Inflamation, Gut Leakage, Iron Status After 6000m Ergometer Test in Elite Rowers.

Influance of 6000m Ergometer Test on Inflammatory, Permeability Markers and Iron Status.

The influence of a 6000m ergometer test on the markers of gut injury, endotoxemia, iron status, stress and inflammation in elite rowers.

The principal objective of our study was to assess gut permeability after completing a 6000-meter rowing test. The study was performed at the beginning of a competitive training phase. Eighteen elite Polish Rowing Team rowers participated in the study after applying the inclusion/exclusion criteria. The participants performed a 6000-meter ergometer test. Blood samples were taken before the test, after exercise, and after 1 hour of restitution. Parameters, such as I-FABP (intestinal fatty acid binding protein), LPS (lipopolysaccharide), LBP (lipopolysaccharide binding protein), claudin3, ferritin, transferrin, hepcidin, IL-6 (Interleukin-6), HO-1 (Heme Oxygenase 1), and ACSL4 (Long-chain-fatty-acid-CoA ligase 4 ) were determined using appropriate biochemical tests.

Inclusion Criteria:

• minimum five years of training,
• five training sessions per week minimum,
• total training time minimum of 240 minutes,
• membership in the Polish Rowing Team,
• finishing the 6000-meter ergometer test.

Exclusion Criteria:

• antibiotic therapy within the last three months,
• probiotics and prebiotics within the last three months,
• dietary regime,
• gastrointestinal diseases.
