等长运动后疼痛敏感性降低。目前尚不清楚这种运动引起的痛觉减退（EIH）是否在男性和女性中发生的程度相同。目前还不清楚这种影响是全身性的还是局部的。本研究的目的是调查是否疲劳的脊柱和髋关节伸肌等长运动会导致增加的压力疼痛阈值（PPT）在本地和远程的健康男性和女性的运动肌肉的网站，以及是否有中枢敏感化，心理社会因素，和PPT之间的关系。 35名健康成人（年龄27.1 ± 4.5岁，22名女性）。 这是一项受试者内队列研究。参与者完成了量化中枢致敏、疼痛灾难化、嗜睡/失眠、焦虑和抑郁的问卷。在参与者进行Biering-Sorensen测试失败之前和之后立即评估腰椎和胸椎椎旁肌、腿筋、腓肠肌、腕关节和第三趾的PPT。 运动后PPT在男性和女性的胸椎椎旁肌、腘绳肌和腓肠肌中增加，仅在男性的腰椎椎旁肌中增加，但在手腕和手指部位没有变化。基线时平均PPT较低与中枢致敏评分较高相关。疲劳后平均PPT的较大增加与基线时较高的平均PPT显著相关。 运动诱发的痛觉减退发生在疲劳运动中涉及的肌肉上的部位，而不是在远处的部位，并且在男性中比女性更明显。EIH的大小取决于基线PPT。即使在健康个体中，更高的中枢致敏性也与较低的基线PPT相关。
Pain sensitivity decreases following isometric exercise. It is not clear whether this exercise-induced hypoalgesia (EIH) occurs to the same extent in men and women. It is also unclear if the effect is systemic or local to the exercised musculature. The aim of our study was to investigate whether fatiguing isometric exercise of the spinal and hip extensors would result in increased pressure pain threshold (PPT) at sites local to and remote from the exercised muscles in healthy men and women and whether there is a relationship between central sensitization, psychosocial factors, and PPT. 35 healthy adults (age 27.1 ± 4.5 years, 22 women). This was a within-subjects cohort study. Participants completed questionnaires quantifying central sensitization, pain catastrophizing, sleepiness/insomnia, anxiety, and depression. PPT was assessed at the lumbar and thoracic paraspinals, hamstrings, gastrocnemius, wrist, and third digit before and immediately after participants performed the Biering–Sorensen test to failure. PPT increased postexercise in the thoracic paraspinals, hamstrings, and gastrocnemius in men and women and in the lumbar paraspinals in men only but did not change at the wrist and digit sites. A lower average PPT at baseline was associated with a higher central sensitization scores. A greater increase in average PPT postfatigue was significantly associated with higher average PPT at baseline. Exercise-induced hypoalgesia occurs at sites overlying the muscles involved in fatiguing exercise, but not at remote sites, and is more evident in males than females. The magnitude of EIH depends upon baseline PPT. Even in healthy individuals, greater central sensitization is associated with lower baseline PPT.
