消耗氧气纳米泡水 (NBO2W) 在运动期间改善了乳酸值 (LT) 的工作速度. 然而,NBO2W并没有提高峰值运动能力,也没有影响血液乳酸积累的开始.
科学领域:
- 运动生理学 运动生理学
- 运动科学 运动科学 运动科学
- 营养补充剂 营养补充剂
背景情况:
- 乳酸值 (LT) 是有氧运动表现的关键决定因素.
- 富含氧气饮料,如纳米氧气纳米泡水 (NBO2W) 对炼指标的影响尚未得到充分证实.
- 了解NBO2W的影响可以为提高运动能力的策略提供信息.
研究的目的:
- 调查NBO2W摄入量对成人乳酸值 (LT) 的影响.
- 评估NBO2W对峰值运动能力和血液乳酸动态的影响.
- 为了评估NBO2W作为潜在的人体营养辅助剂的有效性.
主要方法:
- 一个双盲,随机,安慰剂控制的交叉试验,涉及20名参与者.
- 参与者在增量运动测试前消耗了NBO2W或安慰剂水 (PW).
- 持续监测心率,气体交换 (VO2,VCO2),组织氧气指数 (TOI) 和血液乳酸盐水平.
主要成果:
- 与PW相比,在NBO2W摄入后,LT的工作率明显高于PW (p=0.03).
- 血中乳酸蓄积开始时的VO2峰值和工作率在条件之间没有显著差异.
- 摄入NBO2W增加了运动后的乳酸水平 (p=0.01) 和降低了组织氧指数 (p=0.01).
结论:
- 短期NBO2W消费改善了乳酸值的工作率.
- 在这个群体中,NBO2W并没有提高峰值运动能力.
- 需要进一步的研究来阐明NBO2W对运动表现的影响背后的生理机制.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...
