Physical activity modifies the gut microbiota, exerting health benefits on the host; however, the specific bacteria associated with exercise are not yet known. In this work, we propose a novel method, based on hierarchical topology, to study the differences between the microbiota of active and sedentary lifestyles, and to identify relevant bacterial taxa. Our results show that the microbiota network found in active people has a significantly higher overall efficiency and higher transmissibility rate. We also identified key bacteria in active and sedentary networks that could be involved in the conversion of an active microbial network to a sedentary microbial network and vice versa.
体育活动可改变肠道微生物群，对宿主产生健康益处；然而，与运动相关的特定细菌尚不清楚。在这项工作中，我们提出了一种基于层次拓扑的新方法，以研究活跃和久坐生活方式的微生物群之间的差异，并识别相关的细菌分类群。我们的结果表明，活跃人群中发现的微生物群网络具有显著更高的整体效率和更高的传播率。我们还确定了活跃和久坐网络中的关键细菌，它们可能参与活跃微生物网络与久坐微生物网络之间的转换，反之亦然。
