Effect of physical exercise on nasal resistance in normal subjects and in patients with vasomotor rhinopathy

The study has evaluated the behaviour of the nasal resistances, studied using Anterior Active Rhinomanometry, after physical exercise, in normal subjects and in allergic and non allergic vasomotor rhinopathics. The results, in accordance with the literature, show a reduction of nasal resistances in all subjects, particularly in the rhinopathics, immediately after the effort and a return to the starting values after a rest period of 30 minutes. Among vasomotor patients, only the non-allergic group has shown very significant variations in the resistances, because in these subjects there is almost always an exaltation of the neurovegetative system, which we did not observe in the allergic subjects in the intercritical phase. The effort test is therefore, among the aspecific tests of nasal reactivity useful, perhaps, more to therapy than to diagnostic aims.
