Background: Correction of the training system in various sports based on the previous competition results analysis is a common practice allowing to quickly increase the training level. However, such studies have not been conducted in MMA for athletes who primarily use a wrestling or striking style of fighting. The purpose of the study was the development and practical implementation of an integral methodology for improving the pre-competition training of athletes, taking into account their fighting style, based on the analysis of the previous competitions results. Material and methods: 10 athletes of the Ukrainian national MMA junior team (16-17 years old) took part in the study. At the first stage of the study, the training process of the pre-competition mesocycle and the 2022 European MMA Championship results were analyzed. At the second stage, the methodology for correcting the training process was developed and implemented during 2 months of pre-competition preparation for the 2022 MMA World Championship. At the third stage, there was a comparative analysis of the athletes’ performance results in both competitions. Results: The study showed that using the "classical" method of pre-competition preparation for the European Championship contributed to the fact that during the competition, 68.7% of the fights were won. The use of the experimental methodology for two months of training contributed to the development of maximal strength by 8.8% in athletes with wrestling style and by 20.6% in athletes with striking style of fighting. The practical implementation of increasing the adaptive body reserves during pre-competition training was carried out during the World Championship. 84.4% of the total number of fights were won. At the same time, the number of fights, which ended early by knockout, painful or choke hold, or with a clear advantage, increased by 19.0% compared to the results of the European Championship. Conclusions: The use of the integral training method allowed increasing the implementation of technical skills and functional capabilities of athletes, taking into account their style of fighting in competitive activities.
