Objectives: To examine the differences in the values of lung volumes and capacities in healthy young subjects of both sexes and the influence of certain parameters (lung diseases, sports) on changes in lung parameters. Study design: A cross-sectional survey Material and Methods: 33 healthy young subjects of both sexes (20 women and 13 men), aged 20-24, participated in the research. All respondents filled out a survey with their personal data (age, gender, body height and weight, and place of residence), questions about their health status (obstructive lung diseases, childhood bronchitis, COVID-19, presence of high blood pressure, cholesterol and blood glucose levels) and lifestyle habits (physical activity, enough sleep, taking nutritional supplements). Their lung volumes and capacities were then measured using the spirometry method using the BIOPAC MP36 device (BIOPAC, Goleta, CA, USA), and the results were analyzed using the Biopac Student Lab 4.1 program. The results of the survey were then compared with the values obtained on the spirometer for both sexes. Results: The male population has a significantly higher level of inspiratory and expiratory reserve volume, and a statistically significantly higher level of all measured lung capacities than the female population. Female subjects who recovered from COVID-19 have a significantly lower level of inspiratory reserve volume, inspiratory, vital and total lung capacity compared to male subjects who had contact with the corona virus. Recreational and active sports significantly affect the differences in the volume of measurable lung parameters. Physical activity has a more significant impact on changes in lung volumes and capacities in men population. Conclusion: Healthy young men have significantly higher values of measurable lung volumes and capacities than women, and sports activity contributes to an additional increase in these values. The impact of COVID-19 infection has a more significant effect on pulmonary parameters in the female population.
