Feel Breathe, Restriction Device Ventilatory Nasal

Summary

It has patented a restriction and filtering device ventilatory nasal flow FeelBreathe with the aim of increase nasal airflow resistance, therefore the objective was to examine the effects of FeelBreathe with lung ventilation and gas exchange during exercise.

Conditions

• Mouth Breathing
• Restrictive Breathing Pattern

DEVICE

Feel Breathe, restriction device ventilatory nasal

The Feel Breathe (FB) consisted of a small adhesive strip that is placed across the bridge of the nose during exercise. The FB was place following procedures for placement as indicated by the manufacturer's directions, while the placebo nasal, was placed over the nostrils of the subject, without interfering nasal breathing; thus, nasal airflow resistance was not increase. Each subject was required to perform three identical submaximal exercises with intensity at 50% VT1-VT2 under different breathing conditions. The breathing conditions were: oronasal, nasal and FB breathing. All participants performed three trials of stable load (50% VT1-VT2) for 10 minutes in the three conditions mentioned above, setting the cadence at 70-75 rpm, and controlling the same in all three exercise conditions.
