Clinical Trial Summary

This study has as main objective to asses different genetic, biochemical and physiological biomarkers affecting performance and health status in ultraendurance runners according to individual's sex.


Description:

Ultraendurance races has been shown to impact on several health-related biomarkers, and therefore they may have detrimental effects on runners' health. In this study, we aim to analyze the impact of running a 107,6 km mountain race in ultraendurance runners splitting our sample by individual's sex.

To do this, baseline measurements of the runners have been collected through stress tests and biochemical analyses of blood and urine samples. Indeed, a saliva sample was collected to isolated a genomic DNA sample of each runner.

During the race anthropometrical, ventilatory and strength data was collected in three different moments and after crossing the finish line. Indeed, after completed the ultraendurance mountain race, blood and urine samples were taken at the finish line, as well as 24h and 48h post-race.
