Effect of Exhaustive Swimming on the Kidney Urinary Concentration Function
This paper aims to study the effect of exhaustive swimming on the kidney urinary concentration function. After 6 weeks of exhaustive swim training, plasma osmolality (Posm), urinary osmolality (Uosm), serum Na+, K+ concentration, the expression of kidney aquaporin 2 (AQP2), and its mRNA are all observed. The results show that 6 weeks of exhaustive swim training will be harmful to the kidney urinary concentration and can deduce the body dehydration. The decrease in the expression of AQP2mRNA significantly plays an important role in the change in the kidney urinary concentration function. The decrease in renal reabsorption of water maybe the main cause of fatigue resulted from the extreme load.
