Inspiratory Muscle Training in Individuals With Cystic Fibrosis

Cystic fibrosis is a genetic disease that affects some organs of the human body. Among them, the lungs tend to be the most affected due to the accumulation of mucus in the airways, which in addition to avoiding the passage of air, favors pulmonary infections. With the evolution of the condition, secondary complications arise, such as postural changes, decreased respiratory muscle strength, decreased functional capacity and, consequently, quality of life. Therefore, respiratory muscle training may be an intervention that improves the respiratory condition of these individuals, allowing an improvement in the quality of life and may delay the evolution of respiratory symptoms. Thus, this study aims to investigate a home protocol of respiratory muscle training on respiratory muscle strength, lung function, quality of life, posture and functional capacity in adolescents and adults with cystic fibrosis. The researchers believe that the training can cause an improvement in the studied variables, and can be inserted in the usual treatment of these patients.

This group will initiate inspiratory muscle training with 40% of the MIP load and each week will have a load increase of 10% of the initial MIP up to 4 weeks of training

Inclusion Criteria: Diagnosis of cystic fibrosis, confirmed by the sweat test; 14 - 25 years; Clinical stability; Absence of bacterial colonization for 4 weeks; Both sexes; Exclusion Criteria: Inability to perform the protocol established by the study; Present any intercurrence during data collection; Being unable to understand and / or perform procedures. Colonization during study participation; Patient hospitalization due to worsening of the clinical picture.
