Instrumental control of functional indicators in students with health deviation

Abstract

In modern conditions of conducting physical education classes, the role of tools and methods of monitoring the body’s functional characteristics as markers of student’s health state is increasing. Purpose: to study the longitudinal dynamics of the students, studying at a special medical group body functional state features during three years of study at the university. Materials and methods. 314 students of 1-3 years of study at six universities of Russia, having a disease and studying at a special group for physical education took part in the experiment. To determine the indicators of bio-impedance analysis and heart rate variability, the software and hardware complex «MedicalSoft Sports Testing System» (MS FIT – 01) was used. The heart rate indicators were determined; temporal (SDNN, RMSSD), spectral (TP, LF/HF, SI) parameters of heart rate variability, hemodynamic parameters (stroke volume, cardiac output), bio-impedance analysis (BMI, phase angle, basal metabolic rate). Based on certain indicators, the program calculated an integral indicator of health – wellness score (WS). Results. It was found that the 3rd year students of the special group have a higher level of body functional reserves and physical fitness relative to the groups of students in the 1st and 2nd studying years. This fact is confirmed by the body mass index dynamics, basal metabolism, phase angle, heart rate variability, as well as when calculating the integral score. They have a better BMI ratio, more optimal parameters of pumping heart activity and heart rate variability, a physiological level of stress index, higher physical performance in terms of phase angle during university studies. Conclusions. Physical education teachers should pay increased attention to junior students due to their low functional indicators. Timely monitoring of functional indicators should be carried out in order to take measures for prevention, preservation and promotion of health.
