Effects of cold air inhalation combined with prolonged submaximal exercise on airway function in healthy young males

Abstract

In a group of 30 well trained young males (age 10-36 years) we did not find clear changes in spirometric values during and after 20 minutes submaximal exercise and cold air inhalation down to -16 degrees C. Smaller cold-related changes in lung volumes, breathing pattern and specific airway conductance was found, however. The youngest age group was not particularly cold-sensitive concerning airway function. Two subjects showed considerable stronger airway reaction than the rest of the group.
