Discussion: Very impressive especially ...

Very impressive especially when it goes full speed (btw, both of these seem to be drive phase). My question is if there would be more power if you didn't arch and raise your lower back so high, it seems like if you kept your knees more bent and your lower back a little lower, there would be more power. As it is it looks like you are keeping your torso doubled over intentionally/artificially rather than as a natural outgrowth of a dynamic movement. Little do I know, hence I must ask.

Good observation- I feel this is so, especially as I try to convert to motor memory to stay low.
Hopefully I've fixed the uploads to reflect the initial set to go phase in one. The other slightly longer pans out.

Not that I know much about this, but it seemed you were scrunched up. Torso too high as mb says and also legs too bent. Slightly more extended legs maybe? Neat pics though to show the detailed aspect of the start to study.

According to my trainer the angles were good. Maybe I could go a bit higher with the hips. Good news is I am pushing out rather than stepping out, however first foot contact seems too close in. Some fine tuning from this foundation!

Fun stuff. Keep working on it.

yeah, you gotta do what feels right for you. and what your trainer thinks! I watched a few slow mo vids of world class sprinters and your form actually doesn't look that different. the only thing I noticed is that w a lot of them the angle of their torso opens up a tad more, even if they keep their head down, as early as the first stride, not sure why. go get em!

Thanks guys. The goal is to find a way to get out fast and utilize the ATP system in the first 50m - as a strength 400 rather than a sprint speed 400 type, that will help optimize my performance in the first 200m.

Another thought occurred- the more crunched up position is akin to a coiled spring- gets the explosive action!
The one thing I don't do well is transfer power down like a sprinter, rather adopting a middle distance stride out style. The former is the goal.
