[01:29] Physiological testing in swimming: which metrics are of interest?

[02:40] VO2max – Maximum aerobic performance. How to test VO2max without measuring it during the swim.

[07:40] VLamax – Maximum glycolytic performance. Why non-sprint measures tell you something about VLamax.

[12:00] Economy – energy cost vs speed. Why oxygen uptake is not a good marker for energy demand and how to tackle that. And how to know whether you should focus more on improving economy or on increasing VO2max or VLamax.

[19:00] Energy contribution – % aerobic vs % anaerobic. And how this tells you what you should focus on in training.

[20:20] Anaerobic threshold (or MLSS). The definition, why it does not occur at a specific lactate concentration per se (e.g. 4mmmol) and how the body behaves above and below threshold.

[25:50] Lactate kinetics. And how you can predict lactate values using this information.

[31:30] Testing protocols: how to measure those metrics?

Using 3 efforts & lactate values only

[36:50] What to do when you also want to add swimming economy.

[37:50] Adding body composition to the results.

[38:20] Follow up assessments: testing smart!

Monitoring the athlete over time. How to easily see if your athlete is adapting, using 1 single effort only.

[44:35] Turning data into information: interpretation of results

[45:00] VO2max

[46:00] VLamax

[47:00] Interplay VO2max & VLamax

[49:30] Economy

[51:45] Understanding energy demand & supply

[53:50] Application to training: game changer TZB

Comparing 2 athletes and the training effect
