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.

“…The results of the study coincide with the results of Ivashchenko, Iermakov and Khudolii (2021), Kruglov and Khudolii (2022), Khudolii, Golovnin and Bartík (2020) on age and gender peculiarities of development of certain physical abilities in primary school children and their structure.…”

Features of the development of coordination abilities in young schoolchildren

“…These data and other studies [9,10,11,12] confirm the importance of early intervention and the development of targeted programs aimed at improving coordination abilities and physical activity among younger schoolchildren to maintain their health and well-being in the long term. Furthermore, these and other studies emphasize the importance of an individual approach and the adaptation of physical exercises to the age and gender characteristics of children.…”

Control and Evaluation of the Strength Abilities of Primary School-Aged Karate Boys

“…From a health perspective, this decline is a cause for concern, as many studies have shown an inverse correlation between muscle fitness and obesity, cardiovascular disease, and metabolic risk factors in youth (Piek, Bayman & Barnett, 2016;Biernat, Krzepota & Sadowska, 2018;Gjonbalaj et al, 2022). The authors' opinions coincide with the need to develop a comprehensive series of tests that are easy to use to assess motor skills (Masanovic, Gardasevic, Marques et al, 2020;Marchenko & Verdysh, 2021;Kruglov & Khudolii, 2022). This will definitely strengthen the data on longitudinal trends in the physical fitness of children and adolescents around the world.…”
