Technical Details
- Variable Type: Discrete Metric
- Data Type: Float
- Units: ratio
- Column Name:
average_arm_circle_radius - Aggregation: mean
- Precision: 2
- Calculation: Average shoulder-to-wrist distance divided by (upper arm length + forearm length)
- Timing: Between drive start and release events
- Optimal Direction: Higher is better
Description
Average arm circle radius measures how extended the throwing arm stays during the windmill arm circle, calculated as the average shoulder-to-wrist distance (normalized by arm segment length) between drive start and release. Values closer to 1 indicate a fully extended arm circle.Use Cases
- Arm circle consistency assessment
- Mechanics evaluation
