概括
耐力跑步并没有改变群体层面的疼痛敏感性,但疼痛的时间总和减少了. 个体疼痛调节反应各不相同,这表明需要个性化炼策略来控制疼痛.
科学领域:
- 运动生理学 运动生理学
- 疼痛科学 疼痛科学
- 神经科学是一个神经科学.
背景情况:
- 有氧运动通常会诱导短暂的低痛症 (疼痛减轻).
- 对于在长期耐力活动中对抗痛药效应的了解有限.
- 这项研究调查了长距离跑步机跑步期间的运动诱导的低性痛症 (EIH).
研究的目的:
- 为了检查健康个体在15公里跑步机跑步期间的EIH反应.
- 评估疼痛敏感度指标的变化,包括疼痛压力值 (PPT),袖口PPT (cPPT),袖口压力疼痛耐受度值 (cPTT),疼痛时间总和 (TSP) 和条件疼痛调制 (CPM).
- 通过基于PPT变化识别不同的子组来探索EIH的个体变化.
主要方法:
- 30名健康的参与者 (18-50岁) 进行了15公里的跑步机跑步.
- 在运行前和运行期间使用PPT,cPPT,cPTT,TSP和CPM测量疼痛敏感度.
- 隐性增长混合模型和后勤回归被用于探索性亚组分析和亚组成员的预测.
主要成果:
- 对于PPT,PTT,cPPT或CPM,随着时间的推移,没有发现显著的组级变化.
- 与基线相比,TSP在10公里和15公里后显著下降.
- 确定了两个不同的子组 ("增加PPT"和"减少PPT"),基线CPM和EIH预测子组成员.
结论:
- 在小组层面上,有氧运动没有显著改变PPT,cPPT或CPM,但TSP下降.
- 在耐力运动期间,疼痛调节的个体变异性至关重要.
- 识别不同的低疼痛缓解特征可以为个性化炼干预和疼痛管理策略提供信息.

1.5K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.
