The article presents the results of a study devoted to the development and experimental testing of a specialized methodology for training goalkeepers in mini-football in the U-18 and U-21 age groups. The specifics of the game activity, technical and tactical requirements for the goalkeeper's game, as well as current trends in the development of mini-football as a sport with increased dynamics and intensity were taken into account. The main goal of the study is to develop an experimental methodology for training goalkeepers (age groups U-18, 21) in mini-football, taking into account the specifics of the game activity, technical and tactical requirements, and modern trends in the development of game sports. Research methods: analysis and generalization of scientific, methodological and special literature, analysis of practical experience of coaches and sports schools, system-structural analysis of the components of goalkeeper training, observation of the training and competitive process of goalkeepers, pedagogical testing of goalkeeper qualities, questionnaires and interviews of coaches and players to assess the current requirements for a modern goalkeeper, pedagogical experiment, methods of mathematical statistics (averages, variance, coefficient of variation, etc.; assessment of the reliability of changes (Student's t- test; determination of the dynamics of the increase in indicators between the stages of the experiment), video analysis of goalkeepers' game actions (quantitative and qualitative analysis of situations in matches), biomechanical analysis of movements. In the process of research and analytical work, the need to revise traditional approaches to goalkeeper training, which are adapted mainly from big-league football and do not fully correspond to the realities of mini-football, was substantiated. The proposed experimental methodology is based on the principles of individualization, systematicity and variability of the training process. It includes means of developing special coordination, speed and strength qualities, tactical and game thinking and stress resistance. The results of the pedagogical experiment demonstrated the effectiveness of the implemented methodology: athletes from the experimental groups recorded a statistically significant increase in the level of technical and functional preparedness compared to the control groups. The development has practical value for coaches, methodologists and teachers involved in the training of young goalkeepers in specialized youth sports schools, academies and amateur clubs. Prospects for further research in the chosen direction of scientific exploration include improving methodological approaches using digital technologies (video analysis, tracking, load sensors, VR simulators) to increase the accuracy of assessing the technical and tactical actions of goalkeepers.
