Why Biomechanics

Volleyball Skill Lives in the Details

Most platforms track stats. We measure mechanics — the sub-300ms motions that determine power, consistency, and longevity.

The Spike is the Most Complex Motion in Volleyball

A successful attack requires synchronized hip rotation, shoulder internal rotation, elbow extension, and wrist snap — all within 150–300ms. Most coaches see the outcome. We measure the mechanics.

Kinematic Sequence Determines Power

Elite hitters generate force through a proximal-to-distal sequence: hips fire first, followed by trunk, shoulder, elbow, and finally wrist. A breakdown at any link bleeds power and increases injury risk.

Poor Mechanics Cost Careers

Shoulder impingement, rotator cuff tears, and ACL injuries in volleyball are overwhelmingly biomechanical in origin. Real-time joint angle tracking and valgus alerts let you act before the athlete breaks down.

What You Can't See, You Can't Fix

The human eye can't track 300ms motions at 30fps. AI frame analysis captures what coaches miss: arm swing path deviation, asymmetric hip loading, inconsistent approach timing, and contact point variance.

Each segment accelerates and decelerates in sequence. Spike Science measures timing and velocity at every joint transfer point, identifying exactly where your kinetic chain breaks down and how much power you're leaving on the table.

Platform Features

Everything Built for Serious Volleyball Athletes

Nine integrated modules. One platform. Clinical-grade data from any phone video.

BIOMECHANICS

Frame-by-Frame Joint Analysis

Every rep analyzed across 33 body landmarks. Elbow angle at contact, shoulder abduction, trunk lean, wrist snap velocity — all captured from phone-quality video.

KINETIC CHAIN

Full-Body Power Flow

Visualize force traveling from foot contact through hips, core, shoulder, and into the ball. Identify where energy leaks and what costs you swing speed.

AI COACHING

Automated Coaching Cues

Position-specific feedback tied directly to your measured deviations from elite-range benchmarks for your position. Not generic tips — precision cues.

INJURY PREVENTION

ACL & Shoulder Risk Scoring

Real-time valgus collapse detection, asymmetric loading alerts, and cumulative load forecasting (ACWR). Know your risk before you feel it.

MULTI-PLAYER

Persistent Player Identity

Track up to 6 players simultaneously with individual ID persistence across the full session. Each player gets their own metrics and session history.

POSITION INTEL

Position-Specific Benchmarks

Separate metrics, ranges, and performance ceilings for OH, Setter, Libero, MB, Opposite, and DS. Generic data misses position-specific demands.

TRENDS

Long-Term Development Tracking

Compare mechanics across sessions. See which joints are improving, which have plateaued, and how your power curve evolves over a full season.

WORKOUTS

Personalized Training Prescriptions

Training plans generated from your biomechanics data. If your hip rotation is limiting arm swing, you get targeted mobility, strength, and plyometric protocols.

TEAM ANALYTICS

6v6 Team Intelligence

Upload full match film for team-level analytics: rotation efficiency, attack distribution, dig coverage, and opponent scouting reports.

Position Intelligence

Built Around Your Role on the Court

Generic biomechanics platforms miss position-specific demands. We don't. Every position has its own metrics, benchmarks, and AI analysis engine.

Personalized Workout Prescriptions

Training Plans Generated From Your Data

After each analysis session, Spike Science generates a training prescription mapped directly to your biomechanical findings. If your hip rotation restricts your arm swing, you get hip mobility protocols. If approach timing is off, you get plyometric sequencing drills. Every plan is position-specific and periodized.

Plyometrics
Phase-based vertical jump protocols built around your GRF and approach mechanics
Mobility Rx
Hip flexor, thoracic & shoulder mobility tied to your specific range-of-motion deficits
Kinetic Chain Drills
Sequencing drills to correct proximal-to-distal breakdowns found in your swing analysis
Injury Prevention
ACL prehab, rotator cuff stability & asymmetry correction from your risk scores
