“…The techniques to rehabilitate breathing include lowering excess muscle tone activity in the inspiratory chain, gradually increasing inhalation until the threshold, and optimising the breathing pattern (training in slow exhalation) (Chaitow et al, 2014). In this sense, several studies on sedentary people have confirmed the effectiveness of GPR in improving the respiratory function and the active strength of the inspiratory musculature, returning flexibility to the inspiratory chain through soft, slow breathing (Alonso Blanco, López, & Peñas, 2009;Moreno et al, 2007;Moreno, Catai, Teodori, Borges, & Zuttin, 2009;Teodori, Moreno, Fiore Junior, & Oliveira, 2003).…”
