Technical Details

  • Data Type: Integer
  • Units: Frame number
  • Column Name: wrist_movement_initiation_frame
  • Detection Method: Last local minimum before peak wrist angular velocity
  • Phase: Final acceleration phase

​
Description

Wrist initiation marks the beginning of the final acceleration phase when the wrists start moving to generate bat speed. This event is crucial for understanding the complete kinetic chain sequence.

​
Use Cases

  • Final acceleration analysis
  • Kinetic chain evaluation
  • Bat speed generation assessment
  • Swing sequence timing
