This research is devoted to studying the scientific and methodological foundations for developing special physical qualities in 10–12-year-old judokas. The study examines the dynamics of the development of key physical abilities such as strength, agility, coordination, and flexibility, as well as the scientific justification of the interconnection between physical preparation and judo technique (kuzushi–tsukuri–kake). An experimental 12-week training program involving 28 young judokas was conducted. The results demonstrated a significant improvement in all physical indicators in the experimental group: strength increased by 21.3%, agility by 12.4%, coordination improved by 2.12 seconds, and flexibility increased by 7.2 cm. The findings confirm that an integrative approach — combining physical exercises with technical training —is highly effective for young athletes. The proposed methodology is recommended for use in sports schools, judo sections, and initial training programs. The outcomes of the study contribute to the scientific planning of training processes for young judokas and provide practical guidance for coaches.
