Abstract

SUMMARY: AN ECCENTRIC MUSCLE ACTION IS DESCRIBED AS A MUSCULAR CONTRACTION OCCURRING WHILE THE MUSCLE IS SIMULTANEOUSLY LENGTHENING. ECCENTRIC MUSCLE ACTIONS CAN BE IMPLEMENTED BY THE STRENGTH AND CONDITIONING SPECIALIST IN A VARIETY OF WAYS TO ACHIEVE A NUMBER OF GOALS FROM INCREASING STRENGTH AND POWER PRODUCTION TO PREVENTION AND REHABILITATION OF INJURY. THE PHYSIOLOGIC RATIONALE AS WELL AS THE LOADING PARAMETERS FOR THESE VARIOUS FORMS OF “ECCENTRIC TRAINING” WILL BE BRIEFLY DISCUSSED IN THIS REVIEW.
