if you can pre-t turn the pelvis with a lot of lordosis in the spine you get much more power development behind the center of mass through the extensor range

The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
the 100 meter men and women they you will find they have a lot more lordosis than the runners yeah they have a and what that does uh I'll just explain the running mechanics here for a minute so if you're running along you have a center of mass you have to bias the force under your feet behind the center of mass to propel you forward because if it's in front of the center of mass you're actually breaking which wouldn't win you a gold medal so footfall has to occur behind the center of mass and then you get a very brief period of time to create an extensor pulse and then recover the leg if you can pre-t turn the pelvis with a lot of lordosis in the spine you get much more power development behind the center of mass through the extensor range if you have a flatback it's difficult now you've just shortened up the range that you can pulse into propulsive forces a Sprinter turn B the body yeah but you'll notice it's very difficult for a sprinter to kick high so you'll you know I I look at these different forms in the combat athletes if you look at someone who can kick high in a round house they will tend to have a flatter back so combat athletes tend to have a flatter back going back to the runners you'll notice that the Michael Johnson's and the more the runners with more distance have a flatter spine they're more upright and they're tuning that uh uh ability to store and recover elastic energy where where the Sprinter out of the blocks it's horsepower it's concentric and Ecentric muscle pulsing but uh anyway there there there would be uh an example since you you mentioned it with running uh the the style of running the event they're not running isn't running running is very different and again look at the podium winners of the sprinters versus the 10,000 meters very different architecture
if you have a flatback it's difficult now you've just shortened up the range that you can pulse into propulsive forces
