🚨NEW🚨⚽️ “ It is not possible to change the posture in football with COD, chaos... This is not track and field" YES ,YOU CAN!💥 STRUCTURE (Static) dictates FUNCTION ( Dynamic⚽️) STRUCTURE > TECHNIQUE ( overrated ?) on APT Enhance your STRAIN margin of safety with ⬇️ APT

YES! Dynamic & static APT can be CHANGED on contextual football drills (surviving chaos) meanwhile training football DURING season💥🔥 Easily integrated into microcycle and part of the success of the teams with the fewest injuries in Champions 💥 STRUCTURE dictates FUNCTION!🧠

Sprint posture and football ⚽️🚨 Major new study by ZENTRUM SPORT Much more than “non specific linear sprint mechanics” These guys are just pushing our field ✅💡🤩 Read at Journal of Sports Sciences 👇🏻

The Ken Clark, PhD video was useful for elite athletes, but it can also be used for high school sprinters as well. Next month, a 3D model with foot mechanics will be made available for all sprint coaches with automatic reporting using affordable motion capture.

A little easier to "spring forward" when you wake up to something like this! Awesome to see Brendan (and Emmet!) at the top of #SCTop10 this morning. Thanks SportsCenter! #ILPL | #FightOnPenn 🔴🔵

🚨Sprint running mechanics are associated with hamstring strain injury. ⚠️Higher scores in the S-MAS➡️new HSI. ‼️1-point increase in the S-MAS➡️33% increase HSI rate. Dr Chris Bramah is changing the game👏 ✅The S-MAS can be easily measured in My Jump Lab Official bjsm.bmj.com/content/early/…

Tangential Foot Speed- If you read the Ken Clark, PhD study on ground speed compared to horizontal foot speed (negative) the relationship is very clear, if you don’t have the juice, it’s hard to run faster due to braking. The key is hip torque, and even elites are deficient. 🧵

‼️Speed testing can waste time if misused. ✅Instead, assess sprint gate health—this should automatically develop performance. If not, something’s off. We all have step asymmetries—one leg pushes, the other prepares. Normal. But elite loads can compress joints/pelvis and

The Ken Clark, PhD study illustrated some great points to velocity versus technical considerations. How to use this information? Model your program don’t sprint profile! Map out how you take testing and training data and modify the workouts. Forecasting speed is key.
