Table 1.

Enterotypes by group. Enterotypes split by experimental group. Percentage of each enterotype in each group is given between parentheses. Significant p-values in post-hoc test are designated with star notation: <0.001: ****, <0.01: **, <0.05: *.

Enterotype	1	2	3
CONTROL	12(26)	7(15)***	27(59)***
MR	4(29)	8(57)*	2(14)*
CSS	4(36)	6(55)	1(9)*

Enterotypes’ drivers: 1- Ruminococcaceae family and Barnesiella genus, 2 – Prevotella, 3-Bacteroides

MR – marathon runners, CCS – cross-country skiers
