Answer: hard. Looking back at a session I once did for a laboratory study. Incremental exercise test: after 2 minutes at 300, 350, 375, and 400 W, lasted 30 seconds at 425 W with a VO2max of 5.35 L/min, hitting a max HR of 174 BPM. Follow-up supramaximal effort #1: rode for 2 minutes at 400 W and…

[image] fet_och_gammal: I did that for 60 minutes during the State Champs RR-and did 180 for 90 mins…never thought my LTHR was that high Be careful using race data to inform HR targets. Adrenaline has a big input. A few examples of mine from past races: 6 hours at 89% of max HR 1.5 hrs at 9…

Despite being so easy to measure, I still find HR surprisingly hard to interpret… HRmax varies from one day to another. I’d find it impossible to prescribe my intervals as a certain %HRmax just because I don’t know what “HRmax” is at a given point in time.

Or not. But thanks for believing you’re the only person whose ever ridden a bike hard enough.

The two VO2max tests I’ve done have been for clinical research trials. Both times it was using a recumbent trainer bike, which I’d never used before and didn’t get on with. Felt like I was using completely different muscle groups. On that basis I reckon I under-tested - that’s my excuse anyway. …

Who said anything about prescribing intervals based on HR?

Well I understood your post as implying that one should get “near” HRmax to effectively train VO2max (making the additional assumption that one should be “near” VO2max for VO2max intervals to be effective). If this is the case then it is only natural to target a certain %HRmax (at least as a necessa…

Probably not the correct thread, but this is short enough to digest for me… I was doing my VO2 max sessions last season based on RPE and stopped looking at power during the interval. I was focused on high cadence and making sure HR stayed elevated. Still felt like death during and after. I know …

Pedaling abnormally fast makes you inefficient, and so 1) reduces the power you will generate at/near VO2max, but 2) also elevates your HR even at the same VO2. So, it’s hard to say how close you were to VO2max based on your HR (or RPE). Your power, though, will always tell you the “floor”, no matte…

Would definitely not get you close to your VO2max. You end up with a lot less perfusion of the muscles because gravity isn’t helping, so legs get starved of oxygen. Researchers use it to investigate pathologies (diabetes, aging etc) where there’s a drop in VO2max or slowed kinetics, to see if it’s f…
