Very interesting study on resisted sprint by Pedro Jiménez-Reyes et al. good using a "phase-specific approach" 💡 Good to see the standard of "%Velocity decrease" getting more and more attention ✅ Open access 📄🔬 frontiersin.org/journals/sport…

Pedro Jiménez-Reyes (@peterjr49) 's Twitter Profile Photo

Thanks for sharing! Hope we can present very soon our data about adaptations under different specific training stimuli with “%velocity decrease” as reference. Stay tuned. Let’s go with this interesting practical approach. VBT in sprinting 💪😀

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!🧠

We made it, my friend. Through research, discussions, and clinical work, you told me years ago that we had to do it. Today, it's published, but the true value lies in the process and the journey, that’s what really matters. Huge thanks to Pedro Moreno Pedro Jiménez-Reyes Adrián Moro

Amazing work! Congrats Andrea Astrella !! Well deserved and thanks for your dedication and patience in this amazing journey. Some said it wasn’t possible… but here we are, proving that hard work & the right process lead to change. Still more to write, but this is a huge milestone!

Huge thanks to ZENTRUM SPORT , Andrea Astrella , and the incredible team Pedro Moreno, Adrián Moro, and everyone involved. Your dedication and expertise made this possible! We believed in the process, and this is just the beginning! More chapters to write. 🚀

El lunes pasado tuve la suerte de escribir unas palabras en El País sobre la retirada de Bruno Hortelano. Como muchos no podéis acceder al texto completo, comparto aquí mis palabras. Porque este momento es especial, y Bruno lo merece.

🚨NEW🚨 Better accel perf after resisted training at individual 50%Vdec load in🏉✅ For the same volume (200m/wk), short (12.5m) vs longer (20) sprints = same results, interesting for planning 🧩 Nice collab w/ Matt Cross Pierre Samozino &🇮🇹 colleagues pubmed.ncbi.nlm.nih.gov/40441718/
