171 The article highlights the static-dynamic nature of balance during turns, the role of micro- and macro-oscillations of the body, as well as the importance of sensory integration under conditions of limited visual control. The influence of the initial (signal) position and the spatiotemporal organization of movement on the reliability of performing rotational elements of varying complexity is emphasized. It is concluded that a comprehensive biomechanical approach combining the analysis of kinematic parameters and postural stabilization mechanisms makes it possible to deepen the understanding of the factors of turn stability in rhythmic gymnastics. The obtained generalizations create a scientific basis for improving the methodology of specialized training of gymnasts and enhancing the technical reliability of performing rotational elements. Keywords: rhythmic gymnastics, rotational elements, biomechanical analysis, kinematic parameters, postural control, turn stability, static-dynamic balance, neuromuscular coordination. Rhythmic gymnastics belongs to sports characterized by high demands on movement coordination, precision of spatial orientation, and the ability to maintain postural balance under conditions of minimal support [9]. A special place in the structure of competitive programs is occupied by rotational elements, the performance of which requires a combination of high angular velocity, precise control of the position of body segments, and stability of the supporting segment [11]. The success of a turn in rhythmic gymnastics is largely determined by the effectiveness of postural control, which is developed through many years of specialized training. Postural control in rhythmic gymnastics is purposefully developed from an early age, since sports training usually begins before the age of six and is characterized by a significant volume of daily training loads [7]. Already at the initial stages of training, athletes master exercises that require maintaining a vertical body position under single-support conditions-both on the full foot and on the toes in the relevé
