概括
运动训练增强了对胆固醇激动剂的出汗反应. 氧化合成酶 (NOS) 在耐力训练的男性中部分导致这种增强的出汗,正如L-NAME所示.
科学领域:
- 身体生理学 身体生理学
- 运动科学 运动科学
- 热调节 热调节 热调节
背景情况:
- 在训练过的个体中,增强胆激素激剂诱导的出汗并未完全被理解.
- 氧化合成酶 (NOS) 在这种增强的出汗反应中的作用需要研究.
研究的目的:
- 调查一项假设,即氧化合成酶 (NOS) 导致常规运动训练的个体增加皮洛卡尔宾诱导的出汗.
主要方法:
- 耐力训练和未训练的男性 (每人n=15) 接受了前臂离子透,使用L-NAME (一种NOS抑制剂) 或盐水 (对照).
- 皮洛卡尔 (0.001%和1%) 用于评估出汗率.
- 测量出汗率是为了评估NOS抑制对胆固醇出汗的影响.
主要成果:
- 在运动训练的男性中,L-NAME的使用显著减轻了10%的皮洛卡尔宾诱导的出汗 (P=0.004).
- 在未受过训练的个体中没有观察到 significant 显著减轻出汗的情况 (P=0.764).
- 这种效应与皮洛卡尔宾度无关.
结论:
- 氧化合成酶 (NOS) 部分导致运动训练的男性观察到的胆固醇出汗增加.
- 这一发现阐明了运动员增强热调节背后的生理机制.
- 准NOS途径可能为调节出汗反应提供了洞察力.

Nitric Oxide Signaling Pathway
4.9K
Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure...

Antihypertensive Drugs: Vasodilators
479
Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...
