Background:
Prolonged exercise has been shown to result in an acute depression in endothelial function. However, little is known about the effect of this type of exercise in non-ekite runners.Objective:
To determine the impact of prolonged strenuous exercise on endothelial function in non-elite runners.Methods:
Nine males participating as recreatuional runners (age 49,5 + ou -5.1y) at the Santiago of Cali Half-marathon (21.097m) were studied. Endothelium dependent femoral artery flow-mediated dilatation (FA-FMD) was evaluated one day before the race and at 1h, 24h, 48h, and 6 days after finishing the half-marathon.Results:
A decrease on FA-FMD was observed at 1h after Half-marathon, followed by a non-significant recovery trend starting at 24h up to 6 days after the race. Increase in the posthyperemic diameter of the femoral artery was observed at 1h after race ending, with a trend to baseline values in subsequent measures.Conclusion:
Femoral artery diameter increased after prolonged running could explain the reduction of FAFMD. More studies with larger sample size are needed to determine the effects of prolonged running on femoral artery endothelial function.
