This is an excerpt from the paper...
The purpose of this study was to examine the oral-nasal breathing of a sample of 12 subjects (6 females and 6 males) running a treadmill at 3.4 miles per hour with a 1% increase per minute. Prior research had shown: (1) a good deal of variance in the amount of time it takes subjects to switch from complete nasal breathing to at least some oral breathing; and (2) a breathing pattern wherein, typically, subjects begin by inhalation and exhalation solely through their noses, move into a phase where they inhale through their nose and exhale through their mouth, and finally as they tire, inhale and exhale through their mouth. This study attempted to see if the just delineated pattern was repeated for sample subjects as well as whether the point where subjects shifted to at least some oral breathing significantly differed as a function of differences in subjects' age, gender, or physical condition. Subjects' switching points were not found to significantly differ as a function of the age, gender, or physical condition variables. However, the typical oral-nasal breathing pattern observed in prior studies was again observed in this study. When do people running on a treadmill switch from nasal to oral breathing; and is this switching point significantly different depending upon differences in people's gender, physical condition or age? Determining the answer to these questions was the research problem undertaken in this study.

itude of between subject variance in oral-nasal breathing has also been observed in other studies, and has been found to be so great that in some cases subjects never switch to oral breathing while in other cases, some subjects rely entirely on mouth inhalation and exhalation. It seems reasonable to suggest that there may be factors which contribute to variance in oral-nasal breathing during exercise. This study specifically examined for the possible effects of three subject-related factors of age, gender and physical condition.
Finally, one finding of most of the cited studies has been that for those who do make the shift from nasal to oral breathing, this is done in a fairly predictable pattern consisting of a first phase wherein subjects both inhale and exhale through their nose. During the second phase, there is a tendency for subjects to inhale through their nose but exhale through their mouth while in the third and final stage, subjects both inhale and exhale through their mouths. This study also examined for whether this pattern was evidenced by sample subjects.
