Maximum oxygen uptake is the single most important measure of endurance performance - and one of the strongest predictors of life expectancy overall. PGC-1alpha controls the formation of new mitochondria, VEGFA the formation of new blood vessels in muscle, ACE vascular regulation, and ADRB2 the response to adrenaline.
Why this analysis matters
People respond very differently to the same endurance training - the range goes from barely measurable improvement to an increase of over 40 percent. The analysis shows where you need to focus if your body responds more slowly.
What the variants mean
Certain variants are associated in studies with a stronger training adaptation, others with a weaker one. Those who respond less strongly need more volume or more targeted intensity control to achieve the same results.
What you can do
With lower responsiveness, high-intensity intervals often work better than basic endurance training alone because they provide a stronger stimulus for mitochondrial formation. With good responsiveness, a high proportion of low-intensity endurance sessions is usually enough.
Frequently asked questions
Can I have my VO2max measured?
Yes, through spiroergometry or approximately through field tests. Genetic analysis shows your predisposition; the test shows your actual level.
Am I untalented if I have an unfavorable variant?
No. Fitness level has a much greater influence on VO2max than genetic predisposition. It only determines how quickly you progress.
