Hydration

HOW IT WORKS

The assessment is completed at rest, so there is no need to exercise or arrive having already worked up a sweat. A safe, low-level electrical current stimulates the sweat glands on a small area of your forearm. The resulting sweat sample is collected and analysed to establish your individual sweat sodium concentration. The process is simple, painless and does not involve needles. While the test is taking place, we discuss your sport, training, competition goals, current hydration practices and any problems you have experienced in longer sessions or challenging conditions.

YOUR RESULTS

Following the test, we explain your result and develop a personalised hydration strategy. You will receive:

This assessment measures the concentration of sodium within your sweat; it does not directly measure how much fluid you lose per hour. Your overall hydration requirements will depend on both your sodium concentration and your individual sweat rate. Cramp, headaches and reduced performance can have multiple causes. The results will therefore be interpreted within the context of your wider training, fuelling and competition demands.
