The Factor Structure of Coordination Abilities Development in 5th-7th Grade Boys

The objective is to determine the structure of coordination abilities development in 5th-7th grade boys. Materials and methods. The participants in the study were boys of the 5th grade (n=21), 6th grade (n=20), and 7th grade (n=19). The paper used analysis and generalization of the scientific and methodological literature data, general scientific methods of theoretical level, namely: analogy, analysis, synthesis, abstracting, induction, as well as general scientific methods of empirical level: observation, testing, experiment. To evaluate of the motor preparedness, the results of motor tests, height and body weight were recorded. The materials of the study were processed in the statistical analysis program IBM SPSS 20. Factor analysis was carried out using a model of the principal components with the rotation method: Variamax with Kaiser normalization. Results. Analysis of the similarities shows that the most informative in the structure of the 5th grade boys’ motor preparedness are Test 9 “Static Equilibrium Evaluation by E. Ya. Bondarevsky’s Method” (,999), Test 2 “Standing Long Jump (cm)” (,998), Test 10 “Dynamic Equilibrium Evaluation by Bess Method” (,916); for the 6th grade boys such are Test 9 “Static Equilibrium Evaluation by E. Ya. Bondarevsky’s Method” (1.0), Test 2 “Standing Long Jump (cm)” (,999), Test 5 “Sit-Up for 30 sec.” (,968), Test 10 “Dynamic Equilibrium Evaluation by Bess Method” (,918); for the 7th grade boys such are Test 2 “Standing Long Jump (cm)” (,994), Test 9 “Static Equilibrium Evaluation by E. Ya. Bondarevsky’s Method” (,987), Test 10 “Dynamic Equilibrium Evaluation by Bess Method” (,945). Conclusions. The most informative in the structure of 5th-7th grade boys’ coordination abilities is vestibular tolerance. For pedagogical control of 5th-7th grade boys’ motor preparedness the following can be recommended: Test 2 “Standing Long Jump (cm)”, Test 9 “Static Equilibrium Evaluation by E. Ya. Bondarevsky’s Method”, Test 10 “Dynamic Equilibrium Evaluation by Bess Method”.
