The relationship between the indicators of morpho-functional state, physical development, physical fitness and health level of girls aged 12-13 years

Abstract

The article presents the results of the pedagogical experiment that lasted during 2017-2018 academic year. Altogether 205 girls of 12-13 years of age were involved in the research. To achieve this goal, an integrated approach was used with the application of the following research methods: analysis and synthesis of references; anthropometric methods; determination of the level of physical health; pedagogical testing; physiological methods; methods of mathematical statistics. The coefficient of canonical correlation between the indicators of physical health, on the one hand, and physical fitness, on the other, in the schoolgirls with a low level of physical health is r = 0.569; in the girls with the level of physical health below the average r = – 0.735 and in the girls with the average level of physical health r = –0.791. It means that each higher level of physical health of the subjects is determined by a higher-quality state of their physical fitness. We found out that of 105 possible comparisons between the individual components of physical health and physical fitness of the 12-13year-old girls, 67 (or 64 %) positive cases of medium and high dependence were recorded. The results of our research prove that the main components of physical fitness in terms of the impact on the physical health of the girls aged 12-13 years are indicators of aerobic endurance r = 0.440-0.743, of speed-strength qualities r = 0.355-0.692, of strength and strength endurance r = 0.322 - 0.735. Their priority is due to the most significant correlation coefficients with four of the five components of physical health surveyed.
