High variability in sweat electrolyte losses 💦

Normative data is ok, but individualise where possible.

Interindividual variability in sweat electrolyte concentration in marathoners

Background

Electrolyte intake during exercise is essential to replace sweat induced electrolyte losses 🥵

There are various studies investigating the composition of sweat for electrolytes, but how variable are these electrolyte concentrations between individuals? 🧐
