Hydration Testing

Nutrition Works conducts Hydration testing at various locations throughout WA including Kings Park, Claisebrook Cove (Mardalup Park) and Burswood foreshore.

Bookings can be made via email and time and location arranged according to time of year and personal preference.

The Hydration testing provides us with information about personal fluid losses and sodium losses.

From the results we provide a suggested fluid intake/hr and electrolyte intake/hr.

We also review your current training nutrition (eg: Current sports drink, types of gels, approx. volume of fluid consumed, etc…) and provide nutrition strategies based on your results focusing on appropriate fluid volume, electrolyte and carbohydrate.

If training for a specific race eg: Marathon or Ironman 70.3 we provide a sample plan based on the results too.
