Hi ,
It looks like you're using an ad blocker.



The revenue generated from the adverts on the site is a critical part of our funding - and it's because of these ads that I can offer the site for free. But using the site for free AND blocking the ads doesn't feel like a great thing to do, which is why this box is so large and inconvenient. Some sites will completely block your access, but I'm not doing that - I'm appealing to your good nature instead. Did you know that you can allow ads for specific sites, whilst still blocking them on others?

Thanks,
Ian Williams aka Fetch
or for an ad-free Fetcheveryone experience!

The ACSM suggest that 40% VO2 max corresponds to 55% HR max, 60% VO2 max corresponds to 70% HR max, 80% VO2 max corresponds to 85% HR max and 85% VO2 max corresponds to 90% HR max.

RA says this for a run which is shown in their tables as having a VO2Max of 51.53:-
Correction: based on heartrate

There exist several studies to approximate a relation between %HRmax and %vVO2max. Because of a lot of influencing factors these computations are not always accurate.

Heart rate 77 %HRmax
equals 71 %vVO2max

⇒ VO2max56,49


Correction: based on correction factor

To consider some individual factors, we use a correction factor.

Correction factor0,91⇒ VO2max51,53
uncorrected56,49

So they're saying there's a calc which derives 56.49 and then converts it via 0.91 to 51.53.

The bit in bold certainly appears to be drawing a link between HRmax and vV02Max rather than straight between HRMax / VO2Max. But it's not entirely clearly laid out so I could be wrong - they definitely introduce vV02Max though as a factor.

(We'll ignore the fact that 0.91 * 56.49 actually equals 51.4 rather than 51.53!)

I missed they were using vVO2Max. What I said still pretty much fits though but can be refined a little. Your average HR for the run as a %age of HRmax is equal to a %vVO2 Max. This then suggests that they are saying if your avg pace at %vVO2 Max = X, then your VO2 Max must be Y.

Might go some way to explaining why it moves about so much...

Having been relatively diligent about Zone 1 and Zone 2 work last summer, from November onward I've moved towards a more marathon specific schedule. Now working through P&Ds 18 week programme.

Was late out last night so ran my first specific Z1 run in months as a recovery run. Just noticed that it was exactly the same route totalling 4.25 miles, and at exactly the same heart rate (128 bpm then / 127 bpm now), as a run I had in late October.

Last nights run was over 6.30 minutes quicker (11.23 /mi then 9.56 /mi now).

Doubt I should read anything into one run, or even if there was anything to read into it. The scale of the difference just caught my attention!

Hopefully TBR. I thought I would have gone the other direction through neglect if nothing else!

That's a nice improvement - hopefully something you can verify on your next couple of recovery runs.

I saw this on a Facebook group and thought I'd post it here. It's apparently from a book called "Training for the Uphill Athlete" which I think is mainly aimed at mountain runners/skiers, but some interesting graphs.

Everything you need to know about training with a heart rate monitor. Remember the motto "I can maintain a fast pace over the race distance because I am an Endurance God". Mind the trap door....

Gobi lurks here, but for his advice you must first speak his name. Ask and you shall receive.

A quote:

"The area between the top of the aerobic threshold and anaerobic threshold is somewhat of a no mans land of fitness. It is a mix of aerobic and anaerobic states. For the amount of effort the athlete puts forth, not a whole lot of fitness is produced. It does not train the aerobic or anaerobic energy system to a high degree. This area does have its place in training; it is just not in base season. Unfortunately this area is where I find a lot of athletes spending the majority of their seasons, which retards aerobic development. The athletes heart rate shoots up to this zone with little power or speed being produced when it gets there." Matt Russ, US International Coach
