Summary

In several diseases in which muscle weakness is a determining factor for morbidity and mortality, inspiratory muscle training has been shown to be useful in improving the function of ventilatory muscles, delaying or minimizing the development of complications due to the reduction of inspiratory muscle strength.

The breath-stacking technique emerges as an easily applicable alternative, and it can be used in poorly collaborative patients. The technique described in the literature aims to increase pulmonary volumes.

This gain occurs with the coupling of a silicone mask on the patient's face, a unidirectional valve and with the expiratory branch occluded. Thus, inspirations occur sequentially in this medium, generating pulmonary hyperinflation and increasing the contractility power of the expiratory muscles, which are fundamental for coughing. This hyperinflation also improves the peripheral air distribution in the lungs by increasing intrathoracic pressure.

The objective of this study is to evaluate the effect of the breath-stacking (BS) technique on the ventilatory muscle strength of young and healthy individuals.

Conditions

  • Muscle Weakness

Interventions

OTHER

Breath-Stacking

Participants will be seated, with their elbows resting on the table, holding the face mask attached to a T-tube and a one-way valve. They will be instructed to inspire and force the expiration inside the mask. The training will be conducted three times a week for a period of four weeks, totaling twelve sessions. The breath-stacking application protocol will consist of three three-minute series, with a three-minute recovery interval between each series, obtaining a total time of fifteen minutes in each session.
