Influence of increasing knee flexion angle on knee-ankle varus stress during single-leg jump landing.
J Taibah Univ Med Sci
December 2017
Article Synopsis
- * Data was collected from 15 male players using a 3D motion analysis system, measuring various angles and forces during a jump after running a set distance.
- * Results showed a significant correlation where greater knee flexion led to increased lateral pressure displacement, ankle varus moment, and knee varus angle, suggesting that understanding these relationships can aid in developing better training protocols for injury prevention.
Objectives: The relationship between knee kinematics and knee-ankle kinetics during the landing phase of single leg jumping has been widely studied to identify proper strategies for preventing non-contact ACL injury. However, there is a lack of study on knee-ankle kinetics at peak knee flexion angle during jumping from running. Hence, the purpose of this study is to establish the relationship between peak knee flexion angle, knee extension moment, ankle plantar flexion moment and ground reaction force in handball players in order to protect ACL from excessive stress during single leg jumping.
