摘要
本研究旨在探讨在最大限度间歇性跑步运动前后,急性摄入富含硝酸盐(NO3-)的甜菜根汁对爆发力和高强度运动表现、口腔微生物群组成以及认知灵活性(即功能)的影响。通过随机、双盲、交叉设计,15名女子团队运动运动员在进行一系列运动表现任务和认知测试之前和之后,分别在2.5小时内饮用浓缩的缺NO3甜菜根汁(PL;0.1毫摩尔NO3-)和富含NO3的甜菜根汁(BR;12.0毫摩尔NO3-)。静息血浆[NO3-]和血浆亚硝酸盐([NO2-])在BR(P 0.05)或运动前后的认知灵活性(P > 0.05)后升高。在 20 米(运动前,PL:4.38 ± 0.27 vs. BR:4.38 ± 0.32 秒;运动后,PL:4.45 ± 0.29 vs. BR:4.43 ± 0.35 秒)和 10 米短跑(运动前,PL 2.78 ± 0.15 vs. BR 2.79 ± 0.18 s; POST, PL: 2.82 ± 0.16 vs. BR: 2.81 ± 0.19 s)、等速手握测力、掷药球、水平反向运动跳跃或 YYIR1(PL: 355 ± 163 m vs. BR: 368 ± 184 m)在 BR 和 PL 之间的差异(P > 0.05)。这些研究结果表明,急性膳食 NO3- 可能不会影响女子团队运动运动员的口腔微生物组、爆发力和高强度运动表现或认知功能。
Acute inorganic nitrate ingestion does not impact oral microbial composition, cognitive function, or high-intensity exercise performance in female team-sport athletes.
The purpose of this study was to investigate the effects of acute nitrate (NO3-)-rich beetroot juice ingestion on explosive and high-intensity exercise performance, oral microbiota composition, and cognitive flexibility (i.e., function), before and after maximal intermittent running exercise. Fifteen women team-sport athletes were assigned in a randomized, double-blind, crossover design to consume concentrated NO3--depleted beetroot juice (PL; 0.1 mmol NO3-) and NO3--rich beetroot juice (BR; 12.0 mmol NO3-) 2.5 h prior to performing a battery of exercise performance tasks and cognitive testing before and after the Yo-Yo intermittent recovery level 1 (YYIR1) running test. Resting plasma [NO3-] and plasma nitrite ([NO2-]) were elevated following BR (P < 0.001). BR did not impact global composition or relative abundance of taxa in the oral microbiome (P > 0.05) or cognitive flexibility before or after exercise (P > 0.05). There was no significant difference in performance during 20-m (PRE, PL: 4.38 ± 0.27 vs. BR: 4.38 ± 0.32 s; POST, PL: 4.45 ± 0.29 vs. BR: 4.43 ± 0.35 s) and 10-m sprints (PRE, PL 2.78 ± 0.15 vs. BR 2.79 ± 0.18 s; POST, PL: 2.82 ± 0.16 vs. BR: 2.81 ± 0.19 s), isokinetic handgrip dynamometry, medicine ball throw, horizontal countermovement jump, or YYIR1 (PL: 355 ± 163 m vs. BR: 368 ± 184 m) between BR and PL (P > 0.05). These findings indicate that acute dietary NO3- may not influence the oral microbiome, explosive and high-intensity exercise performance, or cognitive function in women team-sport athletes.
期刊介绍:
The European Journal of Applied Physiology (EJAP) aims to promote mechanistic advances in human integrative and translational physiology. Physiology is viewed broadly, having overlapping context with related disciplines such as biomechanics, biochemistry, endocrinology, ergonomics, immunology, motor control, and nutrition. EJAP welcomes studies dealing with physical exercise, training and performance. Studies addressing physiological mechanisms are preferred over descriptive studies. Papers dealing with animal models or pathophysiological conditions are not excluded from consideration, but must be clearly relevant to human physiology.
