概括
骑自行车者和跑步者表现出明显的肠道微生物组特征,与跑步者相比,男性骑自行车者的多样性较低. 特定的肠道细菌与两组运动员的表现指标相关,这表明了运动特定的微生物特征.
科学领域:
- 人类肠道微生物组研究研究
- 运动生理学 运动生理学
- 运动特定的适应.
背景情况:
- 之前的研究表明,肠道微生物群与跑步者的体育相关,在两性之间显示出相似的多样性.
- 除了像骑自行车运动员这样的跑步运动员之外,耐力运动员的肠道微生物组组成仍未得到充分研究.
- 了解体育特定的肠道微生物特征对于优化运动表现和健康至关重要.
研究的目的:
- 与跑步者相比,研究竞争性自行车运动员的肠道微生物组概况.
- 为了确定肠道微生物群的特征是否与运动有关.
- 为了确定男性和女性骑自行车和跑步者的微生物组合的差异.
- 探索肠道细菌与骑自行车者和跑步者的运动表现指标之间的相关性.
主要方法:
- 招募了58名参与者:18名骑自行车者,22名跑步者和18名对照者 (注明性别分布).
- 收集了用于16S rRNA测序的便样本,以分析肠道微生物群的组成和多样性 (α和β).
- 通过最大氧气消耗 (VO2max) 和耗尽时间测试来评估运动表现,测量血液中乳酸盐水平.
主要成果:
- 在骑自行车者和跑步者之间观察到阿尔法多样性的显著差异 (p-adj < 0.001).
- 与男性跑步者相比,男性骑自行车的人表现出明显较低的α多样性 (p-adj < 0.001).
- 15种不同的细菌在骑自行车者,跑步者和对照者之间表现出不同的丰度.
- 在骑自行车者 (6种细菌) 和跑步者 (8种细菌) 中,特定的肠道细菌与训练量,耗尽时间,VO2max和血液乳酸盐水平之间发现了积极的相关性.
结论:
- 肠道微生物组的特征似乎是体育特异性的,在骑自行车者和跑步者之间存在差异.
- 骑自行车者和跑步者之间存在着不同的肠道细菌组成和多样性水平.
- 这些差异很可能受到骑自行车与跑步独特的生理和生物力学需求的影响.

71.3K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

377
The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.
