Vector chain analysis
Power doesn't start at the hand. It starts at the ground, and every joint it passes through either adds to it or bleeds it away. Xi Victor 3D traces that path in real time.
-
Ground reaction force mapping
Captures how force enters the body through the plant foot, the true origin of the kinetic chain.
-
Force transmission pathways
Follows that force up through ankle, knee, hip, spine, and shoulder as a continuous, visible path.
-
Joint force analysis
Flags exactly where a joint loses power instead of passing it on — the leak points coaching cues rarely catch.
-
Sequential force generation
Confirms segments fire in the right order — hips before shoulders, shoulders before arm — the sequence that separates efficient throwers from the rest.
-
Movement efficiency tracking
Scores how much of the force generated at the ground actually reaches the release point.
Sensor integration
Six channels feed the model at once. Each reading below is a live simulation, shaped to the same throw driving the 3D view above.
3D movement mapping
The same figure in the stage above supports full-body and segment-specific review: rotate around it, step through frames, or lay two attempts on top of each other.
Real-time motion capture
Renders the athlete's movement as it happens, joint by joint.
Multi-angle viewing
Switch between front, side, and top views, or orbit freely to the angle a coach actually needs.
Frame-by-frame analysis
Drag the timeline to hold any instant of the throw still and inspect it.
Comparative overlays
Toggle Compare to place a second attempt beside the first, in the same space, at the same scale.
Try it
Scroll back up to the stage. Drag anywhere on it to rotate the camera, scroll to zoom, and use the Front / Side / Top buttons for a fixed read. Switch on Compare to see two throws overlaid, phase-shifted by roughly a tenth of a second — exactly how a coach would line up two attempts to see where they diverge.
Biomechanical analysis
Every vector on the stage rolls up into numbers a coach can act on.
POWER OUTPUT OVER THE THROW
MOVEMENT EFFICIENCY
TECHNICAL CONSISTENCY — LAST 8 SESSIONS
JOINT ANGLE RANGE — THROWING SHOULDER
Tracked continuously across the motion, not sampled at a single point — so a restricted range shows up even when it only appears for a few frames.
Sport-specific applications
Built first for throwing sports, and rebuilt around the same force-chain model for anything else that moves power from the ground outward.
Throwing mechanics analysis
Breaks the full motion into wind-up, load, release, and follow-through, each scored on its own.
Release point optimization
Shows exactly where in space and time the arm releases the most power most consistently.
Follow-through assessment
Reads deceleration after release as an early signal for shoulder and elbow load.
Power generation sequence
Confirms the hips, torso, and arm are firing in the order that actually produces speed.
Technical consistency
Compares this throw against the athlete's own history, not just a generic benchmark.
Performance tracking
Keeps a running record across sessions so progress — or regression — is visible early.
Sport-specific movements
The same vector model retargets to jumps, kicks, strikes, and sprint starts.
Power generation patterns
Maps how force timing differs by discipline — a jump loads and releases far faster than a throw.
Technical requirements
Checks form against the standards that matter for that specific sport, not a generic template.
Performance standards
Benchmarks against age- and level-appropriate norms rather than adult elite data.
Movement efficiency
Flags where power is generated but never reaches the point of execution.
Injury prevention
Surfaces asymmetric loading patterns before they turn into overuse injuries.
Who it's built for
Athletes
- Understand exactly where power builds and where it leaks out of the chain.
- See the specific form change that changes the number, not just a general cue.
- Catch a loading pattern that's heading toward injury, before it becomes one.
- Repeat the mechanics that already work, session after session.
Coaches
- Replace a subjective cue with a force reading everyone can see.
- Lay two attempts over each other and point at exactly where they diverge.
- Track an athlete's technical consistency across a full season, not just today.
- Plan the next training block around what the data actually shows.
Organizations
- Apply one objective standard across every athlete in the program.
- Spend training resources where the numbers say they're needed most.
- Build an injury-prevention record instead of reacting after the fact.
- Track development and success rates at the program level, not just per athlete.
