Max heart rate: is it bad to train in Zone 5 for 30 mins?
First every HR monitor will read your HR differently. To get an actual reading you will need to do a Vo2Max test at a Doctor.
2nd You are listing quite a large range for 30 minutes. There is a ...

Why is it impossible or nearly impossible to burn high levels of fat near VO2 max intensity?
The reason why it's hard to burn fat during high intensity exercise is that it's a slow and inefficient process of getting energy to the muscles. Your body will switch to using glycogen aerobically ...

How quickly will my VO2 max fall off if I stop all exercise?
The negative effect on VO2max due to detraining varies a bit with different studies, with losses ranging from 4-14% when training is stopped for less than 4 weeks [1-8]. Obviously, the longer the ...

Can you calculate % of V02 max at which you're working using pulse ox readings?
While it's an interesting question, it would be a very short lived time anyway.
VO2 max is the maximum oxygen your body can use at a given (usually fairly intense) activity level. If you exceed this ...

Why am I unable to run as fast as I should be able to, based on my VO2max
VO2max is the amount of oxygen which your cells are able to convert into CO2. It doesn't say anything about the anaerobic threshold, for that you need to do a Conconi test (there are many variants of ...

Why am I unable to run as fast as I should be able to, based on my VO2max
VO2 max is the amount of oxygen available for energy burn and is associated with runs that are shorter than 5-8 minutes total. Anything longer than this your body must deal with lactate acid buildup ...

Running, high HR, VO2max decreases overtime
VO2max is not super important for 10k. It's correlated with performance, but it's not a good predictor.

Why do elite cyclists seem to have higher VO2 max tham elite marathon runners?
I'm not positive about the premise here. There are certainly cases of runners having cyclist like VO2 levels.
Also, cyclists are way more testing conscious. The fact of the matter is elite cycling ...

How can fitness trackers estimate VO2 max without knowing how hard the exercise is?
No, the fitness tracker cannot tell that exercise has changed. This will result in a skewed value.

What exactly do fitness guides mean when they give a relative V̇O₂max?
Yes, V̇O₂ is “the weight-normalized volume rate of oxygen that is consumed during training,” expressed in ml/min/kg, but more fundamentally, it is a metric for the time-rate of energy production. Thus,...

If I'm training only for 5k, can I do mostly VO2 max training workouts?
V̇O₂max work rate can typically be held only for around 8 minutes or so, so you're not going to be racing at V̇O₂max pace. And while the pace will be "close", it's in the nature of endurance that ...
