In this webinar we show how to measure the energy cost at a given swimming speed, using simple testing in the pool.

About the webinar

The energy cost at a given speed is decisive for the race performance in swimming.

The methods shown in this webinar are all based on peer reviewed scientific publications. We will show how a face worn VO2 Analyzer ( can be used for this testing at the pool.

You’ll learn how to assess energy cost in swimmers and triathletes, the effect of energy cost on overall performance. Another highlight of this webinar will be the application of the method to determine the energy cost or saving using different garments (swim suits, wetsuits, etc.).

The methods learned here apply for swimmers as well as for triathletes.
