| Abstract: | Context: Urine lactate may be a novel biomarker of lactate production capacity but its reliability has been unsatisfactory so far. Objective: To compare the reliability of urine lactate between controlled hydration and no hydration after maximal exercise. Material and methods: Athletes performed swimming exercise four times: two followed by consumption of 1?L of water and two followed by no water intake. Blood and urine lactate was measured. Results: The reliability of urine lactate was good and similar to that in blood only after controlled hydration. Blood and urine lactate were correlated under both hydration conditions. Discussion and conclusion: Controlled hydration after exercise provides satisfactory reliability of urine lactate. |
