AB  - The aim of this study was to evaluate the changes in pressure pain sensitivity 
      maps in untrained subjects over 2 subsequent sessions of eccentric exercise (ECC) 
      expected to result in (a) delayed onset muscle soreness (DOMS) and (b) 
      adaptation/recovery, respectively. Eleven healthy male subjects participated in 
      this study. Pressure pain threshold (PPT), rate of perceived exertion (RPE), pain 
      intensity, soreness area drawing, maximal voluntary contraction (MVC), and 
      shoulder range of motion were assessed in session 1 before, immediately after, 
      and 24 hours after ECC. The ECC protocol that was used to induce DOMS consisted 
      of 50 eccentric contractions of the right shoulder that were divided into 5 
      bouts, including 10 contractions at MVC level separated by a 2-minute resting 
      period. Session 2 was identical to session 1 and performed exactly 1 week later. 
      There was only a significant increase in the RPE assessed before the exercise and 
      24 hours after the exercise in session 1 (p = 0.001). The average PPT only 
      decreased significantly from before the exercise (660.2 +/- 76.2 kPa) to 24 hours 
      after the exercise (435.6 +/- 59.3 kPa) in session 1 (p = 0.016). The present study 
      confirmed a heterogeneous distribution of mechanical sensitivity before and after 
      sessions of ECC. The first session of ECC underlined increased mechanical 
      sensitivity because of DOMS, whereas the second session reflected an adaptation 
      process. Our results support the potential role of ECC bouts in training 
      regimens.
