Background. Stance (or posture) is the fundamental posture of a hockey player, allowing him to perform various movements during training and playing processes. However, studies of postural balance of hockey players are scarce. Objective. Ye main aim of the study was to test methods of tracking a hockey player’s posture using the DTrack2 and SteamVR Tracking 2.0 systems, as well as to compare static postural characteristics of professional hockey players and beginners, based on the analysis of changes in knee and hip joint angles and head position, during a Zve-minute stance-keeping task. Results. Analysis of movements with the DTrack2 system and the SteamVR Tracking 2.0 system showed identical results, allowing further use of the SteamVR Tracking 2.0 system. Analysis of the positional tracking data showed that professional hockey players were characterized by a greater amplitude of oscillation (1–2 degrees) than novices (no more than 1 degree) when maintaining their stance. Professional hockey players are also characterized by a signiZcantly smaller amplitude of oscillation of the head position during performance of tasks. Qualitative analysis of changes in angles of knee and hip joints showed that professional hockey players, in contrast to beginners, have a higher and more stable amplitude of movement parameters [uctuations during the whole study, which in turn allows to optimize energy expenditure and provide better posture stabilization. Conclusions. Yus, the results of the study indicate the importance of correct head positioning in stabilizing the postural balance of a hockey player. For posture maintenance, the hip strategy of postural balance maintenance, associated with a greater amplitude of hip joint oscillation, is the most optimal.
