Athletic children are prone to overuse injuries, especially at the heel and knee. Since footwear is an extrinsic factor of lower limb injury risk, the aim of this study was to assess the influence of shoe aging on children running biomechanics. Fourteen children active in sports participated in a laboratory biomechanical evaluation. A new pair of shoes was provided to each participant at an inclusion visit. Four months later, the participants performed a running task and their kinematics and kinetics were assessed both with their used shoes and with a new pair of shoes identical to the first...

BACKGROUND: ACL injury prevention programs are less successful in female basketball players than in soccer players. Previous authors have identified anthropometric and biomechanical differences between the athletes and different sport-specific demands, including a higher frequency of frontal plane activities in basketball. Current injury risk screening and preventive training practices do not place a strong emphasis on frontal plane activities. The medial and lateral triple hop for distance tests may be beneficial for use in the basketball population...

Shoulder injuries in overhead throwing athletes are very common. Throwing volume and mechanical forces that are placed on the glenohumeral joint and associated soft tissue structures are contributors. Poor biomechanics and weak links in the kinetic chain place this athletic population at increased risk for shoulder injuries. Common biomechanical deficiencies in overhead throwing athletes typically involve poor sequential timing of muscle activity and insufficient coordination also presented in shoulder elevation and other functional tasks...

Due to growing concern on brain injury in sport, and the role that helmets could play in preventing brain injury caused by impact, biomechanics researchers and helmet certification organizations are discussing how helmet assessment methods might change to assess helmets based on impact parameters relevant to brain injury. To understand the relationship between kinematic measures and brain strain, we completed hundreds of impacts using a 50th percentile Hybrid III head-neck wearing an ice hockey helmet and input three-dimensional impact kinematics to a finite element brain model called the Simulated Injury Monitor (SIMon) (n = 267)...

BACKGROUND: Reinjury rates after anterior cruciate ligament reconstruction (ACLR) are highest among young athletes, who consequently suffer from low rates of return to play. Historically, quantitative measures have been used to determine readiness to return to sport; however, they do not assess modifiable risk factors related to the quality of movement. PURPOSE: To determine the effectiveness of a criteria-based rehabilitation progression and return-to-sport criteria on efficient return to activity and prevention of second injury in young athletes post-ACLR...

Stress fractures are common overuse injuries in athletes, especially in long-distance runner, jumping sports and gymnastics in female athletes. The pathology of stress fracture mainly includes repeated biomechanical loading, which leads to bone micro-damage and failure of bone structure. Female athlete triad(FAT), which includes low energy availability with or without an eating disorder, functional hypothalamic amenorrhea, and osteoporosis, is a serious healthcare concern in female athletes. For prevention and treatment of stress fracture, management of biomechanical factors modifying the load applied to a bone is important, and especially in female athletes, management for FAT is one of the important factors...

Impact loading in athletes participating in various sports has been positively associated with increased bone mineral density (BMD), but this has not been investigated in elite Kenyan runners. Body composition and site-specific BMD measures quantified with dual x-ray absorptiometry were measured in 15 elite male Kenyan runners and 23 apparently healthy South African males of different ethnicities. Training load and biomechanical variables associated with impact loading, such as joint stiffness, were determined in the elite Kenyan runners...

Side-to-side differences of lower extremities may influence the likelihood of injury. Moreover, adding the complexity of jump-landing direction would help to explain lower extremity control during sport activities. The aim was to determine the effects of limb dominance and jump-landing direction on lower extremity biomechanics. Nineteen female volleyball athletes participated. Both dominant limbs (DLs) and non-dominant limbs (NLs) were examined in single-leg jump-landing tests in four directions, including forward (0°), diagonal (30° and 60°), and lateral (90°) directions...

INTRODUCTION: Several studies have dealt with the issue of professional risk factors and onset of knee osteoarthritis (OA). In particular, occupational epidemiological studies have provided evidence that activities resulting in biomechanical overload may be linked with an increased risk of knee OA - also among farmers. To our knowledge, no cases of knee OA among chestnut farmers have been reported in the literature. CASE REPORT: We report the case of a 70-year-old Caucasian male who has worked for more than 50 years on a chestnut farm...

Alendronate regulates the activity of osteoclasts and healing of osteoporosis. This study investigated the effect of alendronate on bone healing and changes in the levels of cytokines. Bilateral ovaries of 10 adult female rabbits were removed surgically in aseptic condition to establish the animal model of osteoporosis. Five rabbits in group A were treated with alendronate (1.15 mg·kg(-1)·week(-1)) once a week by a stomach tube, whereas the remaining 5 in group B were treated with physiological saline. The success of the animal model establishment and the efficacy of alendronate treatment were evaluated by the sports ability score and the Basso, Beattie, and Bresnahan (BBB) score; the healing degree of osteoporosis was determined by X-ray analysis and measurement of biomechanical properties; the changes in the levels of related cytokines were measured by enzyme-linked immunosorbent assay (ELISA) and immunohistochemical staining...
