When using Output Sports, you can choose between two velocity-based training options:
AVBT - Angular Velocity-Based Training
VBT - Linear Velocity-Based Training
Both provide valuable insights into performance, but they differ in how and when to use them.
What is AVBT (Angular Velocity-Based Training)?
AVBT tracks angular velocity which is the speed of a limb during movement. This makes it ideal for bodyweight, unilateral, or rotational movements, where tracking linear bar speed isn't possible.
Why use AVBT?
Great entry point to VBT for less experienced athletes
Enables intent-based training in non-loaded exercises
Useful in rehab/return-to-play, e.g. identifying limb asymmetries
Applicable for jump testing, split squats, push-ups, and more

What is VBT (Linear Velocity-Based Training)?
VBT tracks linear velocity which is the straight-line speed of a barbell or implement during a lift. This method is commonly used for loaded strength and power training.
Why use VBT?
Allows for load prescription using velocity zones (e.g. 0.5 m/s for strength)
Supports daily autoregulation based on athlete readiness
Monitors fatigue via velocity drop-off
Used for load-velocity profiling and tracking progress over time

Quick Comparison Table
Feature | AVBT (Angular) | VBT (Linear) |
Velocity type | Angular (°/s) | Linear (m/s) |
Movement type | Bodyweight, single-limb, rotational | Loaded, straight-line barbell movements |
Sensor placement | On limb (e.g. thigh, arm) | On equipment (e.g. barbell, dumbbell) |
Best suited for | Return to play, jumps, split squats | Squats, deadlifts, presses, Olympic lifts |
Use case complexity | Beginner-friendly | Best for trained athletes |
Group training | Slower to scale | Easy to manage |
Which Should I Use?
Goal | Use This Option |
Rehabilitating an athlete post-injury | AVBT |
Coaching youth or beginners | AVBT |
Load-velocity profiling or power development | VBT |
Managing barbell training volume | VBT |
