Sweat sodium and hydration testing measures how much you sweat, how much sodium you lose, and how your hydration status changes during exercise. Your results are combined to create a personalised hydration strategy you can actually use during training, racing, or work in the heat.
Your 60-minute appointment includes exercise-based sweat sodium testing, sweat rate measurement, pre- and post-exercise hydration testing, and a detailed report with practical fluid and sodium recommendations.
Testing and interpretation are performed by a Clinical Exercise Physiologist with 19 years of experience.
Everyone loses water and sodium when they sweat, but the amount can vary considerably from person to person.
Sweat sodium testing measures the concentration of sodium in your sweat during exercise. Knowing that number is useful, but we also need to know how much you’re sweating.
During your appointment, we measure your sweat rate using pre- and post-exercise body weight, while accounting for fluid intake and exercise duration. Combining your sweat sodium concentration with your sweat rate gives us a much more useful picture of your estimated fluid and sodium losses during exercise.
We also assess your hydration status before and after exercise using saliva testing with the MX3 Hydration Testing System.
Together, these measurements help us build a hydration strategy based on your physiology rather than relying on generic recommendations.
Hydration needs can vary considerably between athletes, and drinking more water isn’t always the answer.
Your results can help you:
Testing can be particularly useful if you regularly finish runs with salt residue on your skin or clothing, sweat heavily, struggle with your hydration strategy, or are preparing for longer events or hot conditions.
Testing is performed using the MX3 Sweat Patch and MX3 LAB Pro during exercise.
Before you begin, we’ll assess your baseline hydration status with a quick saliva sample and record your pre-exercise body weight.
You’ll then exercise at a moderate intensity on the treadmill or bike while wearing a small sweat patch. The patch collects sweat during the session so we can analyse your sweat sodium concentration.
After exercise, we’ll repeat your hydration assessment and body weight measurement. Your fluid intake during the session is also recorded so we can calculate your sweat rate.
We’ll then put the results together to estimate your fluid and sodium losses and discuss how to apply them to your training, racing, or work environment.
The test is non-invasive and exercise-based, so your sweat sample is collected while you’re actually moving.
