objective. The aim of this study was to evaluate functioning of the respiratory system and to estimate the correlation between the function parameters of the respiratory system and the level of physical activity and body composition in the adult rural population. The study involved a group of 116 people from rural population aged 35–60 years, staying on 3-week rehabilitation camps. They were divided into two groups: men (29) and women (87). The somatic features: body height, body weight, Body Mass Index (BMI) and body copmposition were analysed, on the status of smoking and declared level
of physical activity (PA) was checked. For the evaluation of the functional parameters of the respiratory system the pattern of flow volume curve was used. The following parameters were determined: vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), MEF50 (maximum expiratory flow at 50% of VC) and Tiffenau index. Hand grip and maximum torque of the knee join flexor and extensor muscles was measured. As expected, men had significantly higher levels of respiratory parameters. In analyzing the status of smoking cigarettes, it can be stated that the majority of subjects are smokers.
conclusions. The values of functional parameters of the respiratory system were suitable for the age they were within the norm and did not show lung ventilation disorder. Most subjects of the study declared low physical activity which may be due to manual work on the farm. Smoking cigarettes significantly lowered the value of such parameters as FEV1, PEF and MEF50 only in the male group but the values did not indicate ventilatory disorder. Parameters of the respiratory system show the highest correlations with the parameters of muscle strength. Significant correlations with body compositions parameters (FFM, water) have been noticed too.
