Parameters of Functional Lateral Organization of Students of Medical University with Different Levels of Physical Fitness

Abstract

INTRODUCTION: One of the parameters of the functional reserves of the human body is the level of physical fitness, which depends not only on the improvement of various methods used in the education of students in physical culture, but also on the individual characteristics of students, including parameters of their functional lateralization.

AIM: To establish the character of the interrelations between the parameters of functional lateralization and the parameters of physical fitness in medical university students.

MATERIALS AND METHODS: Functional lateralization was determined by both the conventional test methods and by the method of neuro-energo mapping in 120 practically healthy medical university students of male gender aged 18 to 23 years. Physical fitness was assessed in conventional tests for determination of strength fitness, speed-strength fitness, speed endurance. All the data were processed using non-parametric statistical methods and correlation and cluster analysis.

RESULTS: Based on the criterion of physical fitness, young men were divided to two groups: a group with a relatively high level of speed and strength endurance and flexibility (cluster 1, n = 71), and a group with a relatively high level of strength fitness (cluster 1, n = 49). Both the integral (coefficient of lateral organization profile C_LOP) and partial parameters (manual and sensory asymmetry) of the functional lateralization were higher in the representatives of cluster 2, with this, the analysis of changes of the permanent potential level (method of neuro-energo mapping) in functional tests showed only an emerging tendency in the differences between the clusters. Also, in cluster 1, weak (r < 0.3, р < 0.05) negative relationships between the parameters of functional lateralization were found in behavioral tests, and between changes in the permanent potential level of the left and right cerebral hemispheres (Td–Ts lead) in load tests. In the representatives of the second cluster, no correlations were found.

CONCLUSION: The results of the performed comprehensive analysis evidence, in the authors’ opinion, the differences in the central-peripheral relationships in the systemic organization of physiological functions that determine non-uniform physical fitness in young men with a relatively high level of speed-strength endurance and flexibility (cluster 1) and those with a relatively high level of strength fitness (cluster 2).
