Comparison of key indicators of external respiration function in students of three health groups

Purpose: to define key indicators of function of external breath of students of three groups of health taking into account various total sizes of a body. Material and Methods. For an assessment of breathing function, volume and highspeed characteristics the diagnosing Eton installations (Russia) and Schiller (Switzerland) were used. Results. Age peculiarities of respiratory ventilation disorders and differentiated assessment of circulatory and metabolic parameters according to the total body size in the special health groups (SHG) are analyzed in the article. Breathing volumetric characteristics were examined among the 17-18 aged students in the different health groups. Special attention is paid to the effect of the long-term severe bronchial patency disorders which lead to the respiratory muscles overstrain and the decrease of their strength endurance. This results in the lungs capacity decrease which is typical for the special health groups'' students. Conclusion. It is shown that the students of the 1st health group had lower body weight and the same body length in comparison with the 2nd and 3rd groups. This determined unequal role of respiration in providing vital processes in terms of educational activities, especially in case of disorders of musculoskeletal and cardio-respiratory systems.
