Description
Trunk lateral tilt at ball release measures the side-to-side (left/right) tilt of the trunk at the instant of ball release during the pitch. This is an indicator of body position at a critical point in time, useful for measuring proper positioning and consistency.Normative Ranges
Percentile distributions by competition level from the 2026 Q1 dataset; the optimal range spans the 25th–75th percentiles.Use Cases
- Trunk alignment assessment at release
- Posture evaluation
