Going to 11.

The height seems to make sense, but the wave length?

Clemson, I have a feeling that CNS amplitude has a direct correlation to level of impact. The variables are surface, footwear, velocity and time.

So, I guess once you get up to a fairly fast pace in warmup strides, staying on grass and in flats would spare the CNS in one way. Would the fact that you would have to push harder to reach a certain speed be more muscularly taxing then CNS taxing since your still reaching the same velocity and time as if you were warming up on the track in spikes? Would this then mean that during the warmup to help balance things out, you should maybe stay on the grass longer to warm up before your going to do a session of flying 20s, but get on the track earlier if your going to do a speed endurance day?

3: If Special Endurance qualities were the determining factor at the finish, then Marita Koch would have run away from Marlies Gohr over the 100m.

This poses another interesting question.

If speed endurance hinders top speed…How was it possible for Carl Lewis to run a 19.7 and still run a PB 9.92 during the Olympics?

Does it not take a high level of speed endurance to run a sub20? If yes, why did that 200m speed endurance not affect his 100m performance negatively? [/quote]

I completely agree with Charlie here.
Marita Koch was usually better than Marlies Göhr at mid-race point at 100m. She reached her maximum speed sooner than Göhr, and Göhr had a better speed maintenance. This sound surprisingly as Koch was 400m WR holder!

We can find EXACTLY the same example with Evelyn Ashford and Chandra Cheeseborough: Chandra used to lead Evelyn during the first half, she reached her max vel. very soon, and let Evelyn fly away, even if Chandra was training for 400m (11.13, 21.99, 49.05).

An other example: Merlene Ottey vs Irina Privalova: we know Privalova 400m background (48.47r, 49.89, 50.23i), during 100m races, it was the same scenario that the other examples.

It was also the same at 200m, Koch, Chesseborough and Privalova led some great 200m races after the bend, but showed shortcomings in the straight, when specific speed endurance plays.
Obviously, that’s SE isn’t linked with 400m abilities, at top level, of course.

On the other hand, Carl Lewis who had of course a very high level in speed maintenance at 100m, never showed great things in the last straight during 200m. Talking about Seoul, Lewis did 9.92 and 19.79.
Carl Lewis last 50m during 100m was exceptional (4.27).
His last 100m during 200m wasn’t great, 9.48, Joe DeLoach did 9.40 in that race, and MJ, Tommie Smith, Mennea, Fredericks, Boldon, Greene and maybe others have run faster than 9.48.

The greatest finishers at 100m are not always the greatest finishers at 200m.
