Dehydration is one of the most common nutritional factors that can affect athletic performance.  Cramping, fainting, heat strokes, and electrolyte imbalances are common side effects of dehydration.

General guidelines

Athletes should drink generous amounts of water the day before training or participating in an event.  This helps decrease the risk of becoming dehydrated during training the next day.  Drinking 13-20 oz of water 2-3 hours before exercise will also help decrease the risk of becoming dehydrated during training. A larger athlete may need to drink more.  Athletes should drink at least 6-12 oz of fluid every 15-20 minutes during exercise.

The first nutritional priority after exercise is to replace any fluid lost during exercise. In general, the best way to determine how much to drink is to:

  • Weigh yourself before and after exercise
  • Replace fluid losses by drinking 20-24 fl oz water for every 1 lb of weight lost
  • Sports drinks may be helpful if exercise lasts longer than 1 hour. Sports drinks are also helpful when no food is consumed after exercise. 

Are you tired of the regular old sports drink?  Here is a recipe for a homemade sports drink.  

  • ¼ cup sugar
  • ¼ teaspoon salt
  • ¼ cup hot water
  • ¼ cup orange juice (not from concentrate)
  • 2 tablespoons lemon juice
  • 3 ½ cups cold water

In the bottom of a pitcher, dissolve the sugar and salt in the hot water. Add the juice and remaining water.  Chill and enjoy!  Other flavors such as cranberry and lemonade can be used.
