Flexibility is an essential quality for an athlete, which is why a high level of flexibility is required to increase efficiency and economy of movement, which interests all sports disciplines.The purpose of this scientific approach is to show that the development of static flexibility specific to foot techniques in karate, for practitioners between the ages of 14 and 18, is not done at random. The drive systems, applied within the programme proposed in this study for the development of flexibility, are subject to anatomically determined laws of motion, are functional and succeed in a methodical sequence.The experiment performed on karate practitioners - Shotokan emphasizes the importance of developing specific mobility which will allow them to execute foot techniques at a higher level and achieve outstanding performance.The application of the tests and the implementation of carefully selected drive systems that contribute to the development of mobility specific to karate techniques substantiates the working hypothesis and validates through its results the correctness of the experimental operation.
