Relationship between body weight and indicators of physical and emotional status in 12-13-year-old girls

Abstract

This article is focused on assessing the influence of body weight on the indicators of physical and emotional status of 12-13-year-old girls. The aim of the study was to examine the relationship between body weight and indicators of physical and emotional status in 12-13-year-old girls. The study involved 108 girls aged 12 and 30 girls aged 13. The following methods were used: analysis of scientific and methodological literature, anthropometric, pedagogical, physiological methods, and methods of mathematical statistics. Results. The study revealed statistically significant (p < 0.05) correlations between body mass index (BMI) and indicators of physical development, functional status, physical fitness, physical activity, and value orientations of 12-13-year-old girls, as well as factors negatively influencing their attitude towards physical education classes. The study also identified a direct statistically significant relationship between BMI and the value orientations in the subjects. An increase in BMI was associated with the reinforcement of terminal values such as independence and love, as well as instrumental values like cheerfulness. The research revealed that normal body weight has a positive impact on the development of physical abilities of 12-13-year-old girls, specifically agility and trunk flexor muscular strength and endurance. According to the obtained data, the number of correlations between BMI and other studied indicators of physical and emotional status, physical activity, and value orientations increased with age. While 12- year-old girls had 12 such correlations, 13-year-old girls had 15. Conclusions: The abovementioned necessitates the consideration of these findings in the justification and development of exercise programs based on the use of health fitness means for girls with insufficient body weight.
