Which of the following is a common sign of dehydration in athletes?

Slowed reaction time is indeed a common sign of dehydration in athletes. When the body is dehydrated, it affects cognitive and physical performance, leading to impaired reaction times. Dehydration can cause changes in electrolyte balance and blood volume, which can result in decreased mental focus, increased fatigue, and slower response to stimuli. This impairment can be particularly critical in sports requiring quick decision-making and agility.

In contrast, increased appetite is typically not a sign of dehydration; rather, some individuals may experience decreased appetite when dehydrated. Clear urine output is an indicator of good hydration, as well-hydrated individuals typically have light-colored urine. Improved coordination, like clear urine, suggests proper hydration levels and physiological functioning. Understanding these signs helps in monitoring an athlete’s hydration status and enhancing overall performance.
