Assessment of students' body response to physical exertions based on quantitative criteria of resistance.

Objective: Aim: To investigate the biomechanical indicators of the statokinesiogram to assess coordination-related stability (balance) criteria in students before and after physical exertion.

Patients and methods: Materials and Methods: The research, which was conducted in 2024-2025, involved 30 male students of the 1st-2nd academic years of the main medical group. Methods: analysis and generalization of literary sources, method of computerized stabilography (statokinesiometry), methods of mathematical statistics. The complicated Romberg stance assessed students' balance.

Results: Results: The biomechanical indicators of the statokinesiogram were investigated to assess the criteria of students' stability before and after physical exertion during physical education training sessions. Students demonstrate stable statokinesiogram indicators with a significantly unchanged ellipse area of the COM oscillations before and after exertion (SEllS - 3606 and 4004 mm2; α > 5 %). The leading role of proprioceptive, amplitude-frequency characteristics of the body's COM oscillations in balance control has been proven.

Conclusion: Conclusions: It has been established that maintaining balance by a student is a dynamic phenomenon that requires continuous body movement, which is the result of the interaction of vestibular and visual analyzers, joint and muscle proprioception, central and peripheral nervous systems. The cause of body mass center fluctuations is respiratory movements, blood circulation, as well as the functional state of the central nervous system and receptor apparatus. The effectiveness of the stabilography method for assessing the coordination criteria of stability (balance) of students before and after physical exertion has been proven. The results obtained indicate that physical exercises have a positive effect on improving the indicators of students' stability (balance).
