About this trial
This study aims to learn about relative energy deficiency in male and female rowers at the end of the direct sport preparation phase of the annual training cycle. The main questions:
\- How will energy intake influence leptin, cortisol levels, mood, gut discomfort, and permeability? The observational study involves male and female rowers from the Polish rowing team.
Participants will perform 2000 meter ergometer test and 6000 ergometer test in annual training cycle. Researchers will compare outcomes from both tests.

Trial outcomes
Primary outcomes
1
-FABP (intestinal fatty acid binding protein)to measure epithelial wall injury
