Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treadmill exercise, speed and incline set to achieve an exercise intensity of 60% of each subject's peak VO2 for 20 minutes on one occasion. Peak VO2 measured on the day prior to randomisation.
Positive expiratory pressure (PEP). Subjects breath through a PEP device which provides an expiratory pressure at the mouth of 15-20cmH2O. Subjects breath through this device for 15 breaths, followed by the Forced Expiratory Techinique. This cycle is repeated six times in a 20 minute period on one occasion.
Control (resting breathing). Sitting quietly, relaxed breathing for 20 minutes on one occasion.
