Reviewer's report:
This paper deals with the effects of moderate aerobic and resistance training with regards to body  
composition  parameters  and  inflammatory  bowel  disease.  A  further  detailed  study  on  the  gut  
microbiome profile of the participants is added to reinforce the safety of moderate exercise in intestinal  
disorders patients.
Please,  consider  including  this  paper  reviewing  the  several  mechanisms  of  exercise  in  the  
hepatobiliary-gut axis, either in the background of the manuscript or : 10.1111/eci.12958. 
The n. of patients and (particularly) controls is rather small.
