ASSESSMENT OF THE RELATIONSHIP BETWEEN MORPHOFUNCTIONAL INDICATORS AND PHYSICAL FITNESS OF GENERAL SECONDARY SCHOOL STUDENTS BASED ON CANONICAL CORRELATION ANALYSIS

The article examines the multivariate relationship between morphofunctional indicators and the level of physical fitness of 12–13-year-old school students using canonical correlation analysis. It was found that morphological growth indicators, particularly body length and the proportion of muscle tissue, are closely associated with speed-strength qualities. At the same time, an increase in subcutaneous fat percentage was noted to have a negative effect on movement performance. The obtained results demonstrate that the method of canonical analysis enables a comprehensive and scientifically grounded assessment of physical fitness, and the scientific-theoretical as well as practical aspects of this approach are analyzed.
