Dataset supporting the study: Fourfold faster knee valgus velocity during single-leg landing compared with countermovement jump

ASSOCIATED MANUSCRIPTThis repository contains the dataset and statistical analysis outputs supporting the findings of the following research manuscript:Fésüs Á. et al. (2026). Evidence for fourfold faster knee valgus velocity during single-leg landing compared with countermovement jump: a novel approach to injury risk assessmentDATA DESCRIPTIONThis repository contains the processed biomechanical dataset and statistical analysis outputs used in a study investigating knee valgus kinematics during single-leg landing (SLL) and single-leg countermovement jump (SL-CMJ).The dataset includes participant-level aggregated variables derived from biomechanical measurements and used directly for statistical analyses reported in the associated manuscript.FILES INCLUDED1.
