Got some great work in with @KenClarkSpeed and @paulkenny_speed It was great to see my form compared to college and professional track and football athletes. Excited to keep working and getting better!

🚨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🙏:

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

Another great topic with @KenClarkSpeed & @korfist — Contact Length (or contact distance)
A simple ratio metric to help you better understand how an athlete is contacting the ground and the efficiency of their stride mechanics 🔥

Appreciate it @sprintcoachSWE !!
Always good to see confirmation of the data/concepts.
Huge fan of your work!

Rapid Fire: 60(ish) seconds of complex topics made simple with @korfist & @KenClarkSpeed .
Ken Clark breaks down how to measure vertical force production. No force plates embedded in your track needed!

Thank you, @zentrumsport and @KenClarkSpeed, for the recent research that is guiding the football project.
Tangential Foot Speed
Structural Transfer
Fluid Conditional Logic
Practical use of IMUs
If you are stuck on single magic bullet ideas with exercises or drills, move on.

2025 was an incredible year with so many awesome opportunities and a lot to be thankful for. I’m very appreciative that my position at West Chester University allows me to teach, conduct research, coach speed, and consult. Thank you to everyone who made this year possible!
