Every tool in sport measures the result of a movement. KFA measures the internal stress behind it — and flags breakdown before the body shows it.
Cost is the internal stress behind every movement — and it compounds into breakdown before output ever dips. A pitcher can throw 98 and still be tracking toward failure.
Standard tracking captures velocity and spin — the result of the motion. It tells you what happened, never what it took.
The internal stress behind that output. A pitcher can sit at 98 mph (good output) yet be deep in the Cliff Zone for torque (high cost) — elevated risk, before any clinical symptom.
The cost was always there. Now it's visible — early enough to act.

No markers, no lab, no black box — every conclusion traces back to the physics. We trace force through the kinetic chain — ground to implement — exactly as it travels through the body.

Joint torque, kinetic-chain stress, and force sequencing from any source. No markers, no lab.
How pressure, decision load, and fatigue reshape mechanics — the dimension no wearable reaches.
Maps physical cost against performance, and projects the ceiling once mechanics are corrected.
Every athletic movement is a sequence: load and coil, then release through the kinetic chain. KFA measures each phase — where force is built, where it leaks, and where it lands as stress on the body.
Force moves through the body in a sequence. KFA reads each phase — then resolves the whole chain into two scores and fourteen tiered dimensions, the report you'll see next.
Every dimension and every score maps to a clear tier, so coaches and front offices know what to act on — and how urgently.
Every read resolves to two scores and fourteen tiered dimensions — and an audit trail behind them: graded input quality and a frame-level evidence log mapping every finding back to the footage it came from.
Compensated mechanics — trunk-mobility intervention indicated.
Cumulative cascade risk from a lumbar-extension restriction.
Before scoring the athlete, KFA scores the footage — how clearly the delivery is visible across every phase. A read only ships above threshold; below it, we flag the clip rather than guess.
Frames 847 / 885 / 901 span a ~27-second bullpen window. Citations reflect representative sampling, not single-pitch precision.
The full six-tab report adds data lineage, the AI biomechanical read, load-management periodization, and a projected ceiling.

A real case with an MLB organization. The pitcher and club are confidential; the sequence below is what we can share.
A pitcher was cleared to throw. Output metrics — velocity, command, workload — sat in normal range, and conventional tools showed no flag.
KFA read elevated injury risk before those tools did: BIV fell while CBS held, with risk rising across torque and fatigue and no clinical symptoms yet present.
We shared the read with the organization. The call was entirely theirs — KFA was one earlier input alongside everything their staff already weighs.
KFA doesn't make the call or replace the medical team. It surfaces internal stress sooner, so the people who decide have more time to decide.
The start was managed on the score alone. The pitcher returned his next outing and threw seven scoreless innings — and a later clinical evaluation confirmed the stress the score had measured.
One engine, one set of composites, delivered to fit how you already work.
Send the capture you already have — video, optical, wearables, biometrics. KFA returns finished, decision-ready reports, typically in under 24 hours.
The people who built the systems baseball measures itself with — and the pitcher who lived the cost they missed.
Former MLB first-round pick whose career was impacted by early UCL reconstruction. Holds a doctorate (D.Sc.) and authored a dissertation on the golf swing. Architect of the KFA Reasoning Engine and the CBS and BIV scoring frameworks — he lived the injury, then built the system to see it coming.
Thirty-year sports executive with 15 seasons at MLB Advanced Media building Statcast and the Automated Ball-Strike System — the systems that redefined how baseball measures the game. Leads product and strategy.
Legendary MLB pitching coach — 15 seasons with the Atlanta Braves, where his staffs produced multiple Cy Young winners.
Forty years as Head Athletic Trainer for the Chicago White Sox — one of the most respected injury-prevention careers in the sport.
If it moves, we can analyze it. The force chain is universal; the application is specific to each sport.
