    Sport specialization is a growing trend in youth athletes and may contribute to increased injury risk. The neuromuscular deficits that often manifest during maturation in young, female athletes may be exacerbated in athletes who specialize in a single sport. The purpose of this study was to investigate if sport specialization is associated with increased lower extremity biomechanical deficits pre- to post-puberty in adolescent female athletes. Seventy-nine sport-specialized female adolescent (Mean ± SD age = 13.4 ± 1.8 years) basketball, soccer, and volleyball athletes were identified and matched with seventy-nine multi-sport (soccer, basketball, and volleyball) female athletes from a database of 1,116 female adolescent basketball, soccer, and volleyball athletes who were enrolled in one of two large prospective, longitudinal studies. The athletes were assessed over two visits (Mean ± SD time = 724.5 ± 388.7 days) in which they were classified as pre-pubertal and post-pubertal, respectively. Separate 2 × 2 analyses of covariance were used to compare sport-specialized and multi-sport groups and dominant/non-dominant limbs with respect to pubertal changes in peak knee sagittal, frontal, and transverse plane joint angular measures and moments of force recorded while performing a drop vertical jump task. The sport-specialized group were found to exhibit significantly larger post-pubertal increases in peak knee abduction angle (p = 0.005) and knee abduction moment (p = 0.006), as well as a smaller increase in peak knee extensor moment (p = 0.032) during landing when compared to the multi-sport group. These biomechanical changes are indicative of potentially compromised neuromuscular control that may increase injury risk pre- to post-puberty in sport-specialized female athletes. Consideration of maturation status may be an important factor in assessing the injury risk profiles of adolescent athletes who specialize in sport

    El aumento de la participación de los niños y jóvenes en las competiciones deportivas ha llevado a un incremento paralelo de la incidencia de lesiones por sobre uso en este grupo poblacional. Las observaciones empíricas de que los niños y adolescentes de hoy en día realizan menor nivel de actividad física respecto de sus padres y abuelos contrasta con el incremento progresivo del estrés específico causado por las actividades deportivas actuales. Los niños de hoy han mostrado tener menor capacidad de recuperación y un sistema musculo esquelético más débil y por lo tanto con mayor riesgo de dañarse cuando se les somete a la realización repetida de actividades especificas intensas. Existen diferencias físicas y fisiológicas entre niños y indolentes que hace que los primeros sean más susceptibles de lesionarse. Muchas factores contribuyen a la existencia de estas diferencias, incluido el proceso de crecimiento en sí mismo, la vulnerabilidad del cartílago de crecimiento, las deficiencias de fuerza y insuficiente la capacidad para realizar habilidades motoras complejas. Durante los periodos de rápido crecimiento, los desequilibrios en la fuerza muscular y la flexibilidad predisponen a los deportistas jóvenes a sufrir lesiones de gran importancia que puedan determinar un déficit motor que permanezca durante toda la vida. El objetivo de este artículo es revisar las lesiones más habituales que el médico clínico observa en niños y jóvenes deportistas. Un equipo multidisciplinario es necesario para atender las necesidades de esta población específica. El futuro de la medicina deportiva pediátrica es la prevención de lesiones siendo la educación para realizar una intervención temprana la clave para alcanzar el éxito.The dramatic rise in organized sports participation by the young athlete has been met with an increase in significant acute and overuse injuries. The empiric observation that children and adolescents in our modern society are confronted with fewer physical stresses than their parents or grandparents is contrasted with the increasing specificity of stresses that are placed on them during current sports and athletic training activities. Children today may have less resilient and weaker muscle-tendon units and therefore face double jeopardy when confronted with specific, intense physical challenges that apply repetitive stress to unprepared tissues. There are physical and physiological differences between children and adults that may cause children to be more vulnerable to injury. Many factors contribute to these differences, including the growth process itself, vulnerability of growth cartilage to stresses, and strength and complex motor skill deficits. During times of rapid growth muscle strength and flexibility imbalances predispose the young athlete to injuries that are significant and possibly contribute to lifelong deficits. It is the objective of this lecture to review common pediatric sports injuries presenting to the clinician. A multidisciplinary team is required to address the unique needs of this expanding population. The future of pediatric sports medicine is injury prevention. Education with regard to early intervention is the key to success.Sin financiaciónNo data 201

    Infographic. Ten naked truths about the pelvic floor in athletes

    No full text
    Pelvic floor dysfunction (PFD) is an umbrella term including a myriad of conditions including urinary and anal incontinence, pelvic organ prolapse, pelvic pain and sexual dysfunction. High impact sports have been linked with an increased risk of developing PFD. For instance, up to 76% of female volleyball players reported urinary symptoms. Despite the widespread occurrence and consequences of PFD, it remains under reported by athletes.1 2 Misinformation, misperceptions and miseducation about PFD for both clinicians and athletes can adversely impact an athlete’s health, care, training and performance

    Top 10 Research Questions Related to Exercise Deficit Disorder (EDD) in Youth

    No full text
    Exercise deficit disorder (EDD) is a pediatric medical condition characterized by reduced levels of moderate-to-vigorous physical activity (MVPA) that are below current recommendations and inconsistent with positive health outcomes. At present, a majority of children and adolescents meet the diagnostic criteria for EDD because they are not accumulating minimum thresholds of daily MVPA. The purpose of this article is to highlight 10 important research questions related to EDD in youth. The critical research needs to better define the clinical spectrum of EDD to include an assessment of physical activity behaviors to determine the age or stage of maturation at which EDD first emerges; an examination of the kinesiogenesis of movement skills and physical abilities; and an evaluation of lifestyle factors that can influence the MVPA trajectory in youth. Research questions about interventions and policies to treat EDD include evaluating the education and training of health care providers on the importance of exercise medicine; determining the effectiveness of strategies to identify and treat youth with EDD in clinical practice; developing sensitive, specific, and cost-effective methods to diagnose youth with EDD; and assessing methods to promote health care reimbursement for the treatment of this condition. Without future research to optimize identification, treatment, and management strategies for youth with EDD, new health care concerns with significant biomedical, psychosocial, economic, and political ramifications will continue to emerge
