Power abilities: recognition of the level of development in girls aged 12-14 years

The purpose of the study is to determine the possibility of recognizing the state of power abilities development in girls aged 12-14 years based on the methodology of multidimensional statistics. Materials. The study involved girls: 12 (n =21), 13 (n = 20), 14 (n = 19) years old. 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. Results. In the recognition of the state of power abilities development in girls aged 12-14 years the most important are the results in tests: Pull-Up / Chin Up Test (Rope Climbing), quantity of times (0.877); Squats Test (two legs), quantity of times (0.723); Single Leg Squat (SLS) Test - left leg, quantity of times (-0.567); Pull-Up / Chin Up Test (low crossbar), quantity of times (-0.467). These tests describe the level of muscle strength development of the shoulder girdle and legs. In the recognition of the state of power abilities development in girls aged 13-14 years the most important are the results in tests: Single Leg Squat (SLS) Test - left leg, quantity of times (-0.825); Single Leg Squat (SLS) Test - right leg, quantity of times (0.735); Single Leg Squat (Pistol) - left leg (0.672); Hand tapping test, sec. (0.682). These tests describe the level of development of relative and static strength of the legs. Conclusions. Discriminant analysis allowed to determine informative indicators for cross-control of the development of power abilities in girls aged 12-14 years; answer the question of how significantly the state of development of power abilities in girls of 12, 13 and 14 years is different; which motor tests most significantly affect the differentiation of classes; which class the object belongs to (based on the values of discriminant variables). In order to recognize the level of development of power abilities in girls aged 12-14 years, it is necessary to be guided by the indicators of relative and static strength and strength endurance; at girls of 13 and 14 years – strength endurance
