| الوصف: | El estrés oxidativo se ha estudiado ampliamente en asociación con los deportes de ultrarresistencia sin que haya un consenso sobre las repercusiones del mismo. El objetivo de este estudio fue dilucidar el impacto de una carrera de ultratrail sobre el estado oxidativo plasmático de 32 corredores y su recuperación postcarrera, con especial atención al efecto del sexo y la edad. Se observó un aumento del daño oxidativo en lípidos y proteínas (MDA y CG) tras la carrera y 48 horas después. Asimismo, se produjo un aumento de la actividad GR en meta que se mantiene durante las 24 horas posteriores. Además, los valores basales del estado oxidativo plasmático de los corredores se relacionan con el grado de daño muscular y fatiga tras la ultratrail y su posterior recuperación. Por último, tanto el género como la edad de los participantes son factores que influyen en los resultados obtenidos. |
| Description (Translated): | Oxidative stress has been widely studied in association to ultra-endurance sports. Althoughit is clearly demonstrated the increase in reactive oxygen species and free radicals after these extreme endurance exercises, the effects on the antioxidant defenses and the oxidative damage to macromolecules, remain to be fully clarified. Therefore, the aim of this study was to elucidate the impact of an Ultra Trail race on the plasma markers of oxidative stress of 32 runners and their post-race recovery, with especial focused on sex and age effect. For this purpose, the antioxidant enzymes glutathione peroxidase (GPx) and glutathione reductase (GR) activity, as well as the lipid peroxidation product malondialdehyde (MDA) and the carbonyl groups (CG) content were measured before the race, in the finish line and 24 and 48 h after the race. We have reported an increase of the oxidative damage to lipids and proteins (MDA and CG) after the race and 48 h later. Moreover, there was an increase of the GR activity after the race. No changes were observed in runners’ plasma GPx activity throughout the study. Finally, we have observed sex and age differences regarding damage to macromolecules, but no differences were found regarding the antioxidant enzymes measured. Our results suggest that several basal plasma markers of oxidative stress might be related to the extent of muscle damage after an ultraendurance race and might affect the muscle strength evolution.
