Peculiarities of correlations between spirometric and anthropometric indicators in practically healthy young women of mesomorphic somatotype

Abstract

The issue of studying the relationships between indicators of the external structure ofthe body and spirographic parameters in persons of a certain sex, age, ethno-territorialzoning remains relevant, especially from the point of view of the need to determine thereference values of indicators of external breathing. The purpose of the study was todetermine the peculiarities of the relationship between spirographic parameters andindicators of the external structure of the body in practically healthy young women of themesomorphic constitutional type of the Podilia region of Ukraine. We conducted acomplex clinical and laboratory study of young women aged 16 to 20 years, whichcorresponds to the youthful period of ontogenesis. 109 practically healthy young womenwere selected, in whom no deviations in the state of health were detected according tothe results of radiography, echocardiography, tetrapolar rheovasography andrheoencephalography, sonographic examination of parenchymal organs of the abdominalcavity and thyroid gland, general and biochemical blood analysis. For this group of subjects, we performed a spirographic examination using the Medgraphics Pulmonary Function System 1070 series according to the methodology of the American Pulmonology Association and the European Respiratory Society (2019). The anthropometric studywas carried out according to the method of V. V. Bunak (1941), the somatotypologicalstudy - according to the calculated modification of the Heath-Carter method (1990).The assessment of the component composition of body weight was carried out accordingto Matiegka method (1921). After somatotyping, it was found that 32 young women hada mesomorphic type of constitution, for which Spearman's correlation analysis wasconducted in the licensed software package "Statistica 5.5". It was established that themajority of spirographic indicators in practically healthy young women of the mesomorphicsomatotype had isolated statistically significant correlations with anthropo-somatotypological parameters, with the exception of parameters that reflect lungcapacities. Vital capacity at rest, had the largest number and strength of correlations, was significantly associated with the value of 24 anthropo-somatotypological indicators. Total, longitudinal and girth body dimensions, the ectomorphic component of the somatotype, muscle, bone and fat mass of the body were most often correlated with thecapacity indicators of external respiration. All speed spirographic indicators and maximum peak expiratory flow were correlated with the skinfold thickness. The study of correlations is the basis of further mathematical modeling to determine the appropriatespirographic indicators in an individual representative of the female sex of the juvenileage of the mesomorphic somatotype.
