borderline significancep = 0.05
Envfit analysis showed that only body mass showed borderline significance explaining the total variation in gut microbiota composition ( p = 0.05), whereas the improvement in VO 2 max (i.e., effect size of the exercise training intervention) and the other potential explanatory variables (i.e., sex, age, M‐value, BMI, VO 2 max, VAT volume, and dietary intake measures) did not explain significantly the differences in microbial composition of the participants before and after the intervention.
