AI-Summary

What this Trial Is About

This trial evaluates the effects a moderate-to-vigorous exercise intervention has on the bacterial make-up of the gastrointestinal tract (gut microbiota) in survivors of stage II-III colorectal cancer (CRC). Data shows that the gut microbiota composition and function may be drivers of CRC. High levels of exercise are associated with improved CRC prognosis and survival. While data suggests that exercise has the potential to influence gut microbiota composition and function, it is not known whether these effects contribute to improved CRC prognosis. This clinical trial evaluates the effects an exercise intervention has on gut microbiota and how these effects relate to CRC progression and patient-reported outcomes.
