Clinical Trial Summary

The study aimed to check the 2000m ergometer test on markers of gut permeability in the competitive phase of rowers. 18 members of the Polish rowing team took part in the study.

Description:

The phenomenon of epithelial wall leakage has been the subject of investigations within athletic domains such as running and cycling. Nevertheless, there exists an insufficiency of understanding regarding gut permeability in alternative disciplines, such as rowing, particularly following the completion of a standard competitive distance of 2000 meters. Hence, the principal objective of our study was to assess gut permeability after completing a 2000-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 2000-meter ergometer test. Blood samples were taken before the test, after exercise, and after 1-hour of restitution. Parameters, such as I-FABP, LPS, LBP, and zonulin, were determined using appropriate biochemical tests.

Type	Measure	Description	Time frame	Safety issue
Primary	I-FABP (intestinal fatty acid binding protein)to measure epithelial wall injury	I-FABP concentration measured in blood [ng/ml] using commercially available enzyme-linked immunosorbent assays	Blood samples was taken from the cubital vein at three-time points: before each stress test (after overnight fasting), one minute after the end of the test, and after a 1-hour recovery period
Primary	zonulin to measure tight junction leakage	zonulin concentration measured in blood [ng/ml] using commercially available enzyme-linked immunosorbent assays	Blood samples was taken from the cubital vein at three-time points: before each stress test (after overnight fasting), one minute after the end of the test, and after a 1-hour recovery period
Primary	LBP (lipopolysaccharide binding protein) to measure endotoxin	LBP concentration measured in blood [ug/ml] using commercially available enzyme-linked immunosorbent assays	Blood samples was taken from the cubital vein at three-time points: before each stress test (after overnight fasting), one minute after the end of the test, and after a 1-hour recovery period
Primary	LPS (lipopolysaccharide) to measure endotoxin	LPS concentration measured in blood [EU/Ll] using commercially available enzyme-linked immunosorbent assays	Blood samples was taken from the cubital vein at three-time points: before each stress test (after overnight fasting), one minute after the end of the test, and after a 1-hour recovery period
Primary	Lactic acid to measure fatigue after the race	Lactate concentration measured in capillary blood from earlobe [mmol/L] using a commercially available kit (Diaglobal, Berlin, Germany)	Blood samples was taken from earlobe at two-time points: before each stress test (after overnight fasting), one minute after the end of the test.
