Abstract: Background: Electrolyte replacement is commonly used by athletes.There are multiple commercially available electrolyte drinks.However, it is not known whether the consumption of electrolyte drinks before exercises actually replaces electrolytes or causes their excretion through urine.We assessed whether the consumption of electrolyte drinks before regular exercise and or intensive sweating replaces electrolytes, or they are excreted via urine.Methods: Electrolyte concentrations in drinks and urine were measured by multimeter and home-made conductance sensors.Urinalysis was performed using 10-parameters commercial urine test strips.Experiments were conducted with water (control) and Prime at baseline and hourly after up to 4 hours in 3 different settings: "no exercise", "exercise only" and "exercise and sauna".Urine samples were collected before and at different time points after consumption of 500mL water or Prime.Results: Among electrolyte drinks, PRIME had the highest electrolytes content.Thus, it was selected for further experiments.In all settings, the consumption of water caused a decrease in urine electrolytes, specific gravity and pH.Those changes were most prominent after exercise and sauna.PRIME lessened the drop-in urine electrolytes, specific gravity and maintained urine pH after exercise and sauna.In the "no exercise" setting, PRIME caused an increase in urine electrolytes due to excess excretion.With exercise and sauna water did not prevent a decrease in urine electrolytes, despite the significant drop in specific gravity.Urine pH became acidic.PRIME, however, maintained the urine electrolytes concentration and pH and prevented urine acidification.Conclusion: PRIME consumption before exercise/sauna replaces the body's electrolytes, prevents urine acidification, and does not negatively affect urinalysis.
