AB  - We sought to determine the effects of blood flow restriction (BFR) on 
      exercise-induced hypoalgesia, specifically using low-load (LL) resistance 
      exercise (30% 1RM) protocols that accounted for each individual's local muscular 
      endurance capabilities. Forty-four participants completed four conditions: (1) 
      70% of maximal BFR repetitions with blood flow restriction (LL+BFR exercise); (2) 
      70% maximal BFR repetitions without LL+BFR (LL exercise); (3) 70% maximal free 
      flow repetitions (LL+EFFORT exercise); (4) time-matched, non-exercise control 
      (CON). Pressure pain threshold (PPT) was measured before and after exercise. 
      Ischaemic pain threshold and tolerance was assessed only at post. The change in 
      upper body PPT was greater for LL+BFR exercise compared to LL exercise 
      [difference of 0.15 (0.35) kg/cm(2)], LL+EFFORT exercise [difference of 0.23 
      (0.45) kg/cm(2)], and the CON condition. The change in lower body PPT was greater 
      for LL+BFR exercise compared to LL exercise [difference of 0.40 (0.55) kg/cm(2)], 
      LL+EFFORT exercise [difference of 0.36 (0.62) kg/cm(2)], and the CON condition. 
      Ischaemic pain thresholds and tolerances did not change. Submaximal exercise with 
      BFR resulted in systemic increases in PPT but had no influence on ischaemic pain 
      sensitivity. This effect is likely unique to BFR as we did not see changes in the 
      effort matched free flow condition.
