What is a common indicator of dehydration in athletes?

Dark yellow urine is a common indicator of dehydration in athletes because it typically signifies that the body is conserving water. When an athlete is well-hydrated, urine tends to be pale and clear, reflecting adequate fluid intake. Conversely, when dehydration occurs, the kidneys conserve more water in an effort to maintain hydration, resulting in concentrated urine, which appears darker in color. Monitoring urine color can be a practical and effective self-assessment tool for athletes as they regulate their hydration status during training and competition. This understanding emphasizes the importance of maintaining proper hydration to support performance and overall health.
