Description
Pelvis deceleration time measures the duration of the pelvis deceleration phase from peak angular velocity to the end of rotation, indicating the control and efficiency of lower body mechanics.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 |
