Abstract

Introduction Breathing mechanic is determined by tonus and flexibility, correct contraction amplitude of the thoracic diaphragm, relaxation, and the activity of auxiliary muscles. Respiratory muscle strength is evaluated by measuring the static maximal inspiratory (MIP) and expiratory (MEP) pressures. The aim of this research was to determine the relationship between MIP and MEP and body posture in female soccer players. Material and methods The research involved a group of 57 women aged 16-20 years (42 soccer players and 15 controls) without disorders in the movement apparatus, cardiovascular system, or respiratory system. MIP and MEP were measured and analyzed with respect to body posture in three different positions. MIP and MEP values were evaluated with Micro Respiratory Muscle Analyzer (CareFusion). The body posture in the coronal plane from the back measured with a non-contact 3D photogrammetry system. Results Asymmetries in body posture were also measured and compared between groups. Asymmetry was observed at all anatomical locations in each of the postural positions, with an increase in asymmetry of the scapulae in the soccer players (p = 0.008). The control group had increased asymmetry at the skull nuchal line. Conclusions These results draw attention to the need for standardizing the evaluation procedure for respiratory muscle strength and interpretation of results. Postural measurements allow linkage of specific postural errors to the maximum strength of inspiratory and expiratory muscles. The asymmetrical location of the scapulae may be followed by a disturbance in the maximum strength of the inspiratory muscles.
