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
