Technical Details
- Variable Type: Discrete Metric
- Data Type: Float
- Units: Degrees (°)
- Column Name:
launch_position - Range: 0° to 180°
- Calculation: Sagittal plane (somersault) angle between bat and spine
- Measurement Point: At pelvis velocity initiation (launch event)
- Aggregation: mean
- Precision: 0
- Optimal Direction: Middle — moderate values are optimal
Interpretation
- Higher values: (over 90°) Bat angled downward relative to spine, bat tip is lower
- Lower values: (under 90°) Bat angled upward relative to spine, bat tip is higher and bat is closer to being in line with spine.
- Optimal range: Typically 30-90° for most hitters, preferrably closer to 90°
Use Cases
- Swing analysis and coaching
- Bat path optimization
- Pre-swing position consistency
