176 The stability of performing rotational elements in rhythmic gymnastics should also be considered in the context of the static-dynamic organization of movement, where position maintenance is combined with continuous regulation of body posture under the influence of angular loads. Under such conditions, balance is not a purely static state but is formed as a dynamic process that requires constant interaction between sensory, neuromuscular, and mechanical components of movement. It is this interaction that determines the athlete’s ability to maintain the stability of the axis of rotation throughout the entire turn [8]. An important characteristic of postural regulation is the presence of small oscillatory body movements that perform a compensatory function and ensure stabilization of posture under conditions of limited support. Such micro-oscillations allow the balance system to respond promptly to minor disturbances without engaging gross corrective movements. If their effectiveness is insufficient, macro- oscillations arise, manifesting as noticeable deviations of the trunk and disturbances of vertical orientation, which is critical for the quality of turn performance. In rhythmic gymnastics, micro- and macro-oscillations acquire particular significance during the performance of turns in the relevé position, when the support area is minimal and any lateral deviation may lead to a displacement of the axis of rotation. Under such conditions, the effectiveness of postural control is determined by the athlete’s ability to limit the amplitude of macro-oscillations and to maintain movement regulation primarily through subtle corrective mechanisms. A key role in ensuring this stability is played by the so-called signal or supporting posture that precedes the execution of a rotational element. It is the initial body position that creates the prerequisites for the effective realization of the movement phases, determining the spatial location of the center of mass, the nature of interaction with the support, and the possibilities for stabilization during rotation. Errors at this stage tend to accumulate and manifest themselves as disturbances of stability in the main phase of the turn [1]. During rotation, the coordination between the displacement of the body’s center of mass and the dynamics of the center of pressure on the support becomes
