Backfield x Output Performance Package
Measure Your Athleticism. Build Your Baseline. Track Your Progress.
Velocity testing session using Output Sports sensors + Backfield performance analysis.
OBJECTIVE SNAPSHOT
Know exactly where your performance stands
The Backfield x Output Performance Package gives athletes an objective snapshot of their physical performance using wearable Output Sports sensors.
Instead of judging athleticism by feel alone, we measure key qualities such as explosive power, reactive strength, movement velocity, force production, mobility, and strength performance.
Your results are added to your Backfield athlete profile, creating a performance baseline that can be compared against future testing sessions.

High-frequency VBT accelerometer & force-time telemetry
ASSESSMENT PROTOCOL
What we test
Testing can include the following standardized evaluations:
Explosive Power — Jump Performance
Measure countermovement jump and squat-jump performance to evaluate lower-body explosiveness.
Reactive Strength — RSI
Evaluate how effectively the athlete can absorb force and rapidly produce force again during reactive jumping.
Movement Velocity
Measure how quickly the athlete performs selected strength and explosive movements.
Force & Power
Quantify force and power during selected exercises to better understand how the athlete produces athletic movement.
Strength Performance
Use movement velocity and standardized strength exercises to establish objective strength benchmarks.
Mobility & Range of Motion
Assess movement through key joints to identify limitations that may affect athletic performance.
Single-Leg Performance
Where appropriate, compare unilateral movement and jumping performance to identify meaningful differences between sides.
ORGANIZED PROFILES
Your Backfield Performance Baseline
Following testing, your results are organized into your Backfield athlete profile.
Instead of receiving a collection of disconnected numbers, Backfield turns your testing data into an understandable athletic performance profile.
Your baseline can include:
Explosiveness
Jump and power performance.
Reactive Strength
How effectively you produce force during fast stretch-shortening movements.
Strength
How effectively you produce force across selected movements and loads.
Movement Velocity
How quickly you express force during athletic movements.
Mobility
Range of motion across key movement patterns.
Power
Your ability to combine force and speed.
LONGITUDINAL TRACKING
Track real improvement
The first session establishes your baseline.
Future sessions allow us to compare your performance against your own previous results, making it possible to see whether your training is actually producing measurable improvements.
We can track changes in:
ACTIONABLE INSIGHTS
From testing to training
Testing is only useful if it changes what you do next.
Backfield uses your results to highlight the physical qualities that deserve the most attention and help guide your next phase of training.
• For one athlete that may mean improving explosive power.
• For another, it may mean developing strength, reactive ability, movement velocity, or mobility.
The goal is simple:
Measure
Capture raw data with Output Sports sensors
Understand
Translate metrics into your Backfield profile
Train
Focus on high-priority development targets
Retest
Benchmark subsequent sessions against your baseline
Improve
Verify true athletic progression with real numbers
