Summary

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

Detailed 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.

Conditions

• Healthy

Interventions

Type	Name	Description
BEHAVIORAL	Nose-only breathing	Participants will breathe only through their nose (mouth closed) during rest and submaximal exercise.
BEHAVIORAL	Mouth-only breathing	Participants will breathe only through their mouth (nose clips prevent nose breathing) during rest and submaximal exercise.
