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 🔥

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.

If you reduce overstriding by 8 cm and increase projection by 8 cm, it appears that nothing changed with step length, but the net improvement is huge. Like body composition, you can gain 10 pounds of muscle and strip 10 pounds of fat, but the scale is not a true metric.

🚨NEW PAPER🚨 Resisted sprinting ➡️different sprint mechanics and running speed BUT when compared at the same🏃‍♂️speed, differences are only minor🧐 Confirms & extends results of 2 recent 📄 researchgate.net/publication/39… 👏@ssilva_edson & al.

Our conversation with @KenClarkSpeed was incredibly informative. He joined the Speed Lab podcast with @les7spellman and @danny_ruderock talk about all things speed - mechanics to force production to the science behind sprinting - it’s all in there.

The @KenClarkSpeed contact length ratio education is very useful if you know how to interpret the data. My main issue is the ability to drill down, as it's very labor-intensive and subject to seasonal changes and differences in practice versus meets. Only use validated data!

Hip torque for the win!
Sprint Science@spikesonly

When @KenClarkSpeed released his paper on thigh angular velocity, it got into some heavy math. The illustration reminded me of the 1997 Training for Speed book, & I thought of hip torque calculations from 2003 when I was editing the Forum review with @DerekMHansen years ago.🧵
