Objective. The purpose of this study is to highlight some of the methods for the correct development of body mobility for karate training in order to achieve sports performance. Methods. Since the concept of mobility is not applied methodically in karate, and the stretching principles are practically unknown, I have presented in this paper a compendium of exercises that contribute to the development of mobility and a karate- shotokan application program, starting from methodical and anatomical principles on the basis of basic training in athletics and gymnastics. The research was carried out in two stages: the first stage was to determine the individual level of body mobility of the subjects and the second stage to be carried out for eight months and to evaluate the final progress achieved after observing the training method I proposed to develop the mobility of karate- shotokan practitioners. Results. In order to ascertain whether the progress made by the experimental group is significant, trustworthy and that they are not due to chance, but to our intended action, we calculated the statistical index "t" (STUDENT test). The differences in the value of the results obtained between the averages of the two tests Ti (initial test) and Tf (final test) are significant, certainly 95%. Cowclusiows. Considering the fact that after the final testing a good homogeneity of the team can be ascertained as well as an important increase of the statistical indices, we can conclude that the actuation systems applied in the experiment were well selected. It is very important to ensure through a logical and well-thought-out training the development of all the elements that contribute to the sporting form of a karate- ka including mobility.
