近年来，随着对增强表现物质的需求的增加，在运动营养方面进行了大量研究。从饮食中摄入更多的硝酸盐可以通过硝酸盐-亚硝酸盐-NO 途径增加一氧化氮 (NO) 的生物利用度。然而，一氧化氮可用性的增加并不总能改善某些个体的表现。本综述旨在评估运动员训练状态与增加膳食硝酸盐摄入量后计时赛成绩变化之间的关系。审查了 2015 年至 2019 年发表的 Scopus 和 PubMed 索引的文章。 13篇文章符合入选标准：对不同训练状态的健康参与者（根据VO2max）进行临床试验研究，在膳食硝酸盐补充剂后进行计时试验。审查过程遵循 PRISMA 指南。我们发现，在训练较少的运动员（VO2 < 55 mL/kg/min）中，使用单向方差分析 (p = 0.001)，最大摄氧量与计时赛表现中的力源性之间存在统计显着关系。在使用长期补充方案的实验情况下观察到强烈的正相关性，但在急性方案情况下却没有观察到。根据我们的结果和最近对肌肉纤维的组织学观察，纤维类型可能在一氧化氮的产生中发挥特定作用，因此补充麦角作用。
Much research has been done in sports nutrition in recent years as the demand for performance-enhancing substances increases. Higher intake of nitrates from the diet can increase the bioavailability of nitric oxide (NO) via the nitrate–nitrite–NO pathway. Nevertheless, the increased availability of NO does not always lead to improved performance in some individuals. This review aims to evaluate the relationship between the athlete’s training status and the change in time trial performance after increased dietary nitrate intake. Articles indexed by Scopus and PubMed published from 2015 to 2019 were reviewed. Thirteen articles met the eligibility criteria: clinical trial studies on healthy participants with different training status (according to VO2max), conducting time trial tests after dietary nitrate supplementation. The PRISMA guidelines were followed to process the review. We found a statistically significant relationship between VO2max and ergogenicity in time trial performance using one-way ANOVA (p = 0.001) in less-trained athletes (VO2 < 55 mL/kg/min). A strong positive correlation was observed in experimental situations using a chronic supplementation protocol but not in acute protocol situations. In the context of our results and recent histological observations of muscle fibres, there might be a fibre-type specific role in nitric oxide production and, therefore, supplement of ergogenicity.
