERT, score). Materials and methods: 30 students of the professional football academy (mean age 16.4±1.2 years) were tested with Polar Team Pro sports technology from Polar (Finland). The professional football coaches (n=6, license A-C) after each official game scored (from 1-10).an expert assessment of the implementation of the players technical and tactical readiness. Results: a linear relationship between the physiological indicator “training impulse” (TRIMP) and the expert assessment of coaches of technical and tactical readiness were found. Were revealed that RPE subjective information from athletes-players is a convenient express method of receiving feedback, but it does not demonstrate a high correlation with technical and tactical readiness. The variance analysis found a decrease in functional costs in official matches relative to training sessions. Conclusion: the combined monitoring of subjective (RPE) and objective (TRIMP) parameters of functional “cost” is the most effective in practice.
