<p><strong>The purpose of the work</strong><strong>: </strong>to determine the impact of Kyokushinkai Karate classes on the ability to adapt to different physical activities of boys of 10-12 years of age during classes.</p><p><strong>Material and methods</strong><strong>. </strong>78 boys of 10-12 years were surveyed, 27 of them expressed their desire to participate in the sports section of Kyokushinkai Karate (EG). CG (29) includes guys who do not have contraindications for playing sports. The essence of the forming experiment was to compare the growth rates of individual indicators of physical qualities, functional preparedness of children who attended the Kyokushinkai Karate training program (experimental group - EG) with children who were engaged in physical education only during physical culture lessons (control group - CG). During the year a monitoring examination of children is carried out to assess physical development, adaptation to exercise, adaptive potential of the circulatory system, the functional state of the apparatus of external respiration, the energy potential of the organism, physical fitness and methods of mathematical statistics.</p><p><strong>Results</strong><strong>. </strong>The plan of preparation of training groups on the basis of rational sequence of use of a set and volume of means and methods of physical education of normative part of the сurriculum "Kyokushinkai Karate" is presented. Adaptation processes occurring in the body of boys, during the acquisition of knowledge and skills within the walls of the school are determined by a number of educational, behavioral, everyday and other factors, each of which has a specific purposefulness to achieve a useful end result of learning. The course of study at school is undoubtedly accompanied by the adaptation of children to the new mode of study, rest, psychological and physical activity, and the question of the dynamics of indicators of functional systems of the child's organism came to the plane of our research.</p><p><strong>Conclusion. </strong>In the course of the research, we came to the conclusion that the plan developed and implemented in the sports circles improves the adaptation capabilities of the boys of this age group during Kyokoshinkai karate classes.</p>

<em>Objective</em>: substantiation of the expediency of using mathematical evaluation criteria for determining the means of diagnosing a set of knowledge, skills and other competences acquired during the training of military men in the emotional (affective) sphere. <em>Material: </em>the study was attended by 67 cadets of the Air Force University, who are not the pilots and are at the 3rd year of study. For assessing the ability to manage their behavior through management of emotions, a technique of studying the emotional intelligence of military personnel at different stages of training and physical tests are  related to overcoming objective and subjective obstacles. For the processing of the results was used the method of correlation, discriminant analysis and decision tree methods for the classification problem. The significance level for all statistics was established at p &lt;0.05. <em>Results: </em>A positive linear relationship between the levels of performance of special exercises and the level of emotional stability were established. The models of discriminant analysis and the rule of classification of the recognition of the level of emotional stability according special physical preparedness level are determined. It was established that exercises in the obstacles course and turns in the gymnastics wheel are the main variables that allow classifying the students according to the level of emotional stability. <em>Conclusions: </em>The using of mathematical criteria for evaluating the results of the implementation of special exercises can differentiate according to the objective characteristics of cadets in category and simplifies the methodological work on recognition in the dynamics of physical improvement of military personnel, a local assessment of emotional and volitional resistance to the negative impact of the factors of modern combat.
