dc.description.abstractPurpose: The aim of this experiment was to investigate if a warm-up period prior to eccentric exercise has a preventive effect on the increased sensitivity to pain, and the loss of force, associated with delayed onset muscle soreness (DOMS). Methods: Twenty-four subjects were randomly assigned into a warm-up group (N=12) or a control group (N=12). The warm-up group completed 20 minutes of ergometer cycling, with an intensity of 60-70 % of estimated maximal heart rate, prior to eccentric exercise, while the control group did not perform warm-up prior to the eccentric exercise. DOMS was induced by completing 5 sets of 10 forward lunges (eccentric exercise). The outcome measures were: subjective evaluation of pain on a 100 mm. visual analogue scale (VAS), a pressure-pain threshold (PPT) on various locations of the m. rectus femoris, and isometric maximal voluntary contraction force (MVC), collected prior to exercise, 24-and 48 hours following exercise. Results: Both groups had significantly lower PPT in the distal region of the m. rectus femoris 24 hours following eccentric exercise. However, only the control group had a significant decrease in PPT in the proximal region of the m. rectus femoris. In addition, the warm-up group developed significantly less pain than the control group in the proximal region of the m. rectus femoris between baseline and 24 hours following exercise. Both groups had a significant decrease in MVC, and more pain (VAS) following exercise. Moreover, there were no significant differences between groups in MVC and VAS 24 and 48 hours following exercise. Conclusion: Our results suggest that warm-up prior to eccentric exercise might have a preventive effect on DOMS measured as the pressure pain threshold. The preventive effect seems to be most prominent in the proximal region of the muscle 24 hours following exercise.
