Ultra-trail Participation Clinical Trial
Official title:
Evaluation of Biological Markers of Mesenteric Ischemia During an Ultra-trail
To assess the evolution of biological markers of mesenteric ischemia during ultratrail.
During physical exercise, increased sympathetic nervous system activity redistributes blood
flow from splanchnic organs to working muscles. With prolonged duration and / or intensity,
the splanchnic blood flow can be reduced by 80% or more. A severely reduced of splanchnic
blood flow can frequently cause gastrointestinal ischemia. This ischemia associated with
reduced vagal activity probably results in changes in motility and absorption.
High symptoms are reported in 40% of runners with reflux and heartburn in 15-20% of runners.
The low symptoms have an incidence of about 70% in the long runs type ultra-trail.
Biological markers such as I-FABP have been shown to be useful in the diagnosis of mesenteric
ischemia.
