Over 1300 tests and counting.

Knowing your numbers for sodium concentration in your sweat and the amount of sweat you lose helps you hydrate properly. We’ve tested over 1300 people so far and are here to help you understand your own requirements.

One hour at competition effort.

The test consists of a one-hour workout on a stationary bike or treadmill. Apart from learning the concentration of sodium in your sweat, the reason for the one-hour test is to help identify the volume of sweat you lose, which will give you a better understanding of your sweat rate per hour. Ideally you would perform the test at an intensity as close to competition effort as possible. You can use heart rate, average pace, or wattage to measure intensity.

Why not 30 minutes.

We all start to sweat at different times and from different areas of our body so the amount of sweat you lose in 30 minutes may not be a true indication of how much sweat you would lose in an hour after a suitable warm up. The amount you sweat, what areas of the body you sweat from, and at what point you start to sweat has nothing to do with how fit you are or how heat acclimated you are. It’s simply your unique physiological makeup. Testing for one hour after a suitable warm up will help you understand your own unique numbers more accurately.

What you learn.

You will learn the volume of sweat you lose based on the intensity and the environmental conditions the test is performed in. Remembering your sweat rate will change as intensity and the environmental conditions change.

You will learn the concentration of sodium that is present in your sweat. This is recorded in milligrams per one litre of sweat. The sodium concentration of your sweat is unique to you and it doesn’t change, which is why you only need to do the sodium test once. When you combine your sweat rate with the sodium concentration of your sweat you can calculate the accumulative amount of sodium you lose per hour.

Put simply, as sweat rate increases in warmer conditions so does the amount of sodium you lose. Conversely when temperatures are cooler sweat rates are lower and so is the amount of sodium you lose. Therefore the amount you hydrate is dictated by your unique physiological makeup and the conditions you are experiencing at the time.

If you are using a Heart Rate device you can also learn how many calories you are expending based on the intensity you do the test at. Knowing your calorie expenditure per hour also provides you with the information you need to plan your calorie intake accordingly.

Your sweat rate, sodium concentration in sweat, and calorie expenditure is important information to have when planning a nutrition strategy. The longer time goes on competing, the more important these numbers become.
