概括
浮动疗法在抵抗运动后没有改变β-endorphin或proenkephalin水平. 这表明阿片类可能无法解释在训练有素的男性中浮动疗法的放松效应.
科学领域:
- 运动生理学 运动生理学
- 神经内分泌学神经内分泌学
- 康复科学 康复科学 康复科学
背景情况:
- 众所周知,浮动限制环境刺激疗法 (Float-REST) 可以缓解肌肉疼痛和疲劳.
- 目前尚不完全了解Float-REST的益处背后的生理机制,特别是内源性阿片类的作用.
研究的目的:
- 在训练有素的男性中,研究Float-REST对经过急性,高强度抵抗运动后的β-endorphin (β-End) 和proenkephalin (ProEnk) 释放的影响.
主要方法:
- 在11名受阻训练的男性中,采用了主题内部的交叉设计.
- 参与者进行了高强度阻力运动 (6x10次背,80%1RM),然后进行1小时的浮动或被动控制恢复.
- 在运动前,运动后立即,以及恢复后1,24和48小时收集血液样本,用于对β-End和ProEnk的ELISA分析.
主要成果:
- 血β-End在浮动和对照条件下显著增加了抵抗后的运动,治疗之间没有显著的差异变化.
- 基法林 (ProEnk) 度保持稳定,并且对运动或浮动疗法的反应没有显著变化.
- 这些发现表明,Float-REST在急性抵抗运动的背景下没有显著调节这些特定的阿片类.
结论:
- 观察到的β-End和ProEnk差异性变化的缺乏表明,这些阿片类可能不是在抵抗训练的男性中Float-REST后报告的深度放松的主要调解者.
- 抵抗运动始终会提高β-End,无论随后的浮动疗法如何.
- 稳定,不响应的ProEnk水平暗示了血液循环中的潜在的膜信号机制.

Analgesia and Pain Management
403
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...

Opioid Analgesics: Synthetic and Semisynthetic Opioids
185
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

Opioid Analgesics: Morphine and Other Natural Cogeners
146
Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...

Opioid Receptors: Overview
368
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...
