Dietary nitrate supplementation increases circulating nitrite concentration, and the subsequent reduction of nitrite to nitric oxide is promoted in hypoxic environments. Given that PO2 is lower in Type II compared with Type I muscle, this article examines the hypothesis that the ergogenicity of nitrate supplementation is linked to specific effects on vascular, metabolic, and contractile function in Type II muscle.
饮食硝酸盐补充会增加循环中亚硝酸盐的浓度，而在缺氧环境中，亚硝酸盐随后会被还原为一氧化氮。由于 II 型肌中的 PO2 比 I 型肌低，因此本文探讨了这样一种假设，即硝酸盐补充的功效与 II 型肌中对血管、代谢和收缩功能的特定影响有关。
