Hydration Guidelines

Proper hydration is essential for athletic performance. Even 2% dehydration can significantly impact endurance and cognitive function.

  • Drink 400-600ml 2-3 hours before exercise
  • Drink 150-300ml every 15-20 minutes during exercise
  • In hot conditions, increase fluid intake by 25-50%
  • Monitor urine color - pale yellow indicates good hydration
