Chronic obstructive pulmonary disease (COPD) is a chronic disease related to various systemic manifestations including dyspnea, exercise intolerance and peripheral muscular dysfunction, with a direct impact on functional capacity. Objectives: To describe a whole body vibration exercises (WBVE) protocol to verify the clinical benefits, and the potential of exacerbation of the disease. Methods: Individuals diagnosed with COPD, aged ≥ 40 years, will be randomly distributed into 4 groups: control group (CG) who will not undergo WBVE, with their normal daily routine; group who will be exposed to WBVE in the sitting position in an auxiliary chair once a week (GS1) and twice a week (GS2); and WBVE group twice a week in the standing position with knee flexion (GP2). The protocol will last 6 weeks, each session will have 5 sets of 1 min vibration with 1 min rest, frequency 25 Hz and peak-to-peak displacement 2.5 mm. Muscle strength and function will be assessed through manual dynamometry and surface electromyography and dyspnea using the Modified Borg Scale (MBS) and the Medical Research Council (MRC) Scale. Discussion: WBVE, due to the various effects already described, seem to be a promising exercise modality for individuals with COPD, potentially being used as an instrument for pulmonary rehabilitation. Previous result showed that the WBVE program can improve the physical performance , the neuromuscular function and the quality of life of individuals with COPD, without the exacerbation of the disease. |
