Comparative Overview of Motor and Functional Preparedness of 7th–9th Grade Boys of Rural Underfilled School

Abstract

The study purpose is to determine the age-related peculiarities of motor and functional preparedness of boys studying at a rural underfilled school. Materials and methods. The study participants were boys of 7thgrade (n = 8), 8thgrade (n = 7), and 9thgrade (n = 6). To achieve the purpose set, the study used the following research methods: analysis of scientific and methodological literature, pedagogical testing, and methods of mathematical statistics for processing research results. The test program consisted of the well-known tests: “Shuttlerun4×9 m”,“Arms’ bending and straightening in a lying position”, “Arms’ bending and straightening in a hanging position”, “Bent-arm hang”, “Standing long jump”, “Evaluation of movement time parameters(running time 5, 10 and 15 seconds)”.“Stange’stest”, “Genci’stest”,and“Serkin’stest”were used toevaluate the functional state. Results. The analysis of motor preparedness of the 7th-9thgrade boys of a rural school showed that the 7th-graders are less physically fit compared to the 8th- and 9th-graders. The 8th-9thgrade boys show the best results in almost all the tests. There are statistically significant differences between the boys in tests characterizing strength preparedness. According to the results of functional preparedness, the 7th-9thgrade boys show high results in “Stange’stest” and“Serkin’stest”1 and 3.The 8thand 9thgrade boys have the same functional states of respiratory and circulatory functions. Conclusions.The boys show a high dynamics of functional state of respiratory and circulatory functions, as well as of strength preparedness. The 8thand 9thgrade boys statistically significantly differ in the indicators of motor coordination and speed strength. By the results of other tests, the difference in preparedness is not statistically significant. Regression equations (unstandardized canonical discriminant function coefficients) allow to calculate schoolboys’ level of preparedness. A comparison of the obtained result with centroid values makes it possible to divide schoolboys into groups by their level of preparedness. A classification of boys by the level of motor preparedness is possible based on relative strength, motor control ability, and general coordination tests.
