SODIUM CONCENTRATION

What to do with your value

What does the value say and why should I know my sodium loss?

The spectrum of salt concentrations in the sweat of athletes measured so far ranges from 200-2300mg/l sweat - depending on intensity, individual paramaters, outdoor temperature, ...


If you lose more than 3500mg of sodium, symptoms of weakness and muscle cramps will appear. If you lose more than 5000mg, you may experience increased tendency to collapse, severe muscle cramps, dizziness and vomiting. Fortunately, you can counteract these symptoms relatively easily if you continuously supply yourself with sodium during intense effort.

 

As example: If your value is 790 mg/l you should - simply said - intake 790 mg sodium with 1 liter fluid or substitute 790 mg with bars or gels after losing 1 liter of sweat.

 
How can I integrate my sodium value into the app?

If you already have registered an account in our mobile app you only have to start the app and look at the dashboard. There you should find the tile 'SWEAT PACK' with a corresponding button 'Add SWEAT PACK'. After pushing on the button a new view appears where you can enter your 'serial sumber' which begins with the letters 'SP-'. When you have entered your serial number you have to push again on the “Add SWEAT PACK” button. Now you should see your Sodium concentration in the Dashboard of the app. If you haven't download our app, you can do it here.

What is the sweat pack?

With our sweat diagnostic kit, the Sweat Pack, you can easily analyze your sweat during your workout.

The composition of sweat varies from athlete to athlete. Sweat consists of 99% water and is primarily used for thermoregulation. Sodium is dissolved in it and is the most important electrolyte in the context of substitution.

The sodium content varies between 200mg and 2300mg per liter of sweat.

The basis of the Sweat Pack is a scientifically validated method which was designed for sweat analysis in the field and further developed by us.

How does the sweat diagnostic kit work?

In your sweat kit you can find a flyer with further instructions about wich steps you should pass to get your personal sweat analysis. For more details you can take a look in our 'How to use the sweat kit'.

What is your individual sweat profile?

If there is a major, unbalanced sweat loss, your blood volume decreases. The blood becomes more viscous and the oxygen transport to your muscles is reduced. Already from a sweat loss of more than 2% of your body weight, your body therefore limits its performance.

Depending on the type of sport, indoor or outdoor and under very warm conditions, your sweat flow can be up to 4 liters per hour.

We will take all the parameters into account to get the most individual support as possible. In our App you can figure out your individual sweat profile.

How can the App help me?

The app supports you in creating your individual sweat profile. Based on that we will create your fueling strategy.

Considering your individual energy demand, your race course and your sodium loss in correlation, we will be able to provide you a 100% individual pacing strategy.

What is the carbohydrate combustion?

The amount of energy you have stored in form of carbohydrates in muscle and liver glycogen is biologically limited. 

Your carbohydrate combustion is the connection between your recommended carbohydrate intake and your power output, depending on your training level, your current threshold, VO2max and much more.

We can show you how much carbohydrates you'll need aligned to your current power output.

For your race day we will create a 100% customized fueling and pacing strategy based on your own and individual data.

You can get more information about the procedure in our Carbohydrate Test section.
