      <subfield code="a">The objetive of this study was to identify the perceived exertion mechanisms (direct muscle force and whole body exertion) associated with the decision to change the weight of lift during the detemination of the maximum acceptable weight of lift (MAWL). Collectively, these findings indicate that psychophysically determined weight limits may be more sensitive to muscular strain rather than spinal loading</subfield>
