Technical Details

  • Variable Type: Discrete Metric
  • Data Type: Float
  • Units: °
  • Column Name: trunk_angle_to_plate_coil
  • Aggregation: mean
  • Precision: 0
  • Measurement: Maximum trunk rotation away from home plate prior to delivery
  • Reference: 0° = facing home plate
  • Typical Range: 112 – 132 °
  • Optimal Direction: Higher is better

Description

Trunk angle to plate coil measures the maximum trunk rotation angle away from home plate prior to delivery, where facing home plate is 0 degrees. This represents the coil or loading phase of the trunk.

Normative Ranges

Percentile distributions by competition level from the 2026 Q1 dataset; the optimal range spans the 75th–90th percentiles.

Use Cases

  • Trunk loading assessment
  • Rotation analysis
