Yogalates is a modern form of fitness exercise that combines yoga (body style) and Pilates exercises, designed in 1997 by Pilates instructor (Jonathan Orla) who aimed to integrate both sports into a system with its own advantages and benefits. One of the most important benefits of this system is the development of motor abilities, which is one of the elements that influence effectively in all sports, especially in rhythmic gymnastics, as the possession of special motor abilities by female students determines the level of motor performance that requires a high compatibility between skills and music. The importance of research in providing students with motor abilities that qualify them to perform the skills of the compulsory motor Assortment in the rhythmic gymnastics bystanding on the effect of yogalates exercises in raising the level of these abilities that directly affect the performance of the motor Assortment. The aim of the research is to identify the effect of yogalates exercises on some motor abilities and the performance of the compulsory motor Assortment in rhythmic gymnastics for third stage students
