与红花粉 (POM) 结合甜菜汁 (BR) 并没有提高,并且可能稍微降低,与单独使用BR相比,爆炸性炼性能. 单独补充甜菜汁也对抵抗运动产生了有限的益处.
科学领域:
- 运动科学 运动科学 运动科学
- 营养生物化学 营养生物化学
- 运动生理学 运动生理学
背景情况:
- 已知饮食中的酸盐 (NO3-) 可以提高运动表现.
- 甜菜汁 (BR) 是一个丰富的酸盐来源.
- 石榴 (POM) 含有抗氧化剂和多,但其与酸盐对运动表现的影响不太清楚.
研究的目的:
- 研究富含酸盐的甜菜汁 (BR) 和石榴粉 (POM) 对神经肌肉性能的联合作用.
- 为了比较单独的BR与BR+POM补充剂的效果.
- 评估对垂直跳跃,爆炸性俯卧和背的影响.
主要方法:
- 一项双盲,随机,交叉研究,对15名娱乐活跃的男性进行.
- 三个条件:安慰剂 (PL),甜菜汁 (BR) 和甜菜汁+石榴粉 (BR+POM).
- 测量包括血中酸盐/酸盐水平和反运动跳跃,跪和背的表现.
主要成果:
- 与安慰剂相比,BR和BR + POM的血亚酸盐和亚酸盐水平显著增加.
- 与BR + POM相比,反运动跳跃的峰值功率在BR + POM中高出3%,但与安慰剂没有显著差异.
- 在爆炸性跪俯卧或背之间没有观察到显著的性能差异.
结论:
- 单独使用BR或与POM结合使用BR的补充剂对抵抗运动的人体营养潜力有所限制.
- 与BR单独相比,将BR与POM相结合可能会损害抵抗运动表现的各个方面.
- 酸盐补充剂显示出调节爆炸性运动表现的潜力,但添加POM需要谨慎.

Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
Exercise and Muscle Performance
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...
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...
