Abstract：
Exercise-Induced Hypoalgesia (EIH) refers to an acute reduced pain perception after exercise. This systematic review and meta-analysis investigated the effect of a single aerobic exercise session on local and remote EIH in healthy individuals, examining the role of exercise duration, intensity, and modality. Pressure pain thresholds (PPT) are used as the main measure, applying the Cochrane risk of bias tool and GRADE approach for certainty of evidence assessment. Mean differences (MD; Newton/cm²) for EIH effects were analysed. Thirteen studies with 23 exercises and 14 control interventions are included (498 participants). Most studies used bicycling, with only two including running/walking and one including rowing. EIH occurred both locally (MD = 3.1) and remotely (MD = 1.8), with high-intensity exercise having the largest effect (local: MD = 7.5; remote: MD = 3.0) followed by moderate intensity (local: MD = 3.1; remote: MD = 3.0). Low-intensity exercise had minimal impact. Neither long nor short exercise duration induced EIH. Bicycling was found to be effective in eliciting EIH, in contrast to the limited research observed in other modalities. The overall evidence quality was moderate with many studies showing unclear risk biases.
摘要：
运动诱发的痛觉减退(EIH)是指运动后疼痛感觉的急性降低。这项系统评价和荟萃分析调查了健康个体中单次有氧运动对本地和远程EIH的影响。检查运动持续时间的作用，强度,和模态。以压力痛阈值(PPT)为主要衡量标准,应用Cochrane偏差风险工具和GRADE方法进行证据确定性评估。分析了EIH效应的平均差(MD;牛顿/平方厘米)。包括13项研究，包括23项练习和14项控制干预措施（498名参与者）。大多数研究使用骑自行车，只有两个包括跑步/步行，一个包括划船。EIH发生在本地（MD=3.1）和远程（MD=1.8），高强度运动效果最大（局部：MD=7.5；远程：MD=3.0），其次是中等强度（局部：MD=3.1；远程：MD=3.0）。低强度运动的影响很小。运动持续时间长或短都不会引起EIH。发现骑自行车可以有效地引发EIH，与其他模式中观察到的有限研究相反。总体证据质量适中，许多研究显示风险偏差不明确。
