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.

Interventions

Rowers will perform 2000m ergometer test. A 2,000-meter trial is a standard test used to assess performance in rowers.

MeasureTime frameDescription
-FABP (intestinal fatty acid binding protein)to measure epithelial wall injuryBlood 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 periodI-FABP concentration measured in blood \[ng/ml\] using commercially availableenzyme-linked immunosorbent assays
Leptin to measure long-term energy balanceBlood 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 periodLeptin concentration measured in blood \[ng/ml\] using commercially availableenzyme-linked immunosorbent assays
Cortisol to measure stressBlood 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 periodStress hormone concentration measured in blood \[ng/ml\] using commercially available enzyme-linked immunosorbent assays
sCD14 multifunctional lipopolysaccharide receptorBlood 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 periodsCD14 concentration measured in blood \[ug/ml\] using commercially available enzyme-linked immunosorbent assays
Claudin to measure tight junction leakageBlood 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 periodClaudin concentration measured in blood \[ng/ml\] using commercially available enzyme-linked immunosorbent assays
