Technical Details
- Variable Type: Discrete Metric
- Data Type: Boolean
- Units: True/False
- Column Name:
flying_open - Measurement: Trunk angular velocity peak timing and X-factor at foot contact
- Threshold: Trunk angular velocity peaks before foot contact AND X-factor within 5° of neutral (0°) at foot contact
Description
Flying open is a binary indicator that flags early trunk rotation during the pitch. It occurs when the trunk angular velocity is peaking before foot contact and the X-factor (hip-shoulder separation) is within 5 degrees of 0 at foot contact.Use Cases
- Timing assessment
- Rotation sequencing evaluation
