Available in PDF, EPUB and Kindle. Book excerpt: Background: Anterior cruciate ligament (ACL) injury frequently occurs in female soccer athletes during deceleration movements such as landings. In soccer, landings mostly occur following jumping headers. Little research has been done to determine the mechanics that follow and how they compare to standard drop vertical jumps (DVJ). The purpose of this study was to analyze differences between jumps and landings in kinematics, kinetics, and muscle activation patterns in female soccer athletes to better assess the sport-specific risk for ACL injury. It was hypothesized that more biomechanical tendencies associated with ACL risk factors would emerge from soccer-specific vertical jumps (SSVJ) compared to DVJs and second landings (L2) compared to first landings (L1). Methods: 8 female participants (20.88 ± 1.17 years; 1.68 ± 0.06 m; 58.77 ± 7.65 kg) performed DVJs and SSVJs. Motion capture, force, and electromyography (EMG) data were collected to calculate joint motion, loading, and muscle activation throughout landing phases. Data were analyzed using RM-ANOVA, collapsed across jump (DVJ vs. SSVJ) and landing (L1 vs. L2). Results: Significant findings were revealed in all categories, however, kinematic variables were the most profound results. Significantly higher jump height was achieved in DVJs (p=0.008). SSVJs and L2s produced less peak hip (p=0.03; d=0.817) (p=0.007; d=1.566) and knee 2 (p=0.002; d=0.732) (p=0.002; d=1.476) flexion during landing, respectively. A significant interaction was present for trunk flexion at initial contact (p=0.034). Follow-up tests revealed no significant differences following headers. Discussion: SSVJ-L2s displayed a more erect landing at the hip and knee, a known ACL risk factor, however, it is unclear whether these results are due to trunk movement during heading. Limited results in kinetic and EMG variables may be explained by the difference in jump height achieved, therefore further investigation in a more elite population is required. Additionally, SSVJs may be a good sport-specific screening tool.

Available in PDF, EPUB and Kindle. Book excerpt: Backgrround: Several studies have investigated biomechanical deficits in jump landing; however, these studies are often performed in a laboratory with little distraction to the participant. Injury has been shown to occur during sport-specific distraction where the individual is cognitively loaded during motor performance. Purpose: The purpose of this study was to determine the effect of a cognitive task on jump-landing mechanics. Methods: A dual-task design was used to determine the effects a cognitive dual task on the tuck-jump assessment and peak vertical ground reaction force in 20 participants.

