Key concepts and best practices in performance diagnostics and metabolic testing.
Heart rate zones are guesses. VO2 testing shows what's actually happening inside your body. Here's why it matters for every endurance athlete.
Some athletes burn fat efficiently at high intensities. Others depend on carbs from the start. A metabolic test reveals which type you are — and how to train accordingly.
Finding the intensity where your body burns the most fat.
From fat burning to VO2max - training with metabolic precision.
Why power data is essential for accurate metabolic analysis.
The metabolic fingerprint that reveals your fuel mix.
The science behind long, slow distance training. Why 80% of your training should feel too easy - and how to find the right intensity.
Where to get a spiroergometry test, what it costs, how to prepare, and how to do it yourself with portable equipment.
Achilles tendon pain, chronic fatigue, stagnating performance - often caused by wrong training intensity.
The gold standard of cardiorespiratory fitness.
