This article provides a comprehensive analysis of the requirements for rhythmic gymnastics leotards and examines various materials used for their production, with a special focus on the experimental study of the deformation properties of three types of biflex. Their maximum elongation capacity is studied, which is crucial for ensuring the comfort and functionality of sportswear. The testing methodologies used to assess these characteristics are described in detail, and the potential applications of the research findings in the design and production of sportswear are discussed. The conducted research has led to the formulation of recommendations for selecting the most suitable materials for rhythmic gymnastics leotards, considering their functional and aesthetic requirements. Particular attention is given to aspects such as breathability, elasticity, and color fastness of materials, ensuring durability and comfort in use. The research results demonstrate that the correct choice of materials and processing technologies can significantly improve the quality and performance characteristics of sportswear, which is especially important for professional athletes. Thus, the article presents valuable recommendations and conclusions that can be useful for designers and manufacturers of sportswear aiming to create high-quality products that meet modern standards and requirements.
