  • Dannecker, E.A., P.D. O'Connor, J.W. Atchison, and M.E. Robinson. Effect of eccentric strength testing on delayed-onset muscle pain. J. Strength Cond. Res. 19(4):888-892. 2005.- This investigation was designed to determine the effect of eccentric strength testing on delayed-onset muscle pain in 20 untrained university students. Initially, eccentric strength testing (5-repetition maximum [5RM]) was performed bilaterally. Next, 1 arm completed 3 sets of 10 eccentric repetitions to induce delayed-onset muscle pain. Then, in a subsequent session, whichever arm previously performed only the 5RM test completed the 5RM test a second time and the 3 sets of 10 eccentric repetitions. Statistical analyses supported significantly increased pain intensity and unpleasantness across 48 hours post-5RM test alone. However, pain intensity and unpleasantness after the eccentric training bouts were significantly lower in the arm that performed 2 5RM tests than the arm that performed only 1. Thus, the eccentric strength testing produced delayed-onset muscle pain and protected against future delayed-onset muscle pain. These effects should be considered when such testing is used in baseline strength assessments.
