- Lead Sponsor
- Poznan University of Physical Education
- Brief Summary
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.

- Primary Outcome Measures
Name Time Method Leptin to measure long-term energy balance Blood samples was taken from the cubital vein at three-time points: before each stress test (after overnight fasting) up to one hour after getting up, 1 minute after the test, and 3-hour recovery period Leptin concentration measured in blood \[ng/ml\] using commercially availableenzyme-linked immunosorbent assays
Claudin to measure tight junction leakage Blood samples was taken from the cubital vein at three-time points: before each stress test (after overnight fasting) up to one hour after getting up, 1 minute after the test, and 3-hour recovery period Claudin concentration measured in blood \[ng/ml\] using commercially available enzyme-linked immunosorbent assays
Cortisol to measure stress Blood samples was taken from the cubital vein at three-time points: before each stress test (after overnight fasting) up to one hour after getting up, 1 minute after the test, and 3-hour recovery period Stress hormone concentration measured in blood \[ng/ml\] using commercially available enzyme-linked immunosorbent assays
REST-Q sport day before the test Recovery-Stress questionnaire for Athletes
-FABP (intestinal fatty acid binding protein)to measure epithelial wall injury Blood samples was taken from the cubital vein at three-time points: before each stress test (after overnight fasting) up to one hour after getting up, 1 minute after the test, and 3-hour recovery period I-FABP concentration measured in blood \[ng/ml\] using commercially availableenzyme-linked immunosorbent assays
sCD14 multifunctional lipopolysaccharide receptor Blood samples was taken from the cubital vein at three-time points: before each stress test (after overnight fasting) up to one hour after getting up, 1 minute after the test, and 3-hour recovery period sCD14 concentration measured in blood \[ug/ml\] using commercially available enzyme-linked immunosorbent assays
