Efeito de um programa de alongamento muscular pelo método de Reeducação Postural Global sobre a força muscular respiratória e a mobilidade toracoabdominal de homens jovens sedentários

Abstract

Respiratory muscle stretching using the GPR method was efficient in promoting an increase in maximal respiratory pressures, thoracic expansion and abdominal mobility, suggesting that it could be used as a physiotherapy resource to develop respiratory muscle strength, thoracic expansion and abdominal mobility.

“…The transverse abdomen increases the intra-abdominal pressure and stabilizes the spine. A satisfactory activation of this muscle by the volunteers may be associated with SP measurements, since they are related to the maintenance of expiratory air column pressure for phonation (4) . As a limitation of the study, the reduced number of subjects is highlighted, and considering that, in the literature studied, no similar studies were found, the discussions and inferences about the findings of this research become restricted.…”

“…The sound pressure (SP), measure that depends on complete glottic adduction and control of laryngeal movements is influenced by the increase in subglotal air pressure and expired airflow, as well as the maximum phonation times (MPT), which are related to support/duration of phonation and evaluate the coordination between levels of vocal production (2) . The muscle recruitment is essential for the maintenance of the respiratory system's mechanics that, under pathophysiological conditions in which muscle strength is altered, leads to a decrease in respiratory pressures, chest movement and subglotal air pressure (3,4,5) . Studies indicate that vocal production deficit may originate from respiratory capacity disorders, since this function is a source of energy for vocalization, especially in the expiratory phase (6,7) .…”

“…Studies indicate that vocal production deficit may originate from respiratory capacity disorders, since this function is a source of energy for vocalization, especially in the expiratory phase (6,7) . The respiratory muscular support and postural adequacy contribute to a more stable voice, with greater projection and control of laryngeal hyperfunction (4) . The respiratory muscles and their insertions should act synergistically and recruitment of the body power center (BPC) may increase the neuromuscular control (8) , strength and resistance of the abdominal support to the voice.…”

Relationship between body balance, lung function, nutritional status and functional capacity in adults with cystic fibrosis

“…In addition, increased lumbar lordosis is often noted in these patients; this change may cause an associated imbalance of the muscular system that will inhibit normal movement. Interestingly, some investigators demonstrated that postural reeducation improves respiratory muscle strength and the ability to expand the rib cage in sedentary subjects 27 . The role of DLco in pulmonary function testing is to provide information on the transport of gas from alveolar air to hemoglobin 28 .…”

Efeitos de um programa de reabilitação pulmonar sobre mecânica respiratória e qualidade de vida de mulheres obesas

“…Azeredo (24), em estudo que combinou os exercícios aeróbicos com alongamentos e exercícios ventilató-rios diafragmáticos, obteve resultados que favoreceram o reequilíbrio da musculatura inspiratória e expiratória minimizando as alterações decorrentes da debilidade muscular, estimulando a atividade diafragmática e, assim, promovendo aumento do VC. Outro estudo relacionado com a prática de exercí-cios globais associados aos exercícios respiratórios dentro de um programa de reabilitação por meio da reeducação postural global, no período de 8 semanas, em jovens saudáveis e sedentários, ocasionou melhora significativa nas pressões respiratórias má-ximas e na mobilidade tóraco-abdominal (25).…”
