Forward kinematic sequence

​
Technical Details

  • Variable Type: Discrete Metric
  • Data Type: Categorical / Array
  • Units: N/A
  • Column Name: forward_kinematic_sequence
  • Measurement: Order in which segments reach peak forward angular velocity

​
Description

Kinematic sequence describes the order in which the torso, upper arm, and forearm reach their peak forward angular velocities during the serve. The optimal sequence is proximal-to-distal: torso → upper arm → forearm, supporting efficient energy transfer to the racket. Derived from Peak Torso, Peak Upper Arm, and Peak Forearm forward angular velocities; time-series versions are in Forward Angular Velocity Time Series.

Use Cases

  • Technique quality and sequencing
  • Comparison with optimal sequence (torso-upper_arm-forearm)
  • Coaching and training feedback
