Description
Trunk lateral tilt at foot contact measures the side-to-side (left/right) tilt of the trunk at the instant of front foot contact during the pitch. This is an indicator of body positon 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.| Population | Optimal Range (25th–75th) | 10th | 25th | 50th | 75th | 90th |
|---|---|---|---|---|---|---|
| Youth | -8 – -2 ° | -11 | -8 | -5 | -2 | 1 |
| High School | -7 – 0 ° | -10 | -7 | -3 | 0 | 8 |
| College | -4 – 4 ° | -8 | -4 | 1 | 4 | 8 |
| Professional | -4 – 11 ° | -10 | -4 | 5 | 11 | 16 |
| Broad (All Levels) | -7 – 3 ° | -10 | -7 | -3 | 3 | 9 |
Use Cases
- Trunk alignment assessment at foot contact
- Posture evaluation
