[Seasonal rhythm of airway resistance and intrathoracic gas volume in healthy females and males (author's transl)].
Airway resistasnce (Rt) and intrathoracic gas volume (IGV) were measured every month for 1 year between August 1978 and July 1979 in 9 female and 9 male volunteers. The outside temperatures on the corresponding dates were also noted . Both ggroups showed in the mean a statistically significant increase of Rt and a light fall of IGV during the winter (January). The specific airway resistance (SRt=Rt X IGV)  showed the same trend of statistically significant higher values of SRt ( p less than 0.005) during the winter. Then declined and reached a plateau which was in both groups slightly above that of the previous summer. The correlation coefficients between outside temperature and airway resistance roup as a whole were statistically significant.
