Estimativa da hidratação de corredores de rua em competições de 10 km

Abstract

Introduction: Adequate hydration during physical exercise is essential for maintaining sports performance and thermoregulation, especially in aerobic modalities such as road running. However, excessive fluid losses or inadequate fluid replacement strategies may impair physical performance and increase the risk of exercise-related complications. Objective: To analyze the hydration status and fluid replacement habits of road runners during official 10-km races held in the metropolitan region of Goiânia, Brazil. Methods: This is a cross-sectional observational study with a quantitative and descriptive design, conducted with 27 road runners participating in two official 10-km races. Hydration status was assessed through body mass variation before and after the races, in addition to self-reported fluid intake during the event. Results: The mean dehydration observed was 0.98 ± 0.76% of body mass, with 88.9% of participants presenting body mass losses below 2%, remaining euhydrated. Mean fluid intake during the races was 279.63 ± 176.10 mL. No significant associations were observed between dehydration percentage, level of running experience, and presence of a coach. Conclusion: The runners evaluated presented low levels of dehydration during the analyzed races, suggesting adequate maintenance of hydration status. The short duration of the races and the availability of hydration stations may have contributed to the observed results.
