This study focuses on examining the dynamics of strength development in middle school-aged children from 13-14 to 14-15 years old. Control exercises used in the study included torso lifting and lowering for girls and push-ups from a plank position for boys. The research was conducted during the 2022-2023 academic year among 8th-grade students (7 girls and 8 boys) at Secondary School No. 5 in Bukhara. Results were recorded in September and April and analyzed using statistical methods. The findings revealed that both girls and boys showed positive dynamics in strength ability over the school year. In girls, the average score in the torso lift and lower test increased from 45 to 48, while in boys, the push-up test scores improved from 31 to 36. The study demonstrates that the rapid development of the muscular system and the proper organization of physical exercises positively influence the growth of strength ability in children of this age.
