The present study aimed to investigate the relationship between postural stability, external breathing, and sex, as this area of research is not yet well explored. The study included 19 healthy participants, both male and female, and compared their breathing parameters in three positions: sitting, standing, and supine. The objective was to collect data to develop a non-contact method for recording external respiration. The analysis included measurements of vital capacity and forced vital capacity pulmonary tests, as well as parameters of natural breathing. We confirmed that the lung volume component was higher in males than in females in the sitting position. Additionally, postural influence on breathing was observed only in male participants, with no significant impact on females. Men also exhibited an increased respiratory rate in both standing and supine positions, as well as increased minute ventilation when standing as compared to sitting. Furthermore, men demonstrated higher maximum inspiratory and expiratory vital capacities in all positions as compared to women. These results have important implications not only for the development of non-contact methods for recording respiration but also in the studies of vertical stance, in clinical investigations.
