Technical Details
- Variable Type: Discrete Metric
- Data Type: Float
- Units: degrees/second (°/s)
- Column Name:
pelvis_peak_twist_angular_velocity - Measurement: Peak twist (transverse plane, like a tornado) angular velocity of the pelvis
Description
Peak pelvis twist angular velocity is the maximum twisting angular velocity of the pelvis in the transverse plane (like a tornado). It is the most proximal segment in the Twist Kinematic Sequence (pelvis-torso-upper_arm), reflecting lower-body contribution to the kinetic chain.Use Cases
- Twist kinematic sequence and energy transfer
- Lower-body contribution to serve
- Comparison with peak torso and upper arm twist velocities
