Sweat Profiling for Cyclists and Athletes

How much do you need to drink in training and competition to stay hydrated?  How much sodium do you need to replace during and after exercise?


Why measure fluid losses?


Did you know that as little as a 2% drop in bodyweight due to sweat loss can result in:

  • increased levels of fatigue

  • decrease in performance 

  • decrease in power

  • decrease in reaction time, 

  • poor decision making

  • impaired cognitive function


Why measure sodium?

When we sweat we loose fluid and electrolytes and the primary electrolyte in sweat is sodium.  It is used carry electrical signals around the body to ensure proper nerve and muscle function and is responsible for water regulation in the body and aids in the absorption of water. The amount of sodium in sweat varies greatly between individuals. 

What is involved?


The sweat test begins with checking hydration status by analysing a urine sample. Fluid consumed during the test is measured to help determine fluid losses along with body weight pre and post exercise. The sodium content of sweat is measured via collection on special patches placed on the skin during the test. Patches are sent to a specialist lab in Melbourne, The Sweat Lab, for analysis.


Your personalised sweat profile


All of these measures are collated into a personalised hydration and electrolyte strategy with the goal of increasing performance, wellbeing and recovery.  Specific recommendations can be made for suitable products to use during and post exercise.
