Technical Details
- Variable Type: Movement Flag
- Data Type: Integer
- Units: N/A
- Column Name:
cocking_phase_lack_external_rotation - Optimal Direction: Lower is better
- Unknown Value: -1
- Measurement: Cocking Phase Max Shoulder External Rotation
- Threshold: Max shoulder external rotation less than 180°
Description
Cocking phase lack of external rotation is a binary indicator that flags when the dominant shoulder does not reach at least 180° of external rotation (layback) during the cocking phase, which limits the elastic energy available for the acceleration phase.Use Cases
- Layback and shoulder loading assessment
- Injury risk identification
- Mechanics evaluation
