I don't think you need oxygen to 'burn' atp, but you sure do need it to produce it. The body can produce it for less than 2 minutes without oxygen. I think the process goes atp stores for 2 seconds, creatine phoshate for 5 seconds, then lactate sources for about 90 seconds. But there's a catch. Once you start depleting these sources, the body regenerates them and that consumes oxygen. Processes like gluconeogenesis that turn lactate back into usable fuel consume oxygen.

In a nutshell, even 'anaerobic' processes use oxygen, they just don't do it directly and they are not particularly efficient. In fact, it's all that aerobic based muscle tissue and those aerobic pathways you've been working on that does the bulk of this job. Nothing comes for free, and 'muscle power' ultimately needs O2 to even exist.

Re: Improving running economy redux...

Here is some information on ATP production that even Richard can understand.

http://health.howstuffworks.com/sports-physiology5.htm

http://static.howstuffworks.com/gif/sports-physiology-atp.gif

Exercise and Aerobic Respiration

+By two minutes of exercise, the body responds to supply working muscles
with oxygen. When oxygen is present, glucose can be completely broken
down into carbon dioxide and water in a process called aerobic respiration. The glucose can come from three different places:+

  • remaining glycogen supplies in the muscles
  • breakdown of the liver's glycogen into glucose, which gets to working muscle through the bloodstream
  • absorption of glucose from food in the intestine, which gets to working muscle through the bloodstream
+Aerobic respiration can also use fatty acids
from fat reserves in muscle and the body to produce ATP. In extreme
cases (like starvation), proteins can also be broken down into amino acids
and used to make ATP. Aerobic respiration would use carbohydrates
first, then fats and finally proteins, if necessary. Aerobic
respiration takes even more chemical reactions to produce ATP than
either of the above systems. Aerobic respiration produces ATP at the
slowest rate of the three systems, but it can continue to supply ATP
for several hours or longer, so long as the fuel supply lasts.+

Re: Improving running economy redux...
In defence of Richard (can you flipping believe this!?), I think he's trying to say this "old-fashioned traditinoal conventional" thinking is wrong. He's trying to say (and here's my assumption gets a bit foggy because he hasn't clearly stated it yet...I don't think) that, because the need of oxygen decreases...as your running economy improves...which is accompanies by improved performance; therefore, oxygen is not necessary (or at least increase of oxygen intake). You can run even better with less oxygen. On the other hand, improvement in muscle power (he states "any power increase" which I think is quite rough assumption) actually improves running economy; therefore improving muscle power is more important than improving oxygen intake in order to run faster. Is this correct, Richard?


Well, firstly, if this is correct, he is not looking at a bigger picture. Just because little Japanese Honda car has better gas mileage (economical), that doesn't mean you don't need gas. Or better yet; you bring some old-fashioned 67 Mustang with gas-mileage of like 3 (!); put them side by side and have them run a mile... Guess which one kicks a$$?

I think, in a way, it's admirable that he's trying so hard to "update" the running universe with the most up-to-date research papers. But 1) some things don't need to be updated. Who came up with a better shape for a wheel than round in the last 50 years? Does it have to be updated? And 2) as Richard himself admitted, quite often researchers/scientists are wrong and, as they find out their own mistakes, they'll switch the information right to left. As that happens, everything would have to start all over again. That's fine and the actual papers and such may need to be updated, thanks to the misinformation. But in running, at least in the practical field, what works is what works. Whether lactic acid is an enemy or a friend, what Lydiard termed "anaerobic training" still works to make runners to go faster. His explanation on 50/50 might have been wrong but we still use it and get results.

Re: Improving running economy redux...

Richard just wants to somehow make it look like oxygen isn't that important in running, and he's trying to use running economy to support his case. He avoids discussing why economy improves and just wants to use the 'same pace at less oxygen' aspect of it.

