IMO one of the most useful tools to assess sprint technique is the SMAS from Dr Chris Bramah. No fancy tools needed except a camera. The more we find these positions, the worse the score gets. Poor performance = excessive anterior pelvic tilt, lack of elasticity/coordination, etc.

🚀 Acceleration & Sprint Profiling – Made Simple! Inspired by the work of Ryan Grubbs dpfaff JB Morin Ken Clark, PhD James Wild Ryu Nagahara Helen Bayne ………… This 3-min video breaks down key metrics for 10-20m sprints (static or flying). Originally built for me to

Athlete's with better reactive strength abilities (measured via 10-5 rebound jump test) demonstrate shorter ground contact times in late phase acceleration

Sprint Mechanics & Hamstring Injury Risk From JB Morin When it comes to sprint performance and hamstring injury prevention, small mechanical adjustments can make a big difference. Research from Dr Chris Bramah has shown that just one degree of anterior pelvic tilt is associated

🔎 The Final Barrier in Hamstring Rehab: Neural Inhibition & Sprint Confidence This player has elite strength scores, completed a full running progression, yet still lacks confidence in sprinting due to persistent discomfort. 📌 Top Video: ✅ Good running mechanics, clean

0.16s faster over 10m! 💨 Nothing fancy really but consistent work lifting weights, sprint twice a week and drills, but making every rep count. The speed journey continues with Speedworks Training and vuemotion for what’s next! 🚀

Do we slow down with age? In general yes —but it depends on how we’ve trained. I see athletes near 40 still making big speed gains. Resisted sprints, technique, strength, hip control & max effort sprinting all make a difference. Train smart, keep getting faster!

If I was working in a team setting and tasked with “speed development” — this is where I’d start. Not just drills or max velocity exposure… But building a system around profiling, monitoring, and integrating speed into practice, rehab, and planning.

10/5 rebound jump test isn’t just a number—it’s a lens I use to profile athletes. Use it to spot how well an athlete handles fast stretch-shortening cycles, then tailor plyos accordingly. Profile first. Prescribe second. Thanks Eamonn Flanagan, Sportsmith for a great course

Simple plyometric coaching progression: ✅ Low intensity skipping ✅ Vertical "power skips" ✅ Short bound ✅ Bounds or hops for distance Appropriate entry points for athletes of all levels.

Adopting an adaptation-led approach to programming with Alex Wolf – one of the best podcasts I’ve listened to in 2025. It really made me reflect on how I approach programming. thx Sportsmith open.spotify.com/episode/2uuErD…

There was a large (but non-sig) correlation btw RSI & Sprint-CT @ 20-30m (r = -0.584) Reactive strength is likely a key strength quality for mid-late phase sprint acceleration A reduction in Sprint-CT may be the mechanism by which RSI positively influences sprint performance

MD-2 max speed testing with Lionesses as they prepare for their opener v France tomorrow evening. Research shows that players who hit >95% of their max speed 1-2 times per week are less likely to suffer a muscle injury then those who reach <85% or less. Load the hamstrings.
