Discriminant Analysis: Age-Specific Features of Motor Fitness of Girls Aged 7 to 9

Abstract

The purpose of the study was to determine the age-specific features of the motor fitness of girls aged 7 to 9. Materials and methods. The study participants were 27 girls aged 7, 40 girls aged 8, and 35 girls aged 9. The children and their parents were informed about all the features of the study and gave their consent to participate in the experiment. The study used such research methods as analysis of scientific and methodical literature, pedagogical observations, motor fitness testing, a probabilistic approach to the assessment of the learning process, and methods of mathematical statistics. Results. The level of proficiency in gymnastic exercises, the level of development of coordination abilities, endurance and speed strength are those indicators that can be used to assess the motor fitness of girls aged 7 to 9. Attention is drawn to the fact that the level of proficiency in exercises is a key element in the motor fitness of girls. The obtained discriminant functions have statistical significance both in the classification of data and in the determination of the structural features of the motor fitness of girls aged 7 to 9. Conclusions. The standardized and structure coefficients of the discriminant function indicate that the most important indicators in the motor fitness of girls aged 7 to 9 are the level of general endurance, coordination of movements, relative arm strength and the level of proficiency in gymnastic exercises.
