The article presents a methodology for the comprehensive diagnosis of sports abilities (motor 
qualities and competitive motor reaction) in children aged 7-9 years under the conditions of school 
physical education lessons. The study was conducted during the 2024-2025 academic year at two 
general education schools in the city of Aktau and involved 272 boys from grades 1-3. The 
methodology consists of two stages: I stage of standardized tests of general physical fitness (30 m sprint, 
3х10 m shuttle run, 6-minute run, standing long jump, sit-and-reach test, pull-ups); II stage applied 
motor tasks based on national games («Botany tartyp alu», «Qarsylasqa janasu») aimed at assessing 
reaction speed, coordination, and strength manifestations in conditions of motor confrontation. The 
obtained data ware systematized by age and grade groups. A positive progression of key physical 
qualities from grade l to grade 3 was identified, and the selective potential of the game-based trials was 
demonstrated through a reduction in the proportion of finalists at successive stages. The proposed 
scheme is focused on standardizing assessment procedures, optimizing lesson time, and enabling the use 
of diagnostic results for pedagogical load planning and initial sports orientation of schoolchildren.
