Abstract

The hydroelectrolytic balance during the run is essential to a good performance and to the athlete’s health, especially for street runner fans who increase annually. Thereby, we aim to evaluate the hydration state by urine osmolarity in street runners. 62 volunteers (49M/13W, over 18 years) provided urine samples before(a) and after(b) the run. There was a decrease in urine osmolarity (UO) (mOsm/L) after the run (601+34a vs. 692+33b). Men exhibited higher UO than women (750+30b vs 476+88b) and a decrease after the run (631+36a), while women presented no alterations (487+90a). 30% of volunteers started the run with diluted urine (334+35, G1) and 70% in concentrated status (839+17, G2). The G1 group kept their UO in diluted state (267+32) even sweating during the run, while G2 group presented a decrease in UO, however it kept the concentrated status (738+27). Women and G1 start in a water loss state, which was maintained thought-out the run, leading to dehydration. Men and G2 started with high ADH levels, producing concentrated urine and, different than expected, they had urine dilution during the run. Considering this, we could identify an excess of hydration, before and during the exercise. This leads to the hydro-electrolytic disturbance, compromising the athlete performance.
