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.
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.
本研究旨在评估成年农村人口的呼吸系统功能，并估计呼吸系统功能参数与身体活动水平及身体成分之间的相关性。该研究涉及一组116名年龄在35 - 60岁的农村人口，他们参加了为期3周的康复营。他们被分为两组：男性（29人）和女性（87人）。分析了身体特征：身高、体重、体重指数（BMI）和身体成分，检查了吸烟状况和申报的身体活动（PA）水平。为评估呼吸系统的功能参数，采用了流量 - 容积曲线模式。测定了以下参数：肺活量（VC）、用力肺活量（FVC）、一秒用力呼气容积（FEV1）、呼气峰值流量（PEF）、MEF50（肺活量50%时的最大呼气流量）和蒂芬诺指数。测量了握力以及膝关节屈伸肌的最大扭矩。正如预期的那样，男性的呼吸参数水平明显更高。在分析吸烟状况时，可以说大多数受试者是吸烟者。
呼吸系统功能参数的值与他们的年龄相符，在正常范围内，未显示出肺通气障碍。该研究的大多数受试者申报的身体活动水平较低，这可能是由于在农场从事体力劳动所致。吸烟仅在男性组中显著降低了FEV1、PEF和MEF50等参数的值，但这些值并未表明通气障碍。呼吸系统参数与肌肉力量参数的相关性最高。也注意到与身体成分参数（去脂体重、水分）有显著相关性。
