Skip to main contentTechnical Details
- Variable Type: Discrete Metric
- Data Type: Float
- Units: ratio
- Column Name:
pelvis_to_trunk_velocity_speedup
- Calculation: Peak trunk velocity / Peak pelvis velocity
- Optimal Range: 1.5+
Description
Pelvis to trunk speed up measures the multiplication factor of velocity increase from the pelvis to the trunk peak angular velocities.
This metric broadly indicates the efficiency of power transfer from the lower body to the core.
Use Cases
- Power transfer analysis
- Kinetic chain efficiency
