Objective of the study was to scientifically substantiate the use of exogenous and endogenous factors to improve the efficiency of controlling the motor actions of young judokas.
Methods and structure of the study. The research was conducted at the Igor Makarov Judo School in Gomel. Young judokas aged 11-13 took part in the pedagogical experiment, which lasted eight weeks. In the experimental group (n=14), additional exogenous and endogenous loads were used as confounding factors during classes. The control group (n=15) trained according to a program developed for the Youth Sports School of this age range. Monitoring the level of agility of young athletes included tests that included a combination of movements encountered in the training and competitive activities of judokas in familiar and unfamiliar conditions.
Results and conclusions. It was found that the use of disturbing factors in the process of training young judokas aged 11-13 is an effective means of increasing the specific load on the body of those involved, promotes the involvement of reserve capabilities and psychophysiological functions in motor activity. Analysis of the obtained results revealed an improvement in the experimental group's ability to measure the time for completing a certain task and reduce time losses in unusual conditions, optimize the athletes' capabilities for prompt correction of the motor program and spatio-temporal anticipation when changing the environment.

Keywords: young judokas, confusing factors, motor actions, agility, testing, familiar and unfamiliar conditions.
