The study used the following methods: analysis and collation of scientific and methodological literature, general scientific methods of theoretical level, such as analogy, analysis, synthesis, abstraction, induction, as well as general scientific methods of empirical level: observation, testing, experiment. The testing program included well-known tests.</p> <p><strong>Results.</strong> In identifying the state of motor abilities development in boys aged 12-14, the most important results were obtained in tests: 10 “Squats Test (two legs), quantity of times” (0.519), 9 “Trunk Lift Test, quantity of times” (0.497), 21 “Flamingo Balance Test - single leg balance test” (-0.496), 1 “Pull-Up / Chin Up Test (low crossbar), quantity of times” (0.428), 19 “Hand Tapping Test, sec.” (-0.427), 20 “Seated Forward Bend, cm” (-0.412), 5 “The subject lies in prone position, arms bent at the elbow 90 degrees - hold position in seconds” (0.408). These tests characterize the comprehensive development of motor abilities in boys aged 12-14.<span class="Apple-converted-space"> </span></p> <p>In identifying the state of motor abilities development in boys aged 13-14, the most important results were obtained in tests: 8 “Decline Reverse Crunch on Bench, quantity of times” (-0.989), 11 “Single Leg Squat (SLS) Test - right leg, quantity of times” (0.965), 1 “Pull-Up / Chin Up Test (low crossbar), quantity of times” (0.676), №13 “Single Leg Squat (Pistol) - right leg” (0.682), 17 “Eurofit Sit Up Test (for 30 sec.), quantity of times” (0.454). These tests characterize the development level of<span class="Apple-converted-space">  </span>relative and static leg strength, strength endurance of abdominal muscles, and dynamic strength of shoulder muscles.</p> <p><strong>Conclusions.</strong> A discriminant analysis made it possible to determine informative indicators for comprehensive control of motor abilities development in boys aged 12-14; to answer the question as to how significantly the states of motor abilities development in boys aged 12, 13 and 14 differ; what motor tests most substantially influence the differentiation of classes; what class the object belongs to based on the values of discriminant variables.</p> <p>To identify the level of motor abilities development in boys aged 12-14 years, it is necessary to focus on the indicators of relative strength and strength endurance; in boys aged 13 and 14 years – on the indicators of strength endurance of abdominal muscles and endurance of leg muscles.</p>}, number={3}, journal={Physical Education Theory and Methodology}, author={Khudolii, O.
