【 摘 要 】

Minahan et al. (2015) recently published a study that examined respiratory strength using a new device, POWERbreathe K5, before and after a strenuous exercise, in comparison with an well-established maneuver to evaluate the maximum inspiratory pressure (MIP).In this study, authors have compared a dynamic evaluation of the inspiratory muscles (S-Index) with a quasi-isometric evaluation (MIP) including a scientific rational about an isokinetic and isometric limb muscles evaluation, even considering that the S-index is not an isokinetic parameter.The authors did not find respiratory muscle fatigue evaluated by these two different parameters before and after whole body exercise protocol. However, the present results may have been influenced by two confounders: 1) The exercise protocol used to induce respiratory muscle fatigue and 2) The learning effect of the test.
