Details and patient eligibility

About

In recent years there has been a significant increase in the number of participants in high intensity and duration sports events. This type of physical exercise has been reported to lead to an apparently transitory deterioration in kidney function. The injury mechanisms involved in this process have not been fully studied, but several have been proposed as potential causes, such as tissue ischemia, disruption of the permeability of the glomerular basement membrane, damage to the ultra-structure of skeletal muscle, structural involvement of the renal parenchyma, exercise-associated hyperthermia or insufficient hydration during exercise.

Urinary biomarkers, which are a more precise tool than serum creatinine when it comes to detecting subclinical kidney damage, may be key to elucidate the characteristics of exercise-related kidney injury.

The aim of this study is to carry out an integrative analysis of the development of exercise-associated subclinical acute kidney injury.
