The study purpose is to determine the age-related peculiarities of motor preparedness of 7th-9th grade girls of a village school. Materials and methods. The study involved 7th grade girls (n=9), 8th grade girls (n=9), 9th grade girls (n=12). The children and their parents were fully informed about all the features of the study and gave their consent to participate in the experiment. The following research methods were used to solve the tasks set: analysis of scientific and methodological literature, pedagogical testing and methods of mathematical statistics for processing research results. Results. The 7th-9th grade girls show statistically significant changes in the results of the following tests: test 1 “Shuttle run 4×9 m” (t=5.108, P=0.001); test 3 “Arms’ bending and straightening in a hanging position” (t=-3.448, P=0.003); test 4 “Bent-arm hang” (t=2.216, P=0.047); test 5 “Long jump” (t=-2.161, P=0.044); test 6 “Evaluation of time parameters 5 seconds” (t=-2.639, P=0.016); test 9 “Stange’s test” (t=-4.521, P=0.001); test 10 “Genci’s test” (t=-4.662, P=0.001); test 11 “Serkin’s test 1” (t=-3.616, P=0.002), and test 12 “Serkin’s test 2” (t=-2.400, P=0.027). The 9th grade girls show the best results in tests 1, 2, 5, 6, 9-12. The 7th grade girls show the best results in test 4. Conclusions. The 7th-9th grade girls show a positive dynamics of the functional condition of respiratory and circulatory functions. The level of motor and functional preparedness of the village school 7th-9th graders is assessed as average.
