New article for @SportsmithHQ detailing some of the work from our 🏈 sprint project. How do considerations of monitoring & developing acceleration change for different playing positions? @jb_morin @KenClarkSpeed sportsmith.co/articles/initi…

Initial acceleration in American football: How body mass influences the f-v curve - Sportsmith

Training initial acceleration (0–10m) with the same approach across every position group in American football is likely a mistake. Uniformity in training overlooks a straightforward biomechanical...

Fantastic paper by @KenClarkSpeed et.al that emphasizes there are many ways to solve the acceleration problem, there is no single "perfect" strategy or a single "ideal" technique, even at the very elite level. tandfonline.com/doi/full/10.…

Yesterday, @KenClarkSpeed published a new paper analyzing 0-10m acceleration in 24 elite American sprinters (51 Olympic/World Championship medals combined). Today, here's one coaching takeaway: Don't coach 30 athletes every rep. Pick ONE technical focus. Watch FIVE athletes. Coach that detail. Repeat. He also explains why longer contact distances in team sport athletes aren't automatically a flaw.

🚨NEW STUDY - Pre-PRINT🚨 Sprint running (max and submax speed) is a great plyometric stimulus🏃🏻🦵: direct comparison of ground reaction force-time w/ classical plyometric tasks. Read our new study (Pre-print) by @CriFubiani et al. here & send feedback🙏: researchgate.net/publication…

language around this comes from the work of researchers like Weyand & Clark, who have done a lot to explore both the drivers of speed and the mechanisms that help explain them. And like all science, this is an ongoing process. We refine the model, keep learning, and keep

organize the skill at high speed. Force matters a lot, but it doesn’t exist in isolation. Limb repositioning speed matters because it sets up the strike. Read @kenclarkspeed work on “whip from the hip.” What happens during the collision is essential as well… A lot of the

A follow up to the previous video… While force is STILL king…it’s a simplification, and I wanted to add some nuance. Speed isn’t one variable. It reflects force output, limb mechanics, posture, timing, coordination, tissue qualities, and the nervous system’s ability to
