The epithelial wall leakage has been extensively studied in sports disciplines like running and cycling. However, little is known about gut permeability other disciplines, rowing, especially after the regular competition performance distance of 2000 m. Therefore, our study aimed to check 2000-meter rowing test annual training cycle. phenomenon subject investigations within athletic domains such as Nevertheless, there exists an insufficiency understanding regarding alternative particularly following completion a standard competitive Hence, principal objective was assess test. performed at beginning phase. Eighteen elite rowers Polish Rowing Team participated applying inclusion/exclusion criteria. participants ergometer Blood samples were taken before test, exercise, 1-hour restitution. Parameters, I-FABP, LPS, LBP, zonulin, determined using appropriate biochemical tests. There no changes between pre- post-exercise values zonulin. I-FABP changed from 6,49 ± 2,15 8,3 2,71 (ng/ml) during recovery period, LBP decreased 2,73 0,77 2,035 0,53 (µg/ml) simultaneously. Other parameters have not changed. results this showed that intense physical effort period sufficient negatively affect integrity rowers.

This case-series describes a four-phase management approach implementing gastrointestinal assessment during exercise (GastroAxEx) to develop therapeutic interventions for athletes affected by exercise-associated symptoms (Ex-GIS). Recreational elite-level who experienced recurrent severe Ex-GIS (n = 9) and controls 2) (without Ex-GIS) volunteered participate in the case series. The four-phased involved clinical (Phase 1), standardized laboratory GastroAxEx where physiological strain GIS data were collected 2), individualized intervention strategies based on Phase 2 outcomes that specifically included implementation of 48-hr high carbohydrate low FODMAP diet 3), monitoring adjustment 4). majority 6/9) consumed <400 ml/hr fluid ad libitum, resulting 2%-4% body mass loss, <40 g/hr exogenous 8/9), GastroAxEx.

In the present study, we aimed to determine effect of moderate ambient heat stress on exercise-provoked patterns "leaky gut" biomarkers and markers in well-trained athletes. Eleven triathletes performed a strenuous 1-h treadmill run, both under normal conditions (N, 18-21°C) as well environmental (H, 28-30°C). Core body temperature (Tc), heart rate (HR), rating perceived exertion (RPE) significantly increased conditions, with higher values during after H run. We observed significant main acute exercise circulating leukocyte numbers, release cell-free human DNA (cfDNA) but not bacterial (bacDNA), plasma levels intestinal fatty-acid binding protein (I-FABP), lipopolysaccharide-binding (LBP), endotoxin (LPS), D-lactate. Exercising accelerated mobilization neutrophils lymphocytes, affected cfDNA, D-lactate, I-FABP, creatinine, blood potassium levels. Multiple correlation analysis revealed association between Tc, max cfDNA (r = 0.583, p 0.012) I-FABP 0.554, 0.026). Our data indicate that exercising may only affect paracellular also transcellular permeability.
