Özet
Total lung capacity and its subdivisions, maximum breathing capacity and forced expiratory volume in 1 sec were measured using a 91 spirometer in 200 male and 161 female normal Turkish subjects 21 to 40 years old to establish normal values. The subjects were from different socio-economic communities. Statistical analysis was performed to determine the relationship of the measurements to age and the physical characteristics of the body, and the best regression equations were found for predicting lung volumes and maximum breathing capacity (MBC). Best prediction formulae were, in general, found to be based on body height and age. All volumes and MBC were found to be higher in males, and taller subjects had higher lung volumes and MBC in both sexes. The comparisons were made between present absolute values and the values obtained from literature, and between the correlation coefficients of present data and those of others. Some prediction formulas reported in the literature were also applied to the present data and the difference between the calculated and observed mean values was shown. It was concluded that the data from the present study were in agreement with those of some authors but at variance with others. These discrepancies can be explained by the different age range, different occupations and races and also by the difference in physical fitness of the subjects in the different studies. © 1971 S.
