Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Group 1: Treadmill exercise, speed and incline set to achieve an exercise intensity of 60% of each subject's peak oxygen uptake (VO2) for 20 minutes on one occasion. Peak VO2 measured on the day prior to randomisation.
Group 2: Chest physiotherapy. Subjects breath out through a Flutter device which provides an oscillating expiratory pressure at the mouth of 10-20cmH2O. Subjects breath out through this device for two minutes, followed by the Forced Expiratory Techinique. This cycle is repeated six times in a 20 minute period on one occasion.
Group 3: Control (resting breathing). Sitting quietly, relaxed breathing for 20 minutes on one occasion.
There is a minimum of 24 hours "wash out" between interventions. All three interventions to be completed within two weeks
