Summary

Dysfunctional breathing and persistent hypocapnia can be associated with many of the symptoms experienced by patients such as dyspnea, fatigue, chest pain and palpitations. The identification of dysfunctional breathing and hypocapnia in these patients is important as it may represent a target for treatment.

In many of these patients, tachypnea at low levels of exertion suggests increased respiratory muscle activity, which can lead to the sensation of dyspnea. Sympathetic hyperactivity leads to excessive and irregular ventilation during exercise. In this way, inspiratory muscle training can improve symptoms (dysfunctional breathing), possibly by attenuating the metaboreflex (vagal modulation-attenuation of the sympathetic response) of the inspiratory muscle in post-covid-19 subjects, reducing ventilatory variability.

DEVICE

Experimental Group

After the initial assessment, all volunteers will receive a POWERbreathe® classic light resistance device (POWERbreathe®, Nsc, Brazil), to carry out the training, and will be individually guided on how to use it and how to complete the protocol. They will perform a trial session to familiarize themselves with the device that will not be considered for analysis. Every week, volunteers will receive a telephone call from researcher 2, who will not participate in the evaluation, to confirm whether the exercise with the POWERbreathe® will be performed appropriately at the recommended frequency, intensity, and duration and whether there are any questions regarding the protocol. At the end of each week, participants will receive a video call from researcher 2 to adjust the device according to G1's weekly load progression.
