Abstract
Purpose
Endurance exercise and hyperthermia are associated with compromised intestinal permeability and endotoxaemia. The presence of intestinal fatty acid-binding protein (I-FABP) in the systemic circulation suggests intestinal wall damage, but this marker has not previously been used to investigate intestinal integrity after marathon running.
Methods
Twenty-four runners were recruited as controls prior to completing a standard marathon and had sequential I-FABP measurements before and on completion of the marathon, then at four and 24 h later. Eight runners incapacitated with exercise-associated collapse (EAC) with hyperthermia had I-FABP measured at the time of collapse and 1 hour later.
Results
I-FABP was increased immediately on completing the marathon (T0; 2593 ± 1373 ng·l−1) compared with baseline (1129 ± 493 ng·l−1; p
Description
The study evaluates temperature measurement devices for athletes exercising outdoors in hot conditions.
