My experience:

Corresponding cycling zones are lower, swimming zones probably higher. Arhab already explained it by the degree of muscle movement.

Example AeT for me:
Mountaineering w/o poles 147 (just legs)
Mountaineering w/ poles 155 (legs and arms)
Running – 165 (whole body movement and core)
Rollerskiing – 170 (whole body)

What does your nose breathing say while cycling?

What does this mean in terms of ADS? I’m NOT aerobically deficient when running, but am I when cycling? Or does the 10% rule not apply for cycling???

Yes, you could be. Mechanics play a huge part. If you’re less well-trained in cycling, then you’ll be less efficient. If you’re less efficient, then you could easily have a bigger gap between cycling thresholds.

And, lastly, when running my measured HRmax is 205, while when cycling I can’t get it higher than 192.

Unless they’ve been tested in a lab, I wouldn’t refer to any heart rate as “max”.

Again, makes sense for the reasons already mentioned. Cycling uses less muscle mass, especially if less trained, so HRs for a certain intensity will be lower.

I can also nose-breath up to high in the 160’s. Even when I’m doing above threshold intervals and my muscles are screaming I can easily breath. I guess my muscle power is not on par with my cardiovascular capacity.

ALso during such an interval I think I’m dying and don’t want to do another one, but I recover within 2 minutes to a zone 1 HR, and I feel “fresh” again for the next interval.

SO I have developed a string aerobic base I guess, but now need to work on muscle power/anaerobic capacity….
