To compare the predictive capacity of experimental pain and exercised-induced pain (EIP) on exercise performance. Thirty-two recreationally active male (n = 23) and female (n = 9) participants were recruited. Participants completed measures of pain tolerance by cold pressor test (CPT), pain pressure threshold via algometry (PPT), and EIP tolerance using an RPE clamp trial. A VO_2max test provided traditional predictors of performance [VO_2max, gas-exchange threshold‎ (GET), peak power output (PPO)]. Finally, participants completed a 16.1-km cycling time trial (TT). No correlation was found between experimental pain measures (CPT, PPT) and TT performance. However, there was a significant correlation between EIP tolerance and TT performance (R = −0.83, P < 0.01). Regression analysis for pain and physiological predictor variables (mean pain in CPT, PPT, EIP tolerance, VO_2max, PPO, GET) revealed that a significant model (P < 0.01) emerged when only PPO (Adjusted R² = 0.739) and EIP tolerance (ΔR² = 0.075) were used to predict TT performance. These findings suggest that EIP tolerance is an important factor in endurance performance. However, PPT and CPT have limited ability to assess this relationship, and so their use in EIP research should be treated with caution.
