Michael (und alle), noch was zum Lesen dazu.

Er sieht auch Probleme mit der Zone 2 von Friel, die manchmal zu hoch ist (Hervorhebung von mir).

To guide my athletes, I will tell them that AeT typically lies near the top of Friel Heart Rate Zone 1 (“Friel Zn 1”). I’ve found that in nearly all triathletes, their AeT will be below this point. Indeed, for triathletes, their “weak sport” AeT will normally lie 10 bpm or more below the top of Friel Zn 1. This is important because, as coaches, we often specify Friel Zn 2 as the appropriate intensity zone for endurance training. In doing this we could inadvertently be giving our athletes tempo training in their endurance sessions.

Deshalb empfiehlt er eine subjektive Methode zur Bestimmung der aeroben Schwelle (AeT). Das Training soll dann sein im Bereich AeT +/- 5 Schläge .

My preferred evaluation method is to apply subjective perception. Start training at an easy pace and slowly increase the intensity of exercise. AeT is determined by noting the heart rate where you feel the first deepening of your breath.

Und dann wirds dude-like:

Don't over think this. You don't need to be sitting on an exact wattage or heart rate to benefit from your endurance training. The key thing is to be out there each day.

Na dann..
