Learned Biomechanics Through Feedback: Investigating the Transferability of a Jump Landing Task to a Cutting
… cruciate ligament (ACL) injury. Currently, jumplanding feedback interventions have demonstrated the ability to alter movements that increase the risk of ACL injury during landing. Unfortunately, it remains unknown if jump-landing interventions, which demonstrate the ability to alter …

An investigation to determine horse-hoof slippage following jump landing on two different equine arena surfaces
… to be a common cause of soft-tissue injury. Show-jumpers are reported to require a small amount of slide as they land; this suggests the amount of slide has a narrow safety margin in order to prevent injury. The aim of the study was to compare hoof slide on two different artificial surfaces and …

The role of surface condition in athletic performance
… unstable surfaces during movements like vertical jumps. Of note, under unstable conditions, trunk muscles seem to have a stabilizing function during exercise to facilitate the transfer of torques and angular momentum between the lower and upper extremities. The present thesis addresses the acute …

An investigation of the Landing Error Scoring System and clinically assessable sport-related injury risk factors
… relies on identifying individuals at risk. The Landing Error Scoring System (LESS) is a clinical injury risk screening tool suitable for large-scale screening without expensive equipment. However, psychometric properties, influencing factors, and differences in methodological procedures reported …

The biomechanical demands of snowboard landings in training with elite freestyle snowboard athletes
… kinematic and muscular demands relative to jump landing actions has not been investigated with elite freestyle athletes. Data were collected from athletes of the Great Britain Park and Pipe team during an official team training session, conducted on an artificial landing slope. Five athletes …

Hindfoot and forefoot kinematic differences among individuals with and without Functional Ankle Instability
… data during two common tasks (walking gait and jump landing) among three groups: individuals with FAI, healthy controls and copers. Design: 3-group observational cross-sectional study. Participants: Participants included 23 individuals with a history of ≥ 1 ankle sprain and at least 2 episodes …

The Influence of Heel Height on Sagittal Plane Knee Kinematics during Landing Tasks in Recreationally Active Collegiate Females
… would alter sagittal plane knee kinematics when landing from jumping maneuvers. The hypothesis was that increased heel height would increase knee flexion at initial contact (KAIC), increase the peak knee flexion angle (KAPeak), and slow the rate of knee excursion (RKE). Fifty recreationally …

Effects of Ankle Support on Time To Stabilization of Subjects with Stable Ankles
… of each subject performing a single leg jump-landing with ankle tape, ankle brace, combination of the two, and control (no tape or brace) conditions. Dynamic stability was assessed with time to stabilization force plate measure. Significant plane by ankle tape interaction (p=0.045) was …

Influence of physical training on knee valgus motion and physical performance abilities among adole[s]cent female basketball players
… (including a warm-up and plyometric, jump, flexibility, and strength training) would decrease valgus motion at the knee joint upon impact of a jump landing task. In addition, another aim of the investigation was to determine if the training routine would enhance physical performance …

Match demands, players´ Characteristics and neuromuscular performance across the season in elite futsal players.
… in the eccentric metrics of the countermovement jump (CMJ). Virtually all strength and conditioning coaches report monitoring training load, most of them through the use of subjective tools, utilize the neuromuscular and strength measurements to evaluate performance and monitor fatigue, and …

Hip Abductor Strength and Hip External Rotator Strength Effects on Medial Knee Displacement in Post Pubescent Females
… and MKD was assessed during a standardized jump-landing task using three-dimensional motion analysis. Participants were instructed to jump off a box, land, and immediately jump upwards for maximal height. Separate correlations were conducted to evaluate the relationship between hip ABD …

Does Psychological Readiness Affect Jump Biomechanics Across the Continuum of Care Following Anterior Cruciate Ligament Reconstruction?
… psychological readiness to return to sport on jump–landing biomechanics after anterior cruciate ligament reconstruction (ACLR) at the time of return to sport testing and 6 weeks after returning to sport. The first aim of the study was to examine whether the level of psychological readiness …
