FACTOR AND CLUSTER ANALYSIS OF MORPHOFUNCTIONAL AND MOTOR DETERMINANTS OF STUDENTS’ PHYSICAL STATUS
Main Article Content
Abstract
Students’ physical status is determined by interactions among morphological, motor, and cardiohemodynamic characteristics; therefore, isolated assessment of individual variables limits the preventive value of screening.
Objective – to identify the factor organization of physical development, cardiovascular functional status, and motor fitness in students and to determine typological profiles relevant to preventive monitoring.
Materials and methods. A cross-sectional assessment of young adult students was performed. The protocol included anthropometry, resting heart rate and blood pressure measurements, handgrip dynamometry, and a set of motor tests. Morphological, strength, and cardiohemodynamic indices were calculated. Descriptive statistics, correlation analysis, factor analysis, and cluster analysis were used.
Results. Most participants had normal body mass, while morphological and functional characteristics showed substantial interindividual variability. Factor analysis identified relatively independent domains of body constitution, motor fitness, and cardiohemodynamic load. Clustering revealed profiles that differed in combinations of body mass, physical fitness, and functional cardiovascular load.
Conclusion. An integrated assessment supports interpretation of students’ physical status as a multicomponent system and increases the diagnostic value of preventive screening for targeted correction of physical activity patterns and cardiovascular risk factors.
