I never understood why focusing on the arm swing was that important. In fact I don't think focusing on it will make you faster. You should ask T0dday though he prob knows. I have not seen an intelligent argument for focusing on the arm swing yet.

  I would rather focus on arm swing if I was running at top speed, because I know the legs will do the work for me, it should come naturally.  

LOL I do the exact opposite, the converse actually. I deliberately try to make sure my strides are kicking out a bit, that I'm reaching just a little, and pulling myself forward, kicking knees up and then out as foot goes out, and so far from my vids my arms are fine. But certainly some people have horrible arm swing and thinking about it could improve legs.

However, I will try focusing on arm swing too and se what happens. sometimes my arms just want a workout so i feel like focusing on them more. Have you heard of the spiraling technique? I think tyson gay does that. http://trainoutpain.blogspot.com/2011/02/david-weck-spiraling-fascia-and.html

"twisting allowed for greater energy transfer."
-that sick3nv3nd3tta guy was right

Speaking of bad arm swings and fast sprinters though...

His arm swings are basically bicep curls. He's kinda hunched over and has a lot of anterior chain action going on. But that may help for shorter races.

Yesterday I did some more max sprints again. When I reach top speed I just focus on the beat of the stride. I did not say I feel the arm swing form my shoulders, but it could help. I just go like this once I reach top speed "dut dut dut dut dut dut dut ..." each dut being a stride. It feels great to be at top speed with good sustainable form.

I don't know if this has been mentioned but one coach said a test of your relaxation would be to sprint a 100m sprint with a piece of paper in your mouth. If you wre relaxed you wouldn't have bitten into it.

Those are some great quotes, i will have to check ou tthe links later.

Of course I cannot claim to be an expert as I have not even competed yet despite training 100m for almost a couple years now consistently, but I do claim to understand exactly what it means to relax in top speed. When I reach top speed I know it, it feels distinct from anything else. It's also very difficult to:
1. keep my head down
2. speed up strides

1. My body naturally becomes upright, and keeping my head down is more difficult. 2. The reason I cannot forcibly speed up my strides as much as I can in the fist 30m is b/c i'm up in the air more and thus my legs are going through more of a cycle motion rather than a kicking forward motion which I do for the first 10. Thus, when I get there after 50ishm, I just get into the form which I know so well now, and put as much power behind each stride as I can, one stride at a time. Edit: trying to do anything else just feels less ecnomical. I've tried t keep my heels lower by kicking more, but that just seems to fight air resistance and the upward motion of my body during each stride.

I am not completely sold that being relaxed will help, because I think another term one could use is awareness. If you become aware of how your stride feels once at top speed, you may realize that trying to fight it by speeding it up or clenching your teeth together doesn't really help, and is actually detrimental if it screwed up your form. But you can be aware and not wasteful of energy.

So memorize how it feels at top speed is what I am offering. To do this you cannot test out submax drills. It has to be 100% effort, but the awareness of form will be more relaxing than clenching the teeth and flexing the neck muscles.

it's slightly contradictory what he says. He says to work on good technique during an exercise, go lighter perhaps, and practice that, but that is making the weaker muscles in the movement stronger anyway.. he says this isn't about strength it's just about the motor patterns, but they are tied together.. I used to have valgus collapse during leg presses and squats but practicing with good form has completely cured that. I would say all I did is proper strength training with good form, which is also neuromuscular training.

Lifting fast is more specific, but does it result in the same improvements in performance?

What about superslow training? Any place for that in the explosive athlete's arsenal?

http://www.unm.edu/~lkravitz/Article%20folder/superslow.html

"In a muscle fiber, the slower the rate at which the actin and myosin filaments slide past each other, the greater the number of links or cross-bridges that can be formed between the filaments (Smith, Weiss, and Lehmkuhl, 1995)."

It's surprising to hear this but I might try superslow for a few reps from now and and see if it really  makes me superslow. I have a feeling though it won't make me as slow as I think.

little bit about that here: http://www.pponline.co.uk/encyc/explosive-strength-training-research-on-resistance-training-suggests-that-doing-less-is-more-41048

studies have already shown you don't have to lift aht heavy to gain optimal strength, lifting fast works.

THis article didn't mention my biggest problem with lifting, which was just addiction and burnout. i developed mild adrenal fatigue from training way too often. I had burning sensations in my eyes all the time, couldn't focus as well in class, and had trouble keeping my eyes open. training less, eating more, eating salt, helped. Aloowing my body to recover more basically.
