Loads would be redistributed among active and passive tissues in a non-optimal manner in fatigue conditions. Therefore, a single tissue might be overloaded with minimal loads and as a result the risk of injury would increase.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>OBJECTIVE:<\/jats:bold>\n                    The goal of this paper was to assess the electromyographic response of trunk extensor and abdominal muscles after trunk extensor muscles fatigue induced by cyclic lifting task.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>METHODS:<\/jats:bold>\n                    This was an experimental study that twenty healthy women participated.
