Aim. The aim of this study was to determine gender differences in the level of development and proficiency in coordination motor abilities (CMAs) in athletes of selected combat sports. Materials and Methods. We analyzed the results of our experimental studies and the data and analyses of the material collected by other authors on the differences in the level of development and proficiency in CMAs in female and male wrestlers, taekwondo athletes, and kickboxers. Results. It was found that with age, training experience, and increasing competencies, gender differences in the level of most CMAs tend to decrease. Each athlete has their individual dynamics of development and proficiency in CMAs, which is not consistent for each ability and does not always coincide with the general trend of changes with age. Conclusions. The conclusion from the findings of the author’s empirical research is that the level of various CMAs can be improved across different age categories including preschool children, schoolchildren, and qualified athletes aged 15-29 years. With proper coordination training, younger and middle school children can reach, and often exceed, the CMAs levels of adolescents (boys and girls) at secondary school age. The rates of improvement of various CMAs over the same period in children of the experimental groups and in young competitive athletes may be 10-20% higher than in children or athletes of control groups of similar age. A comparison of the different CMAs in young athletes aged from 11 to 15 years, in whom these abilities have been developed in a systematic manner for one to four years with peers not involved in regular sports training showed that trained boys and girls outperformed untrained individuals by 10-20, 20-40, and even 60-100 and more percent. The analysis of the collected material shows that the assumption that, with equal trainability of girls and boys of preschool age, younger and older schoolchildren, and young and competitive wrestlers, higher responsiveness to identical coordination training programs, however, is observed in girls and adolescent and adult competitive athletes compared to their male peers.
