Background and purpose Regulation of physical activity in the process of training mixed martial arts (MMA) fighters is one of the most important problems, as it affects aspects of the individual approach to the process of training athletes. To control and regulate the level of physical activity when performing a special training program for MMA fighters with different fighting styles, both objective and subjective methods of control and regulation should be used. The purpose of the study: to identify the impact of differentiation and regulation of physical activity according to objective and subjective indicators of MMA fighters with different fighting styles on the competitive effectiveness of athletes. Material and methods 42 athletes participated in the study. Athletes were divided into 3 groups of 14 people in each group according to fighting styles: power, tempo, game style. 2 groups of 21 people in each were formed: experimental and control. The control group trained without taking into account the fighting style. In the experimental group, the nature of the load and exercises were selected in accordance with the fighting style. Determination and regulation of physical activity was carried out according to objective and subjective indicators. As objective indicators, heart rate was used in combination with the coefficient of complexity of techniques. As subjective indicators of the load value, the 10-point Borg scale was used. Results The developed methodology for the training process of MMA athletes, taking into account the fighting styles when selecting loads, has proven its effectiveness. This is evidenced by a significant improvement in the results of competitive activity in the experimental group, while in the control group, the change in this indicator is not significant. Conclusions The introduction of a differentiated training system adapted to the specific fighting style of the athlete has a positive effect on their competitive results. The experimental group of MMA fighters demonstrated a significant increase in the coefficient of competitive efficiency after the intervention. In contrast, no such significant changes were observed in the control group. Based on these findings, the developed training system is recommended for use by fighters of different fighting styles. The self-regulation technique using the Borg scale allows fighters with different fighting styles to consciously manage this process, which ultimately leads to an increase in competitive efficiency.
