Tudor Bompa went after these guys. now the word is out. He won’t be invited to any seminars that they control.
Or cups filled with garbage. It has always seemed to me that facts/elements of the facts seem to fill the cup the least (as in they leave room for more). So if one’s cup is full, it is probably full of garbage. “The more one knows, the more that they know they don’t know…” I forgot who said it (Socrates?), but it is very true.
I believe the longer version of this last statement goes something like this: When you start something new you don’t know anything so you “don’t know what you don’t know”. When you study for awhile you know a thing or two so now you may “know what you don’t know”. And when one becomes a so-called master they “know what they know”. I like Bruce Lee’s version: “When I began martial arts a kick was just a kick. After I studied martial arts a kick was no longer just a kick. When I mastered martial arts a kick was just a kick.” 
I was browsing through training for speed and last night I read some of the comments about what you said regarding training with Percy. This was prior to your post.
No matter how much I think I know about speed training or training for sports, I keep having to refer back to my base texts to REABSORB the truth. It’s kind of like a physician peeking into the desk reference before the big surgery. Even like the preacher going through the Bible before his sermon.
Even when you are well skilled at certain things, the brain needs to be constantly reminded of what the truth is. This will be the fourth time reading TFS, and I guarantee I will find the need to highlight things I didn’t highlight the previous 3 times.
Things I did not understand I overlooked, things I did not believe (because of previous teachings clouding my view) I overlooked. It is my desire that I can read the whole book tommorrow without one time letting the brainwashing of others determine what I truly LEARN from the book.
You’ve just about summed it up…Rock on tommy!
If I ever went for the same position again I’m am definitely wearing a clown outfit! Of course they are a bunch of jokers.
Sorry to come back on this, but has this work been published?
Thanks!
Yes:
“High-speed running performance: a new approach to assessment and prediction.”
J Appl Physiol 95: 1955–1962, 2003; 10.1152/japplphysiol.00921.2002.
It was Socrates. And even Erykah Badu used that in her song "On & On.
The man that knows something, knows that he knows nothing at all.
Thanks, Bear!
Yes, that’s the one; I was just a bit surprised, because of what you said before: “Regardless, I don’t own the algorithm so I cannot reveal how it works yet. Hopefully, that will change in the near future.”, that’s all…
Again some people might have some arguments about the overall methodology used and/or the analysis for the agreement between the methods. Not to be pain in the ass, what’s published is published, of course!
“All” that’s left is to see the thing in practice!
Thanks again for bringing this to our attention!
Are you serious? Of course people on here will have arguments about methodology and/or analysis!
Naturally, they will be wrong

We hypothesized that allout running speeds for efforts lasting from a few seconds to several minutes could be accurately predicted from two measurements: the maximum respective speeds supported by the anaerobic and aerobic powers of the runner. To evaluate our hypothesis, we recruited seven competitive runners of different event specialties and tested them during treadmill and overground running on level surfaces. The maximum speed supported by anaerobic power was determined from the fastest speed that subjects could attain for a burst of eight steps (~3 s or less). The maximum speed supported by aerobic power, or the velocity at maximal oxygen uptake, was determined from a progressive, discontinuous treadmill test to failure. All-out running speeds for trials of 3-240 s were measured during 10-13 constant-speed treadmill runs to failure and 4 track runs at specified distances. Measured values of the maximum speeds supported by anaerobic and aerobic power, in conjunction with an exponential constant, allowed us to predict the speeds of all-out treadmill trials to within an average of 2.5% (R2 = 0.94; n = 84) and track trials to within 3.4% (R2 = 0.86; n = 28). An algorithm using this exponent and only two of the all-out treadmill runs to predict the remaining treadmill trials was nearly as accurate (average = 3.7%; R2 = 0.93; n = 77). We conclude that our technique 1) provides accurate predictions of high-speed running performance in trained runners and 2) offers a performance assessment alternative to existing tests of anaerobic power and capacity.

Experimental Design
Testing our first hypothesis required 1) obtaining measurements of the maximum speeds supported by the anaerobic and aerobic power of individual runners, 2) establishing individual speed-duration curves for each athlete, and 3) evaluating the agreement between the measured and predicted speeds for the all-out running trials completed. The quantitative expression of our hypothesis that the speed-duration curves of different runners would conform to a general relationship took the following form:
Spd(t) = SpdAER + (SpdAN-SpdAER)e^(-kt)
where t is the duration of the all-out run, Spd(t) is that speed maintained for a run of duration t, Spdan is the maximum speed supported by anaerobic power, Spdaer is the maximum speed supported by aerobic power, e is the base of the natural logarithm, and k is the exponent that describes the decrements in speed that occur with increments in run duration. We called the term Spdan - Spdaer the runner’s anaerobic speed reserve. The exponent k used for predictive purposes was 0.013. This was the average value of the individual best fits on data previously acquired from 17 subjects. None of these 17 subjects participated in the present study.
Testing our second hypothesis required 1) assessing whether high-speed running performances could be predicted from as few as two performance trials and 2) obtaining running performance data in the field to supplement that obtained in the laboratory. The speeds and durations of any two all-out trials, Eq. 1, and algebra could be used to create a system of equations, which, when solved, would predict the speed-duration curve from 3 to 240 s for individual runners.
In regards to the algorithm, the fit numbers look good. The experimental design looks pretty solid too.
Bear, as you use this model, i assume that it has generalized to your athletes well (otherwise, you wouldn’t be using it). Have you noticed any confounding factors that effect this algorithm’s efficiency? (Namely athletes with qualifications at the extreme ends of those tested in the paper)
So far I haven’t found any, but I haven’t worked with it long enough or with enough subjects to give a legitimate opinion regarding your question. Ken Jakalski, a coach in the Chicago area as used it much longer than I. He has not reported anything unusual to me.
For training purposes, it is very dynamic in nature because of its adaptation to changes in ability of each athlete.
This is what training sessions would look like:
Here’s a sample of the worksheet:
I don’t understand the second graph (or the first one really…). You input the Distance1, Time1, Velocity, Distance2, Time2, Velocity2, and the rest is pumped out onto the worksheet?
The 800m time is quite a bit off, though. most 60 second runners Guys or girls I know hit about 2:20-25 in the 800. I haven’t seen any algorith/program that can accurately predict times when switching energy systems. 100->800->10k. Regardless, it looks fairly accurate, and like one heckuva tool.
Daniels Running formula has a chart similar to this -and it helps oodles for doing trainig runs and intervals, but again it’s off depending up on the different event emphasis of the athletes.
Bear,
Are those distances you use to work out the aneraobic speed and aerobic speed 9m and 400m? Why 9 m?
And is the 400m flat out?
Do you test every session or only every X weeks.
Thanks
TC
Thanks for posting these and for responding. This type of model looks like it has a lot of promise.
Inputs are to distance and time only, velocity is calculated from them.
no particular reason for 9 meters other than as a short run test of anaerobic reserve. It could have been 3 meters or 6.8 meters, as long as they are flying so that they are at top speed. The 400 was just a time thrown in. It could be shorter or longer. For the initial test, 30-40 second runs (measuring the distance achieved) will give very accurate numbers for aerobic reserve.
In one sense, testing is constant, because you can adjust numbers after each workout. The green column nearest to the inputs can be change to any distance at any place on the column. They don’t have to be in order.
