The aim of the current study was to examine the relationship between pain modulatory capacity and endurance exercise performance. Twenty-seven recreationally active males between 18 and 35 years of age participated in the study. Pain modulation was assessed by examining the inhibitory effect of a noxious conditioning stimulus (cuff occlusion) on the perceived intensity of a second noxious stimulus (pressure pain threshold). Participants completed two, maximal voluntary contractions followed by a submaximal endurance time task. Both performance tasks involved an isometric contraction of the non-dominant leg. The main analysis uncovered a correlation between pain modulatory capacity and performance on the endurance time task (r = -.425, p = .027), such that those with elevated pain modulation produced longer endurance times. These findings are the first to demonstrate the relationship between pain modulation responses and endurance exercise performance.
本研究的目的是检验疼痛调节能力与耐力运动表现之间的关系。27名年龄在18至35岁之间的有休闲运动习惯的男性参与了该研究。通过检查有害条件刺激（袖带阻断）对第二种有害刺激（压力疼痛阈值）的感知强度的抑制作用来评估疼痛调节。参与者完成了两次最大自主收缩，随后进行了次最大耐力时间任务。两项表现任务均涉及非优势腿的等长收缩。主要分析发现疼痛调节能力与耐力时间任务的表现之间存在相关性（r = -0.425，p = 0.027），即疼痛调节能力增强的人耐力时间更长。这些发现首次证明了疼痛调节反应与耐力运动表现之间的关系。
