One of the greatest mysteries for any endurance athlete is the quantity of sodium and fluid they should consume each hour during training and competition.  Are you consuming too much? Too little? Let the eNRG Performance Sport Dietitian Team help solve this mystery for you!  With a simple sweat sodium concentration test combined with meticulous sweat rate testing, our Sport Dietitians will accurately measure your normal sweat sodium concentration and provide a customized sodium and hydration plan for you to use during training and competition.  The best part is that this test does not require you getting on a treadmill or bike.  Plan for a 45 minute appointment at any time of the day and don't worry about bringing exercise clothes!

Your appointment will include a 45 minute meeting with an eNRG Performance Sport Dietitian, sweat sodium concentration testing, and a full interpretation and hourly sodium and fluid recommendations.

Information About the Test

  • This is a non-exercise test.
  • The purpose of this test is to determine the concentration of sodium in your sweat, extrapolated per liter of sweat volume. This tells us how “salty” your sweat is.
  • To collect the sweat sample, we use your inner forearm to activate the sweat glands via a light electrical current and a non-toxic chemical gel.  A medical grade analyzer will measure your sweat sodium concentration immediately, so you have results right away.
  • Because your sweat sodium concentration is largely genetically determined, this is a one-time test. You do not need to repeat this testing.


Test Preparation

  • Try to avoid exercise in the 2 hours prior to your scheduled appointment.
  • Arrive at your appointment adequately hydrated.
  • There is no need to fast for this appointment.
  • If you have a large amount of hair on your inner forearms, we may ask you to shave a portion of your inner forearm for the application of the equipment.
  • If you have current sweat rate data to indicate your typical fluid losses, please bring your information to the appointment.  Click HERE for the instructions on how to do your own sweat rate testing.
