Clinical Trial Summary

The purpose of this study is to compare physiological responses in cardiovascular variables between nose and mouth breathing at rest and during exercise.

Description:

Breathing patterns can affect the cardiovascular system. Little is known about how nose versus mouth breathing affects cardiovascular variables (blood pressure, heart rate, etc.) at rest and during exercise. It has been suggested that breathing through the nose can cause calmness and lower blood pressure. However, research is needed to examine the extent to which breathing through the nose affects cardiovascular variables at rest and during exercise. Therefore, we will compare cardiovascular variables between nose-only and mouth-only breathing. The rate of breathing will be fixed (using an audible metronome) for both breathing conditions (nose-only vs mouth-only) based on an individual's free breathing (i.e., no breathing cues) breathing rate.

Related Conditions & MeSH terms

• Healthy
• Mouth Breathing

Intervention

Behavioral:
• Nose-only breathing
Participants will breathe only through their nose (mouth closed) during rest and submaximal exercise.
• Mouth-only breathing
Participants will breathe only through their mouth (nose clips prevent nose breathing) during rest and submaximal exercise.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Blood pressure during exercise between study arms	Systolic and diastolic blood pressure will be measured in the laboratory at rest and during submaximal exercise with nose-only breathing and mouth-only breathing.	Up to one day
Primary	Heart rate during exercise between study arms	Heart rate will be measured in the laboratory at rest and during submaximal exercise with nose-only breathing and mouth-only breathing.	Up to one day
Secondary	Rating of perceived exertion during exercise between study arms	Participants will report their rating of perceived exertion (numerical scores of 6-20, with 20 being the greatest exertion) based on a validated scale at rest and during submaximal exercise with nose-only breathing and mouth-only breathing.	Up to one day
Secondary	Rating of perceived breathlessness during exercise between study arms	Participants will report their rating of perceived breathlessness (numerical scores of 0-10, with 10 being the greatest breathlessness) based on a validated scale at rest and during submaximal exercise with nose-only breathing and mouth-only breathing.	Up to one day
