Universal intensity description for runners (%CV)

If some aren't available already, there should be apps that use GPS to track and graph speed during attempts at fast runs. The graphs would get flatter as the runner gets into shape.

Lexel, just quit LRC and get new username. You are cooked here. You have no credible left. You wear big clown shoes.

And i have the feeling you have not enough knowledge about training pysiology and try to compensate that by moving data around to make it more understandable for you. That methology does not bring you forward. Oh, and you can shove your first and any paragraph somewhere.

Do I have a PhD in Exercise Physiology? No, do I need to? If you’d like to define for me the standard I need to meet in order to have “enough knowledge about training physiology” to engage in these discussions, I’ll gladly concede ignorance if I fall short of your definition.

Moving data around to make it more understandable for myself? I’m not sure what you mean by that but I’m going to answer it assuming you’re referring to changing terminology, in some way.

Was it not common until recently for LT1 to be referred to as the Aerobic Threshold and LT2 to be referred to as the Anaerobic Threshold? Is it now not common for physiologists to call LT1 Lactate Threshold and LT2 Lactate Turnpoint or OBLA or MLSS? I’m neither inventing nor moving these terms around. I am however aware of the nuance and variation and can generally recognize what people mean when they refer to them without feeling the need to suggest they are “wrong” or that they “don’t understand.”

John Davis does have a PhD in Human Performance. When he used the term “anaerobic” to refer to speeds at or faster than CS, I assumed (albeit with my deficient foundation in exercise physiology, of course) he was referring to the fact that blood lactate would be accumulating at a higher rate than it is being cleared, thus having crossed what many referred to (and some still do) as the anaerobic threshold.

Should I summarize glycolysis, and the conversion of glucose to pyruvate to lactate and how that lactate can then be shuttled back to the mitochondria to be used as fuel for the cell, but that when too much lactate spills from the muscle to the blood, in order to sustain plasma electroneutrality, hydrogen ions increase to counterbalance the elevated lactate levels and it’s partly that presence of hydrogen ions which leads to muscle fatigue? Asking for a friend.

Said friend would also like to know how knowing that makes any difference in the practical application of determining training zones based on LT1, LT2, CS, heart rate max, or any other parameter yet to be defined. Thanks.

Davies PDF is a good step forward, not by chance it is also inspired by my previous messages and the percentage works of the Italian school. It’s a good approximation because it already takes the areas from the mile up to 7 km and it speaks for the first time for Anglican authors of rhythm customization.
My way is even more precise because I take into consideration all the areas, from the alactic as the 10-66 meters, to the lactic as from the 66 meters up to the 3000 meters and the aerobic ones, up to the marathon and beyond.

Dimitri,

1) What is your work about?

2)Any scientific papier, correlated to your mentioned Italien experience? Why has Italien then not the best Marathon runners ?

3) What has your work to do with %CV?

As Tinmans internet CV calculator is down for whatever reason, i can offer you to provide a CV table based on IAAF score and your 5k race time/TT.

If you are interested upvote this post, if not downvote it (as usual :)).

I will wait 1 week from now and do the work only if the overall result is positive.

Lexel, I really hope that it not fake you a week to do that, something that could have been put together 90 seconds. Your obsessions with CV has diminished what you could be learning. If anyone wants a usable PDF, Hard2find I believe made an awesome one with the different thresholds for different distances. Very good use. Also, in other thread on tinman , someone provided offline calculator for old tinman. So like I say, I hope you didn't spend very long doing this. You obsessions with CV is probably why you cannot break 20 min.

Thanks Lexel, this table is awesome.

Lexel, MLSS is clearly and succinctly defined.

Also, CV is individual. Economy factors into how fast you run.

Skip lactate testing. All-out time trials are better. No better way to determine performance than the performance itself.

Good try, though. These folks aren’t ready for CV/CP.

MLSS is absolutely arbitrary defined (i.e. less than a 1 mM increment in blood [lactate] between 10 and 30 min), that is the weakness of it and is very well discussed in this paper

ncbi.nlm.nih.gov

Steady-state [... formula ...] above MLSS: evidence that critical speed better represents maximal metabolic steady state in well-trained runners

The metabolic boundary separating the heavy-intensity and severe-intensity exercise domains is of scientific and practical interest but there is controversy concerning whether the maximal lactate steady state (MLSS) or critic...

Lactate measurements can have still their value in my opinion, but not isolated, as an addidition, if done correctly. I agree that all-out time trials are good.

It is correct that economy factors are there, thats why it is an estimation and fine tuning might be needed. However, still a good starting point and orientation.

Folks are absolutely not ready for it :))

Remark: There are some people here who use it already silently ...
