“The effects of a variety of restrictive procedures on lung mechanics were studied in eight healthy subjects.”


“Lung volume restriction induces changes in lung function, but the nature of these changes depends on how the restriction is applied and therefore cannot be ascribed to low lung volume breathing per se.”

Protective equipment that restricts lung function can increase breathing effort and reduce operational performance. POWERbreathe Inspiratory Muscle Training reverses these impairments.
