Virtual environments with real-time feedback can simulate extrinsic goals that mimic real life conditions. The purpose was to compare jump performance and biomechanics with a physical overhead goal (POG) and with a virtual overhead goal (VOG). Fourteen female subjects participated (age: 18.8±1.1 years, height: 163.2±8.1 cm, weight 63.0±7.9 kg). Sag...
Article
Context: Risk of ACL injuries in young female athletes increases with age, appearing to peak during maturation. Changes in hip muscle strength and range of motion (ROM) during this time may contribute to altered dynamic movement patterns that are known to increase risk of ACL injuries. Understanding the longitudinal changes in hip strength and ROM...

Background: Double-leg forward or drop-jump landing activities are typically used to screen for high-risk movement strategies and to determine the success of neuromuscular injury prevention programs. However, research suggests that these tasks that occur primarily in the sagittal plane may not adequately represent the lower extremity biomechanics...

Turf toe, first metatarsophalangeal joint (MTPJ) sprain, is a debilitating injury in football players that is likely the result of excessive dorsiflexion of the hallux. Understanding in-cleat motion of the MTPJ with increased magnitudes of midsole stiffness may help to identify footwear modifications for treatment and injury risk. The purpose was t...

Deficits in proximal hip strength or neuromuscular control may lead to dynamic lower extremity valgus. Measures of dynamic lower extremity valgus have been previously shown to relate to increased risk of several knee pathologies, specifically anterior cruciate ligament ruptures and patellofemoral pain. Therefore, hip-focused interventions have gain...

... The method was used in two studies to classify players by pubertal status. Among 34 players (13.3 ± 1.5 years), nine were classified as pubertal (88-94%) and 25 as post-pubertal (>94%); the ages of players in each group were not indicated [55]. In the other study, players aged 9-17 years were classified as pre-pubertal (<87%, n = 17, 10.3 ± 0.6 years), pubertal (87-94%, n = 32, 11.9 ± 0.8 years) or post-pubertal (>94%, n = 90, 14.6 ± 1.6 years) [56]. ...
... 17 Using different methods will manifest as different limbs being classified as the dominant and non-dominant. Multiple studies have shown that individuals vary their preferred limb across different lower-limb tasks, [18][19][20] while Mulrey et al. (2018) 19 demonstrated that the limb classified as the dominant differed within the similar hopping tasks of vertical jump height and horizontal hop distance. ...
... Currently, whole body dual-energy x-ray absorptiometry (DXA) measurements are used as a method to assess an individual's risk of stress fracture injury [5]. lower bone mineral density (BMD), bone mineral content (BMC) and reduced bone structural properties have been associated with stress fracture risk in some athletic population (cricketers (lumbar spine BMD, [6]), runners (tibial strength, [7]; hip BMD, [8]), triathletes (tibial cortex; [9]) and female athletes (trabecular BMD; [10]), but not in others (endurance athletes (triathletes and runners-whole body, lumbar spine and hip) [11] and runners (whole body, lumbar spine, hip, radius) [12][13]. ...
... Extensive research has been carried out to analyse which parameters must be improved to increase vertical jump height (Linthorne, 2001). One of these parameters is lower-extremity stiffness, which is frequently associated with athletic performance and lower-extremity injury risk (Goodwin et al., 2019;Serpell et al., 2012;Waxman et al., 2018). Stiffness can be defined as a body part's resistance to a change in its length caused by a force applied to it (Brughelli and Cronin, 2008;McMahon and Cheng, 1990). ...
... Stability during walking In this study, the insole plantar pressure distribution measurement system (Novel Pedar, Germany) will be used to determine postural stability during the walking. Each insole contains 99 pressure sensors, which help to collect plantar pressure accurately and sensitively and to calculate the changes in COP in different tasks [31]. In advance of the testing, the pressure insole that fits the size of the participant's shoe will be inserted into the left and right shoe and sampled at 100 Hz. ...
... Literature results have shown that medial SLHTs report higher lower extremity asymmetry when compared with forward SLHTs. [21][22][23]51,52] Similar to the results of our study, Dingenen et al. (2019) found mean LSI as 100,65% in a study they examined asymmetry rates in healthy athletes on whom they applied SL, THD, MSTH and MRH tests. [20] Although studies conducted on athletes from different branches showed different results in jump distance, LSI values were found to be within normal ranges (90-100%). ...
... BSPs can serve as input data for engineering prosthetics [1,2], for ergonomic design [3], and are required for inverse dynamics [4]. Although 'generic' datasets that are composed of measurements from a range of humans can be used for approximating BSPs of people, direct in vivo participant-specific estimates provide the highest level of accuracy [5]. Unfortunately, direct approaches to estimate BSPs can be cumbersome and expensive. ...
... reduced range of motion) hip and knee strategy is effective for performance by reducing GCT and potentially permitting more effective reactive strength and stretch shortening cycle utilisation [53,121,122], thus facilitating more effective force transmission due to the rapid transition from braking to push-off. However, stiffer and extended braking strategies ineffectively dissipates forces and energy [80,[123][124][125][126][127], increases loading rates [128], and may increase anterior tibial [74,[83][84][85] and knee abductor loading [128][129][130][131]. Soft weight acceptance strategies are often coached in injury mitigation programmes to reduce impact GRFs and knee joint loads [73,[132][133][134]; however, practitioners must consider the conflict between performance and injury risk when manipulating such sagittal plane joint kinematics during cutting. ...
... Lower extremity biomechanics were collected during a bilateral drop vertical jump (DVJ) and a single-leg unanticipated cutting task (CUT) [14]. Participants were instrumented with 43 retroreflective markers placed on the sternum, sacrum, left posterior superior iliac spine, C7, 3 points on the upper back (via a thin backpack), and bilaterally on the shoulder, upper arm, elbow, wrist, anterior superior iliac spine, greater trochanter, midthigh, medial and lateral knee joint line, tibial tubercle, midshank, distal shank, medial and lateral malleolus, and to the foot at the heel, dorsal surface of the lateral midfoot, lateral rear foot and 2nd met via doublesided tape [15]. ...
... At the same time, they analyze joint kinetics and kinematics to identify biomechanical performance in terms of postural adjustment and center of mass shifting to maintain balance [2]. Jumping performance is closely related to the jumping technique that can be improved through different strategies [3]- [6]. It is essential to mention that an increased jump height will also increase the landing height, that which requires a greater mechanical demand during the landing phase on the hip, knee, and ankle joints [7]. ...
