179 mechanisms. This creates prerequisites for a deeper understanding of the nature of turn stability and opens opportunities for further experimental research in this area. Conclusion. The conducted theoretical and biomechanical analysis allows us to assert that the stability of rotational elements in rhythmic gymnastics is the result of a complex interaction between the kinematic characteristics of movement and mechanisms of postural regulation. In this sport, a turn is not reduced to an isolated rotational movement around the vertical axis but is formed as an integral static- dynamic process, within which balance maintenance is a continuously regulated function. The quality of performing rotational elements directly depends on the athlete’s ability to maintain a stable axis of rotation under conditions of a minimal support area and the action of significant angular loads. The analysis showed that an effective postural control plays a key role in ensuring turn stability; it is formed over many years of specialized training and is manifested in the ability to limit excessive oscillatory body movements. In particular, maintaining an optimal relationship between the position of the center of mass and the dynamics of the center of pressure creates prerequisites for stable movement regulation both in static balances and in dynamic rotational elements. A reduction in the amplitude and velocity of postural oscillations serves as an indicator of rational movement organization and a high level of sensorimotor control. An important factor in rotational stability is also the quality of the initial, or supporting, position, which determines the conditions for the execution of subsequent movement phases. Errors in the spatial organization of the body at the stage of preparation for the turn tend to accumulate and negatively affect stability during rotation. This emphasizes the importance of biomechanically grounded formation of signal postures in the training process and the necessity of their targeted analysis. The obtained generalizations indicate the expediency of considering turn stability not only from the standpoint of movement mechanics but also within the broader context of neuromuscular and sensory regulation. The integration of visual, vestibular, and proprioceptive signals, rhythmic coordination of body segment actions, and individual postural strategies form the functional basis of the technical
