FEATURES OF EXTERNAL RESPIRATION OF ADOLESCENTS OF DIFFERENT MEDICAL GROUPS OF PHYSICAL EDUCATION

Relevance. One of the human systems, which is particularly acutely affected by external environmental factors is the respiratory system. These disorders in adolescence are especially noticeable when intense and dramatic changes in the child's body on the path  to biological maturity occur. Goal. The purpose of our study was to evaluate the functional indexes of the external respiration of adolescents of different medical groups of physical training. Materials and methods. The functionality of the respiratory system was evaluated by the results of pneumothography and respiratory retention. They were evaluated using mathematical statistics using the Medstat program (Yu.E.E., 2006). 76 middle school age pupils (38 boys and 38 girls) were surveyed, which belong to the preparatory group of physical training and 40 peers (20 boys and 20 girls) who attend the main physical education group. For comparison,  normal indexes were used according to computer conclusions and scientific literature data Results. The normal performance of the VC according to the results of computer conclusions, registered in 42 % of pupils of the preparatory group of physical education, higher than the norm have 21 % of adolescents, 36 % of adolescents have significant violations of this index. According to the computer's conclusion, 52% of the subjects are characterized by extremely significant changes of FVC. A similar pattern is also noted for the index in the boys of this group. According to the results of computer findings 69% of pupils of the preparatory group  have normal indexes of PEF, 21% have a higher then norm, 10% a slight decrease. The results of the functional test of Shtanger (delay in inhalation) showed  that in the preparatory group this index is lower than the norm Volumetric indicators of the external respiration of pupils of the preparatory group in more than half of adolescents are significant changes. The volumetric indexes of such adolescents are significantly lower than the norm, by almost 1 liter. The rates of the respiratory system of the MEF 25, 50, 75% are lower than the norm by 1.5 - 2 times, and PEF does not differ from the norm. Conclusions. Indexes of external respiration in more than half of the examined pupils of the preparatory group were changed. The volumetric and flow rates of the respiratory system were significantly lower than the norm. A similar trend was followed by functional respiratory tests.
