I do.

I don't get it.

I have big plans for next April . . .

They are done at the highest power that allows the athlete to complete all six efforts.



Probably the shortest one that still allows the athlete to complete all six efforts at the highest possible power.

BTW, if you've got a history with 4 min intervals, you might find these studies interesting:

Of course!

I think 4 x 6min intervals would be better.

Funny coincidence that I must have like 3-4 athletes today with 8x4min (1min).

Apaprently you didn't read the paper by Steve Seiler that I just cited?

Awesome. I'm starting my training tonight. Please tell the pro tour teams that I'll be considering offers next spring.

Perhaps I'm trying to catch the red herring.

If I average 305 W at a HR of 165 that puts me at the same ratio 1.85. That ratio doesn't make me "elite". (Maybe it does!!!)

If I weighed 140 pounds & could push 350 W intervals that would make me fast, or maybe "elite".

So what's the point of tracking one's W/BPM? Improvements to muscular endurance?

You're starting to get closer ;-)

Their intervals are the same length, but with such a short rest period between them they're a completely different animal.

I have now :-)

So what's the deal with these 2x20min intervals?

I am beginning to wish Paulo was still MIA, and you were with him. You're not doing anyone any favors with the nonsense.

"People think it must be fun to be a super genius, but they don't realize how hard it is to put up with all the idiots in the world."

Strenght endurance? :-)

I had noticed, but thanks for the heads-up ;-)

The fact that this is an elite athlete is relevant only in the sense that some would argue that such further improvements are not possible (or at least not without resorting to either EPO or, better still, PowerCranks).


Assuming constant thermodynamic efficiency, VO2 is proportional to power, so power:heart rate is proportional to VO2:heart rate. In turn, VO2:heart rate is proportional to the product of stroke volume and a-vO2 difference (i.e., O2 pulse). Thus, an improvement in power:heart rate is indicative of an increase in stroke volume and/or a-vO2 difference (and/or an increase in thermodynamic efficiency). That's why I've been recording my power:heart rate during ergometer workouts for >20 y.

Dr A,

Interesting, Ironic at the same time.

Back in the 70's my running coach's favourite interval length when doing longer intervals on the track was either 1000m or 1200m which would and we would typically do 5 - 8 of these depending on what we were doing, with about a half a lap jog recovery. This lines up almost exactly with the times in the studies that you just linked.

For years I have been a big fan of the 4 minute intervals on the bike. It seems to be a good length of time that you can go almost all out, settle into a rythmn and then work it right to the end. When I am "On", 2 minutes of recovery is all I typically need, so again that seems to be matching up with what the papers say.

Great stuff. Thanks for the info

Having troubles keeping up? :-)

So what training effects does that metric leave out?

The fact that this is an elite athlete is relevant only in the sense that some would argue that such further improvements are not possible (or at least not without resorting to either EPO or, better still, PowerCranks).

The implication being that there is a theoretical w/bpm ceiling?

I would say the implication is that this elite athlete is already near "their" w/bpm ceiling.

Justin in Austin, get it? :)

Cool races:
- Redman
- Desoto American Triple T

The most important one for an endurance athlete: an improvement in metabolic fitness, i.e, in LT, will not result in an increase in the power:heart rate ratio.

Of course there is.

But metabolic fitness comprises those effects too.
