AB  - PURPOSE: This cross-sectional study aimed to investigate whether psychosocial 
      factors were predictive for exercise-induced hypoalgesia (EIH) in pain-free 
      adults. METHODS: A sample of 38 pain-free nurses with a mean (SD) age of 26 (6) 
      years were included in this study. Participants completed psychosocial 
      questionnaires prior to physical tests. Pressure pain threshold (PPT) was 
      assessed bilaterally at the calves (local), lower back (semi-local) and forearm 
      (remote) before and immediately after a maximal graded cycling exercise test. 
      Separate linear mixed effects models were used to determine change in PPT before 
      and after cycling exercise (EIH). Multiple linear regression for all psychosocial 
      variables and best subset regression was used to identify predictors of EIH at 
      all locations. RESULTS: The relative mean increase in PPT at the forearm, lumbar, 
      calf, and globally (all sites pooled) was 6.0% (p<0.001), 10.1% (p<0.001), 13.9% 
      (p<0.001), and 10.2% (p=0.013), respectively. Separate best subset multiple 
      linear regression models at the forearm (predictors; Multidimensional Scale of 
      Perceived Social Support (MSPSS) total), lumbar (predictors; MSPSS total, Pain 
      Catastrophizing Scale (PCS) total, Depression Anxiety Stress Scale (DASS) 
      depression), calf (predictors; MSPSS friends, PCS total), and global (predictors; 
      MSPSS friends, PCS total) accounted for 7.5% (p=0.053), 13% (p=0.052), 24% 
      (p=0.003), and 17% (p=0.015) of the variance, respectively. CONCLUSION: These 
      findings confirm that cycling exercise produced EIH in young nurses and provided 
      preliminary evidence to support the interaction between perceived social support, 
      pain catastrophizing and EIH. Further investigation is required to better 
      understand psychological and social factors that mediate EIH on a larger sample 
      of adults at high risk of developing chronic musculoskeletal pain.
