The current study aimed to investigate if the gut microbiota composition of elite female football players changes during an official international tournament. The study was conducted throughout ten consecutive days, encompassing seven training sessions, and three official matches. The matches were separated by 48-72 h. Seventeen elite female football players from the Portuguese women's national football team participated in the study. Fecal samples were collected at two time points: at the beginning and end of the tournament. Fecal microbiota was analyzed by sequencing the 16S rRNA gene. Throughout the study, the duration and rating of perceived exertion (RPE) were recorded after training sessions and matches. The internal load was determined by the session RPE. The gut microbiota of players was predominantly composed of bacteria from the phyla Firmicutes (50% of relative abundance) and Bacteroidetes (20%); the genera Faecalibacterium (29%) and Collinsella (16%); the species Faecalibacterium prausnitzii (30%) and Collinsella aerofaciens (17%). Overall, no significant changes were observed between time points (p ≥ 0.05). Also, no relationship was found between any exercise parameter and the gut microbiota composition (p ≥ 0.05). These findings demonstrate that the physical and physiological demands of training and matches of an official international tournament did not change the gut microbiota composition of elite female football players. Furthermore, it supports that the gut microbiota of athletes appears resilient to the physical and physiological demands of training and match play.
本研究旨在探究精英女性足球运动员在国际正式比赛期间肠道微生物组成是否发生变化。研究持续了十天，包括七次训练和三次正式比赛。比赛之间间隔 48-72 小时。17 名来自葡萄牙女足国家队的精英女性足球运动员参与了这项研究。在研究开始和结束时，分别采集了两次粪便样本。通过 16S rRNA 基因测序分析粪便微生物群。在整个研究过程中，记录了训练和比赛后的训练和比赛后持续时间和感知用力（RPE）。内部负荷由 RPE 决定。球员的肠道微生物群主要由厚壁菌门（相对丰度的 50%）和拟杆菌门（20%）组成；粪杆菌属（29%）和柯林斯氏菌属（16%）；粪杆菌 prausnitzii 种（30%）和柯林斯氏 Aerofaciens 种（17%）。总体而言，两个时间点之间没有观察到显著变化（p≥0.05）。此外，任何运动参数与肠道微生物群组成之间都没有发现关系（p≥0.05）。这些发现表明，正式国际比赛的训练和比赛的生理和生理需求并没有改变精英女性足球运动员的肠道微生物组成。此外，它支持运动员的肠道微生物群对训练和比赛的生理和生理需求具有很强的抵抗力。
