Javelin combines sprint mechanics with a technical throwing action. AI video analysis of approach speed, crossover steps, plant, power position, block, and release angle, with coaching notes on the specific frame that cost you distance.
Run-up consistency, carry position, acceleration.
Rhythm, hip-to-shoulder separation building.
Impulse stride, javelin laid back.
Full separation, javelin horizontal, left side blocking.
Up-and-through release, release angle, follow-through.
Generic video tools look at "a person moving." We built a model specifically around javelin, the phases, the mechanics, and the coaching language real javelin coaches use.
You upload the rep. We extract the critical frames. You get a breakdown in plain English with priority tags, what's critical, what's worth working on, what's fine.
These are the technique patterns we see over and over again across javelin athletes. Each one has a specific look on video and a specific fix.
Your tip drifts downward in the power position, flattening flight and cutting 5-8 meters on a good throw.
Carry drills with a tip-up cue, and plant-and-freeze reps to groove the horizontal carry.
Your arm fires before the block foot lands, leaking energy before the chain can transfer cleanly.
Delayed-arm stand-throws, focus on feeling the block foot first, arm second.
Your plant leg bends on the block, losing the deceleration that transfers momentum into the throw.
Heavy-block drills against a board, and single-leg Nordic work to groove a stiff plant.
From freshman javelin to D1 rosters, athletes upload phone video and get the same frame-by-frame coaching read. The AI doesn't grade you, it explains what it sees, in the vocabulary a real javelin coach would use.
