The purpose of the study is to identify the characteristics of flexibility manifestation in artistic and rhythmic gymnastics. Research methods: analysis of scientific and methodological literature, comparative analysis, myotonometry, methods of mathematical statistics. Research results and conclusions. A comparative analysis of movement flexibility in artistic and rhythmic gymnasts was conducted based on myotonometry indicators. Significant differences were identified in the amplitude of "tension–relaxation" in most muscle groups. Particular attention was paid to the relationship of these indicators with intermuscular coordination, movement fluidity, and flexibility. The results indicate that the myotonometry method is an objective and informative tool for assessing intermuscular coordination and flexibility in technical and aesthetic sports. It is recommended to include elements of "cross" training in athletes' preparation: for rhythmic gymnasts, exercises to develop explosive strength (similar to those in artistic gymnastics) to improve the precision of movements, and for artistic gymnasts, rhythmic and wave-like exercises to develop the ability for rapid muscle relaxation and enhance the aesthetic component of routines.
