Background: Using different models of strength training in MMA is one of the components of improving the training of athletes of different fighting styles. However, there was conducted no study of the impact of different training loads, structure of workouts on the level of training of striking style athletes during selection fights. The aim of the study was to improve the correction system of special kick training and to study its effectiveness during selection fights by modeling training loads. Material and methods: 60 athletes aged 16±0.9 years using a striking fighting style took part in the study. At the first stage, the results of selection fights for the 2021 Ukrainian Championship were analyzed in terms of using different kicks. At the second stage, the development of correction models for special kick training for each group took place. During next 3 months, the proposed training models for participation in selection competitions for the 2021Ukrainian MMA Cup were applied. At the third stage, there was a comparative analysis of the ratio of using 8 different kicks by the study participants during both selection competitions. Results: Using the developed training models had a different effect on the ratio of kicks performed by the participants of all groups. The 1^st and 2^nd group athletes demonstrated the unchanging priority of using “left/right kick” at all stages of the study. Despite the significant difference in the structure of models, a comparative analysis of two selection fights showed increased usage of this kick (18.2%). The ratio changes of other 7 kicks in athletes of groups 1 and 2 depended on the features of training load and energy supply modes. In the 3^rd group athletes who used the training model developed on the principle of premature fatigue, the priority of kicks changed during the study. At the beginning, 15.2% of the total number of kicks during fights were “side kick to the head”. However, at the end of the study, the priority of this kick decreased by 3.0%. The leader among athletes of the 3^rd group (16.4%) was the “direct back leg kick from one-sided fighting stance”. Conclusions: Improving the correction system of special kick training due to the development of new models of strength training allows to increase the athletes’ level of training during the selection fights.
