Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Experimental Procedure: The subjects underwent an initial interview in which was filled in a form of anamnesis, in addition to being assessed and reassessed by spirometry, dynamic circumference and manometer. Moreover, responded international physical activity questionnaire (IPAQ - short version) in order to characterize the physical activity level of each participant being classified as inactive, irregularly active, active, and very active. The same examiner performed the assessments and reassessments of individuals after a training program.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Spirometry: It was performed by a portable spirometer Easy One® , according to the guidelines of the American Thoracic Society / European Respiratory Society (ATS / ERS). The values obtained were compared with the values predicted by Knudson et al..

Cirtometry Dynamics: provided information on the degree of thoracoabdominal mobility and was performed with the use of a tape measure , which was used to measure the chest circumference during maximal inspiratory and expiratory phase . Measurements were taken horizontally at three different levels: axillary, xiphoid and abdominal, taking as references the axillary fold bottom edge of the xiphoid and umbilicus, respectively. Three measurements on each level were performed.

The maximum values of inspiration and expiration were obtained, being considered for analysis, the highest value of the three measurements and subsequently the Index of Amplitude (IA) proposed by Jamami et al. was calculated in order to mitigate the different dimensions of the chest and abdomen.

Respiratory muscle strength : They were taken with the subject in a sitting position using a digital manometer (MVD300 - Globalmed®) calibrated, nose clip, with the nozzle held firmly between his lips.

The maximal inspiratory pressure (MIP) was obtained by a maximal inspiration preceded by a maximal expiration next to the residual volume (RV) , and to measure maximal expiratory pressure (MEP) a maximal inspiration was next performed to capacity total lung (CPT) followed by a maximal expiration.

The evaluation was considered complete when the individual performed three acceptable measures and, among these, a minimum of two reproducible . The last value found could not be superior to the others. Maneuvers with the support pressure by three seconds, and reproducible measurements with a variation less than or equal to 10% of the highest value were considered acceptable. For analysis was considered the greatest pressure value achieved. MIP and MEP obtained the values predicted by the equations of Neder et al. were compared.

Cliniflo group (CG)

Training using flow-oriented incentive spirometry Cliniflo

Group Type EXPERIMENTAL

Cliniflo group (CG)

Intervention Type OTHER

CG: slow deep breaths through the mouthpiece of the incentive Cliniflo® from tidal volume (TV) were performed until the total lung capacity (TLC), holding the maximum inspiration. The volume flow of 100 ml / s for Cliniflo® was standardized, being envisaged to keep the yellow indicator behind the "happy face" for all individuals.The training lasted approximately 50 minutes, were held twice a week on alternate days, for five consecutive weeks, totaling 10 sessions. Performed three sets of 15 repetitions.

Voldyne group (VG)

Group Type EXPERIMENTAL

Voldyne group (VG)

Intervention Type OTHER

VG: slow deep breaths through the mouthpiece of the incentive Voldyne5000® were conducted from the tidal volume (TV) until the total lung capacity (TLC), holding the maximum inspiration. All individuals should maintain "yellow cup" ("yellow flow cup") at a range of flow "Best" in as long as possible. The training lasted approximately 50 minutes, were held twice a week on alternate days, for five consecutive weeks, totaling 10 sessions. Performed three sets of 15 repetitions.
