WRITING

Sport science and rehabilitation — written to be applied.

Articles on force-velocity science, training methods, CMJ mechanics, sprint science, injury rehabilitation, and return to sport. Written for coaches and athletes who work with real people.

SPORT SCIENCE & TRAINING
Why your force-velocity profile is not a training prescription
The FV profile tells you where an athlete sits on the force-velocity spectrum. It doesn't tell you what to do about it. Here's the distinction that matters.
The countermovement jump is not one jump — it is four phases
Most coaches look at jump height. The real information lives in the unloading, braking, propulsion, and flight phases — and what each reveals about an athlete's force production strategy.
Hatfield squat mechanics and the accentuated eccentric — what the research actually shows
The Hatfield squat has gained traction as an eccentric overload tool. Here's what the biomechanical literature says about why it works and where it fits.
Velocity-based training is not just for the weight room
VBT gives you real-time readiness data. When you understand what the numbers mean, daily training decisions become a lot less guesswork.
Why we design custom testing batteries — and why standard protocols miss the point
A fixed testing protocol tells you how an athlete performs on the test. A custom battery tells you what you actually need to know about the athlete.
Wolfgang Taube's work on neural adaptation — and what it means for your warm-up
Neural adaptations drive early strength gains. Taube's research clarifies the timeline and mechanisms — with real implications for how you structure the first weeks of training.
REHAB & RETURN TO SPORT
Return-to-sport testing — what the criteria actually measure and what they miss
Limb symmetry index is the standard. It's also incomplete. Here's what a more comprehensive RTS framework looks like when performance science and clinical PT work together.
Training through injury — how to manage load without losing fitness
Injured athletes don't need to stop training. They need smarter programming. Here's how we approach load management during recovery.
The gap between discharge and performance — why most athletes aren't ready when they think they are
Clearance from a clinician means the tissue is healed. It doesn't mean the athlete is ready to perform. Here's the difference — and how to bridge it.
