There was no difference in the gut microbiota diversity between the controls, bodybuilders, and distance runners. a Comparison of observed species of controls, bodybuilders, and distance runners obtained from 30,000 sequences per sample. b Estimation of the abundance of unique operational taxonomic units (OTUs) using Chao1. Phylogenetic diversity was estimated using the average values for the Chao1 plot of the gut microbiota in the controls, bodybuilders, and distance runners. Data are based on 30,000 sequences per sample from the study subjects
