The rapid expansion of Brazilian jiu-jitsu (BJJ), against the backdrop of territorially heterogeneous access to highly qualified coaches, makes the task of developing a scientifically verified methodology for autonomous training particularly significant. Within the present study, a comprehensive, validated system of independent training for a BJJ athlete is formed, aimed at the targeted optimization of specific physiological characteristics and the development of key psychological competencies under conditions of limited external supervision. The methodological basis includes a systematic review of academic literature, a comparison of block periodization protocols, and a content analysis of practices for the use of wearable technologies to objectify training load. The obtained results made it possible to construct an integrated model based on the logic of block periodization (accumulation, transmutation, and realization blocks) with an emphasis on the development of strength endurance and power; in particular, in the transmutation block it is advisable to use intensities on the order of 85–90%. It is demonstrated that psychological predictors of sports performance, including Perseverance (r=0.179) and Self-efficacy, are statistically associated with the athlete’s level of experience and require purposeful formation through self-reflection protocols. A self-monitoring system combining field testing (jump tests) and the use of inertial sensors is considered a critically important component for timely load adjustment and reduction of the pronounced risk of injury, estimated at 5.5 injuries per 1000 hours of training. Practical implementation of the proposed methodology provides the athlete with tools sufficient to achieve competitive readiness under conditions of self-training, compensating for the absence of continuous coaching supervision, and the presented materials are of interest to competitive BJJ athletes focused on systematizing the process and maximizing performance.
