Gut enterotypes in elite and youth non-elite athletes. A total of 306 samples are stratified into three enterotypes. The major contributor in the three enterotypes is Prevotella, Bacteroides and Ruminococcaceae_unclassified, respectively. (a) Relative abundances of the top genera (Prevotella, Bacteroides and Ruminococcaceae_unclassified) in each enterotype. (b) Three enterotypes were visualized by PCoA of Jensen-Shannon distance at the genus level. (c) The proportion of AE, YE and YN samples distributed in three enterotypes. 72.3% AE, 61.9% YE and 27.27% YN samples are found in enterotype 3. (d) Co-occurrence patterns among the dominant genera (average relative abundance > 0.01%) across the samples from enterotype 3, as determined by the Spearman correlation analysis
