Every athlete sweats differently. One person may lose around 200 mg of sodium per litre of sweat, while another may have a concentration of 1,500 mg/L or even more. These differences determine whether standard hydration advice is sufficient.

Without precise data, electrolyte replacement is always only an estimate. During prolonged exercise, insufficient sodium intake may contribute to fatigue, reduced performance and poorer heat tolerance.

A sweat analysis shows how much sodium you actually lose. Based on the result, you will receive a personalised hydration plan covering fluid intake, drinking timing and electrolyte dosing for different types of exercise.

The complete assessment takes approximately 60 minutes, is non-invasive and consists of two main parts.

A sweat analysis helps you better understand how your body cools itself during exercise and how much fluid and sodium you need to replace continuously.

Sweat analysis has broad value and offers something different to every athlete. Elite athletes can use it to fine-tune details that matter at the limits of performance. Competitive and amateur athletes can use it to better manage long training sessions, races and hot conditions.

It is also suitable for recreational runners, cyclists, triathletes and anyone who exercises for extended periods and wants hydration to be as individualised as their training plan or diet.

Sweat analysis is currently available only in Prague. Testing locations in Brno and Olomouc are being prepared, and we will announce their launch as soon as specific appointments can be booked.
