Structure of the technical and tactical training methodology for ice hockey goaltenders aged 15-17 based on action variability under conditions of uncertainty

The purpose of the study is the theoretical justification and structuring of the methodology for technical and tactical training of ice hockey goaltenders aged 15-17, based on the principle of controlled variability of actions under conditions of game uncertainty, aimed at increasing the reliability of competitive performance. Research methods and organization. The research is of a theoretical and design nature. The main methods used were theoretical analysis of scientific and methodological literature on the issues of goaltenders training and the formation of motor actions under conditions of uncertainty, as well as pedagogical modeling. Research results and conclusions. A structural model of technical and tactical training has been developed, which includes four interconnected blocks: enhancing the stability of performing basic technical actions under standard conditions, managing the variability of actions when changing one situational parameter, creating conditions of uncertainty when changing two or more situational parameters, and simulating game situations with limited time for decision-making. It is substantiated that the variability of actions should be considered as a controlled pedagogical parameter that ensures the formation of an adaptive and stable system of game actions. The implementation of the principle of controlled variability creates prerequisites for improving the reliability of competitive activity of goaltenders aged 15-17 under conditions of uncertainty.
