I watched it this morning, but I don't have access to the video at the moment so I cannot remember everything he said. What I personally think is very informative is the 180 degree pivot. what he says (as far as I recall), If you turn 180 degrees (and stop there naturally), you have the right balance; too little = you are not using all the power available. Too much = off balance and you are 'doing other things' that could be affecting your throw.
I'll try giving it a closer listening soon, and maybe look into the whole CC options on youtube.
EDIT: Ok, I don't know how to do subtitles - so I will do a coarse translation here:
"Run-up is based on 3 simple basic steps: There are some physiological fundamentals we need to know and be aware of during the run-up; control, balance and coordination. I'll show some details that are worth keeping in mind when it comes to the run-up:"
"The most important thing is to not be stressed during run-up, in the beginning it is better to throw without a run-up than to proceed at too high a pace."
"during a run-up this is how it supposed to be: if you are right handed, your right foot will be finishing the movement and be the last step in the run-up" *demonstrates X-step*
"as you could see, the rotation occurs during my second step. Exactly where you put the second step does not *really* matter, but you need control. So you cannot put the foot too far back, because it will leave you out of balance - bend knees slightly" *does Xstep again* "right - left - finish"
"as i said before (ed: not during the video segment, though) it is very important not to have the final step too wide, because you will loose a lot of power. The idea is taken from spearthrowers, who focus on a powerful last step with your foot landing hard, which in turn will give a reaction force that travels into the hip and can be further developed into the arm. That is the basic idea."
"You can practice this separately standing still, and try to find the right feeling, the power in the hip. If you are doing it right, your midsection will get very sore due to muscle aches." (as in 'good' pain after exercising)
"In the beginning, in order to keep it simple, just practice the run-up by walking through it; one, two, three."
"here you can see my feet are just slightly wider than my shoulders. Not too wide, so you cannot gain maximum power, and not too narrow so you loose balance"
"Something important to keep in mind about the follow through; after you have thrown, you will automatically rotate around and land in this position. In order words, you are following through just as long as you where before your throw, like this:"
*spins* "Here you have control, the left side pointing straight forward, which before was pointing backwards"
"If you end up going to far - or too short - it means that somewhere along the motion, you have lost stability and or balance in this exercise, and the body will somehow try to compensate for it, either by releasing early or activating other muscles that have not been trained as well. (ed: there in something inaudible for me here, i think he is saying "...muscles not trained as well as you would in a normal muscle exercise" - but it doesn't make much sense, so I might very well be wrong). it increases the risk of injury and also lowers the overall power potential."
I hope this might help?
I hereby commit myself to actually do the drills, rather than just trying them for a few times and expect results.
