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