Changes in lung volumes and ventilatory mechanical activity are directly related to chest movements during the respiratory phases, which, together with the ventilatory muscles, coordinate the entry and exit of gases from the lungs. The evaluation of both thoracic expandability and ventilatory musculature has been an important clinical indicator of diseases affecting the respiratory system. The chest and abdomen movements are measured by thoracic-abdominal mobility (MTA) with a tape measure and ventilatory muscle strength by maximal inspiratory and expiratory pressures (MIP and MEP) with the manovacuometer, both during maximal inspiratory and expiratory maneuvers. The systematic review of this dissertation showed that the reviewed studies showed a vulnerability of the methods applied to evaluate ventilatory muscle strength, such as lack of familiarization of MIP and MEP, cross validation and outliers exclusion, resulting in regression equations with low predictive power and did not use the MTA as a predictor variable. The second study after comparing MTA in the orthostatic and decubitus positions and verify their correlation with the MIP and MEP of 276 volunteers of both sexes, showed significant MTA differences when measured in the orthostatic position and in the dorsal decubitus position and a higher correlation with the MIP and MEP in the supine position. The third study developed predictive equations for MIP and MEP from the variables gender, age, total body mass, height and MTA for a healthy population of both sexes, aged between 20 and 79 years, and performed the cross-validation of these equations, making the most reliable