Book Synopsis The Effect of Mid-flight Trunk Motion on Landing Mechanics by : Taylour J. Hinshaw
Download or read book The Effect of Mid-flight Trunk Motion on Landing Mechanics written by Taylour J. Hinshaw and published by . This book was released on 2017 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anterior cruciate ligament (ACL) is a commonly experienced injury that can cause long-term negative health consequences. Previous research has observed increased trunk motion when ACL injuries occur during jump-landing tasks and suggest that trunk perturbation experienced while in the air may be a contributing factor to ACL injuries, however, the cause-effect relationship between trunk motion and ACL loading has not been established. The current researcher quantified the influences that both medial and lateral mid-flight trunk motions on landing biomechanics through center of mass analysis. Results from the current study showed that at initial contact, the upper body moved towards the reaching direction while the pelvis, ipsilateral leg, and contralateral leg moved in the opposite direction for the left and right reaching conditions when compared to the up condition. The ipsilateral leg moved closer to the overall COM and the contralateral leg moved further away, resulting in an asymmetric landing posture. The ipsilateral leg landed earlier for the left and right reaching conditions when compared to the up condition and also experienced a greater amount of vertical ground reaction force putting it at a higher risk for injury. Injury prevention programs should incorporate effective strategies to compensate for trunk motion experienced during the mid-flight of a jump.
Book Synopsis Neuromuscular Control and Movement Variability in Adolescent Female Soccer Athletes During Simulated Soccer Jump Header Landing Task by : Emily Elizabeth Grammer
Download or read book Neuromuscular Control and Movement Variability in Adolescent Female Soccer Athletes During Simulated Soccer Jump Header Landing Task written by Emily Elizabeth Grammer and published by . This book was released on 2019 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lateral ankle sprain (LAS) is the most common orthopedic injury in athletics and is the result of simultaneous excessive inversion of the ankle and supination of the foot. Following initial LAS, degenerative changes have been found in over 70% of participants for extended periods of time. With the aforementioned degenerative changes typically come alterations in movement patterns, muscle activation patterns, and arthrokinematics. The current study aimed to investigate the effects of LAS history on neuromuscular control during a soccer specific jump-landing task and to illustrate the impact of limb (injured vs. non-injured) on neuromuscular control during a soccer specific jump-landing task in female adolescent athletes (n = 14, age = 16 ± 1.0 yr). A control group (n = 7) and a group designated as the "ankle sprain" group (n = 7) were used. The injured ankles in the ankle sprain group and the dominant limbs of the control group were labeled "affected," while the uninjured limbs of the ankle sprain group and the non-dominant limbs of the control group were labeled "unaffected." Electromyography (EMG) sensors were placed on 6 lower-limb muscles of each participant bilaterally, totaling 12 sensors per participant -- Lateral Gastrocnemius (LG), Peroneus Longus (PL), Tibialis Anterior (TA), Vastus Lateralis (VL), Vastus Medialis (VM), and Biceps Femoris (BF). Each participant completed a 5-minute low-to-moderate intensity warm-up on a cycler ergometer, then completed 10 soccer-header jump-landing trials. There were no significant limb by group interactions (p > 0.05) or group main effects (p > 0.05) found in the current study. Pre-landing data showed significant limb main effects for the vi standard deviation (SD) of the unaffected PL (p = 0.017) and the affected VL (p = 0.048). Furthermore, significant limb main effects were discovered for the COV of pre-landing muscle activation for the PL (p = 0.043), LG (p = 0.049), and VL (p = 0.048). During the post-landing period, significant limb main effects were recorded for the average activation (p = 0.001) and SD (p = 0.003) of the PL and the COV of the VL (p = 0.038). Reduced activation of the nondominant limbs illustrated increased neuromuscular control in the distal musculature (PL), while the proximal musculature (VL) demonstrated reduced neuromuscular control on the unaffected limbs. The current study discovered that limb dominance was a more prominent factor in altered lower-leg neuromuscular control compared to ankle injury history. Limb differences were most likely the result of the sport-specific demands placed on the dominant and non-dominant limbs during soccer, which elicited increased muscular responses of the non-dominant limb during jump-landing tasks.

Book Synopsis The Effects of Ankle Taping and Ankle Bracing on Vertical Jump Performance in Healthy Elite Female Soccer Players by : Laura M. Stroup
Download or read book The Effects of Ankle Taping and Ankle Bracing on Vertical Jump Performance in Healthy Elite Female Soccer Players written by Laura M. Stroup and published by . This book was released on 2000 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ankle taped, braced, and bare. Therefore, each subject performed eighteen total test jumps for this study. Performance of single-leg vertical jumps initiated from various stride run-up lengths was not significantly affected by ankle taping or bracing. This study failed to show a statistical significance in decreased vertical jump heights in subjects with taped and braced ankles when compared to vertical jump heights in subjects with bare ankles. Ankle taping and bracing are widely accepted practices in sports medicine for injury rehabilitation and prevention. Taping and bracing a sprained ankle allowed athletes to return to sport quickly and safely after sustaining an injury. Researchers found both taping and bracing a sprained ankle reduced the occurrence of reinjury. Athletes often will not compromise performance for safety and injury prevention. Therefore, the chosen prosthetics must not hinder performance as they offer protection. Otherwise, athletes will not be compliant.
