Effect of exercise on nasal mucous velocity and nasal airflow resistance in normal subjects.
Nasal mucous velocity and nasal airflow resistance were measured in nine healthy subjects before, during 5 min, and 1 h after submaximal exercise of 20 min with a cycle ergometer set in such a way that heart rate ranged from 125 to 135 beats/min. Nasal mucous velocity rose from a base line of 7.6-12.7 mm/min during exercise and returned to the base-line value 5 and 60 min after exercise. The mean expiratory nasal airflow resistance at a flow of 0.4 l/s decreased from a base line of 1.6-0.6 cmH2O . (l/s)-1 during exercise and returned to the baseline value 5 and 60 min after exercise.
