概括
抵抗运动可以局部减少疼痛. 这项研究发现,动态阻力运动在运动肌肉中局部增加了热痛值,但没有显示系统性疼痛减轻效应.
科学领域:
- 运动生理学 运动生理学
- 疼痛感知 疼痛感知
- 神经肌肉功能 神经肌肉功能
背景情况:
- 众所周知,动态抵抗运动调节疼痛感知,可能提供局部和全身止痛.
- 对抵抗运动后疼痛调节的研究,特别是对各种刺激和运动类型的疼痛调节的研究,仍然有限.
- 了解局部与全身疼痛变化对于运动处方和疼痛管理至关重要.
研究的目的:
- 调查上半身和下半身动态阻力运动对热疼痛值 (HPT) 和压力疼痛值 (PPT) 的局部和全身影响.
- 为了比较运动和非运动部位疼痛敏感度的变化,遵循不同的阻力运动方案.
- 为了确定急性抵抗运动是否会根据刺激类型 (热量与压力) 不同地影响外围疼痛敏感性.
主要方法:
- 一项交叉设计研究,涉及28名健康参与者 (21名女性,平均年龄21±4岁).
- 参与者接受了基线定量感官测试和5重复最大 (RM) 测试,以测试肩部压力和腿部伸展.
- 运动后对HPT和PPT的评估是在75%的1-RM下进行的上半身或下半身阻力运动后立即在上半身,四头四和下背部进行的.
主要成果:
- 在腿伸展运动 (p=0.043) 后,在四头四部和在肩压运动 (p=0.02) 后,在骨上观察到HPT局部显著增加.
- 在任何运动条件下,在不运动的部位 (下背部) 检测到HPT或PPT没有显著的系统变化.
- 外围疼痛敏感性,特别是对热刺激的敏感性,在急性抵抗运动后,在局部表现出更好的反应.
结论:
- 剧烈的动态阻力运动会在运动肌肉部位引起局部缺血.
- 在这个队列中,单次进行上肢或下肢阻力运动后,系统性疼痛调节效应并不明显.
- 热痛敏感性在运动后表现出局部变化,这表明外围机制可能主要参与其中.

01:25Analgesia and Pain Management
575
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...

01:27Exercise and Muscle Performance
1.4K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

01:12Local Anesthetics: Adverse Effects
405
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...
