Repeatability of Ground Reaction Force during Jump-Landing in Volleyball Players with Functional Ankle Instability
Background and Aims: The accurate mechanisms of ankle instability cannot be assessed in the absence of reliable knowledge about ground reaction force (GRF) variables. The purpose of this study was to evaluate the test-retest reliability of GRF variables during forward and lateral jump-landing in volleyball players with functional ankle instability (FAI). Methods: Eighteen professional volle...
متن کاملRelationship between kinematic parameters of the lower limb and maximum ground reaction force during jumping and one-legged landing
Background: Anterior cruciate ligament injury is one of the most common injuries of the knee joint and prevention of this injury is of great importance(1). Considering that ground reaction forces are one of the load factors on the anterior cruciate ligament, Despite much research in this field to prevent ACL injury, the prevalence of this injury is still high(2). For example, previous studies h...
متن کاملNumber of trials necessary to achieve performance stability of selected ground reaction force variables during landing.
The objectives were to determine the number of trials necessary to achieve performance stability of selected ground reaction force (GRF) variables during landing and to compare two methods of determining stability. Ten subjects divided into two groups each completed a minimum of 20 drop or step-off landings from 0.60 or 0.61 m onto a force platform (1000 Hz). Five vertical GRF variables (first ...
متن کاملThe effects of line of sight on ground reaction force and pressure during landing
“Keep your eye on the ball,” is an old sports adage. This is especially true in sports like volleyball, tennis, American football, and basketball. Among these sports, basketball is one of the few sports where airborne athletes cannot visually reestablish their relationship to the ground because they are focused on the ball. This typically happens when athletes are attempting to rebound a missed...
متن کاملGround Reaction Force and Valgus Knee Loading during Landing after a Block in Female Volleyball Players
A non-contact anterior cruciate ligament (ACL) injury is both a serious and very common problem in volleyball. The aim of the study was to determine the association between stick, step-back, and run-back landings after a block and select risk factors of ACL injuries for female professional volleyball players. The research sample involved fourteen female professional volleyball players. Two forc...
