Context: Volitional preemptive abdominal contraction (VPAC) during dynamic activities may
alter trunk motion, but the role of the core musculature in positioning the trunk during landing …

Objectives To investigate the effects of pelvic and trunk lateral tilt-focused landing
instructions on the knee abduction moment during the single-leg drop vertical jump task …

Background Biomechanical analysis of stop-jump tasks has demonstrated gender
differences during landing and a potential increase in risk of noncontact anterior cruciate …

Purpose The purpose of this study was to examine the effect of changing toe direction on
knee kinetics and kinematics associated with anterior cruciate ligament injury during drop …

Background: Anterior cruciate ligament injuries (ACL) commonly occur during jump landing
and cutting tasks. Attempts to land softly and land with greater knee flexion are associated …

Background: Research has demonstrated that performing a secondary task during a drop
vertical jump (DVJ) may affect landing kinetics and kinematics. Purpose: To examine the …

Background: Frontal plane trunk lean with a side-to-side difference in lower extremity
kinematics during landing increases unilateral knee abduction moment and consequently …

BACKGROUND: Though the first landing of drop vertical jump task is commonly used to
assess biomechanical performance measures that are associated with anterior cruciate …

Background: Impact and lower extremity joint angles during landing are factors that can
increase the risk of anterior cruciate ligament injuries. However, the correlations between …

Study Design Controlled laboratory, cross-sectional, cohort design. Objective To determine if
a sex-specific pattern of lower limb asymmetries is present during a drop vertical jump (DVJ) …
