AbstractThe ability of athletes to continue to compete despite sustaining painful injury is often interpreted as evidence for the activation of endogenous analgesia mechanisms. However, alterations in perception of noxious stimuli during competition have not yet been systematically investigated. This experiment evaluated experimental pain sensitivity in male and female athletes 2 days before, immediately following, and 2 days after competition. Non-athlete controls were evaluated at the same intervals. Competition dramatically reduced pain report on the cold-pressor test in all athletes. Withdrawal latencies to noxious heat also were altered by competition, with finger withdrawal latency decreasing and arm withdrawal latency increasing in most athletes. No changes in pain report were observed across time in non-athlete controls. Competition induces both hyperalgesic and analgesic states that are dependent on the body region tested and pain assessment methodology used.
