All the subjects performed two treadmill ergoespirometry tests : first , a modified Bruce protocol to discard ischemic responses during exercise and to evaluate VO@max before the experimental phase ; and second , with an eccentric protocol ( @ % descending ramp test ) during @ minutes in stable state at @-@ % VO@max , as experimental inflammatory protocol.We compared intra and inter groups to evaluate differences in the pre and post-test differences results on blood muscle damage variables .