You can reduce oxygen use by simply not bobbing up and down as much, not overstriding (and having to recoupe the momentum lost as a result) or even not move your arms as much...all sorts of stuff Do any or all of those things and you can run at the same pace with less oxygen consumption. No secret there. These steps will improve running economy and don't involve any changes at all to running muscles.

You can't make any given muscle tissue produce more power without consuming more oxygen. It's as simple as that. Running economy doesn't contradict any of this because running economy is all about eliminating wasted energy, not producing more energy from given muscle tissue on less oxygen...this just doesn't happen.

Get rid of sources of wasted energy. Then maximize the use of slow-twitchers over fast-twitchers because they're more efficient users of oxygen beyond that initial 2 minutes of running. After that, to get faster means more oxygen, so build that mitochondria and build those capillary beds, increase the stroke volume and do all those things to get more and use more oxygen.

Re: Improving running economy redux...
Even if we have outdated old-fashioned terms, they can be of some use. We say, "Ah, did you see the sunrise this morning?"

We do not say, "Did you observer the result of the earth's rotation, and the light rays penetrating the atmosphere at an acute angle amidst scattered cumulonimbus, cirrus, and windborne atmospheric dust?"

We may just as well say, "Run hard today, to get up your gumption for racing." And, "Run long to get the guts tough for a marathon."

Science is great, but it is not required for great training, nor for physical adaptations to occur. The compenduim of great athlete's training is all I need for research.

Re: Improving running economy redux...
Jim:


Do you remember that Chinese woman who runs with very awkward looking arm swing (or not-swing)? I think Sun something was her name. She is of course one of half a dozen women to have broken 2:20 barrier in the marathon. Apparently she didn't get picked to run Beijing by Chinese Federation (she's done with her ban). I wonder if her un-orthodox style of minimum arm swing has anythnig to do with her running economy... She runs very well--didn't she even medal in the WC in 10000 some years ago? She does swing her arms, mind you, when she picks up speed. It looks almost like she's disciplined to minimize her arm swing during the other non-critical part of the race... I don't know. I just thought about it. Lydiard always liked low arm swing. Peter Snell had low arm swing. I ran 1:40 yesterday with the lady I'm coaching (and we pushed quite hard and she nearly killed me!)--she has a low arm swing. I know I carry my arms a bit higher (normal height?) and I feel comfortable like that. But sometimes my shoulders do get tired. I always tell her that her style reminds me of Snell.

Heck, yeah (I can't say **** on here). When it comes right down to it, ya gotta do what ya gotta do to run fast. Who gives sh** if you have to suck air through your ears or you use twice the oxygen as the guy next to you to do it.

So long and good luck Dick. You're still a goofy bastrad and I'd love to haunt you a bit longer, but Active has killed the fun. I assume you'll figure that out and eventually bring your crazy a$$ ramblings to the growing fora that are replacing the once noble Coolrunning.

I have a theory that it takes more energy to keep your arms from swinging than it does to let them swing.


Hey Nobby, there was a section in the latest Runners World where one of the question/answer segments asked 'who do you consider the best coach'. In the response (not sure who the responder was), the author called Lydiard 'the father of long slow distance'.

Re: Improving running economy redux...

I hope Nobby responds to that last posting.

Ya see, I never understood that. I have read all of Lydiards books and never did I get him saying anything about running slow.He does say "you can't train to slow only to fast" so you can intreperet that as you will. My take on his training system is that you don't put the cart before the horse. In the beginning(chapter 1 nobby??)I think he would rather you not pay attention to pace or distance but just build up to where you can run long and run long often. I am finally seeing the importance behind this phase in my own training. But that is only ONE part of Lydiard training why are so many people stopping their and calling Lydiard LSD based off of that? After that point you run with effort, you run hard and train hard at some point. I guess when someone calls Lydiard LSD it's a little pet peeve of mine. Some people only see the parts of the picture they want to....thats fine but than they publish thigs like that and well....

Nobby,

What do you think of Ryan Hall's arm-carriage? You can appreciate the contrast with other top Americans from the OT (at, e.g., 2:50).
