Article Abstract
Background: While adolescents have specific risk factors for acute and chronic injury, there is a lack of preventive medicine algorithms for this vulnerable group. Shear wave elastography (SWE) is currently mainly used for assessing muscle and tendon stiffness in adult athletes and can diagnose tissue pathologies such as tendinopathy. The aim was to investigate differences in quadriceps tendon and muscle stiffness between adolescent and adult professional soccer players using SWE and identify lateral imbalances in order to improve the knowledge of preventive medicine algorithms for professional adolescent athletes.
Methods: Standardized SWE examinations of both lower limb tendons and muscles (the quadriceps tendon (QT) and the vastus medialis (VM) muscle) in the longitudinal plane and relaxed tendon position were performed in 13 healthy adolescent soccer athletes (13-17 years), and a control group of 19 healthy adult professional soccer athletes (18-29 years).
Results: Adolescent soccer players had lower stiffness values for both the quadriceps tendon (3.11 m/s vs. 3.25 m/s) and the vastus medialis muscle (1.67 m/s vs. 1.71 m/s) than adult athletes. Moreover, QT stiffness in adolescent soccer players was significantly lower on the right side (QT: adult 3.50 m/s (2.73-4.56) vs. adolescent 2.90 m/s (2.61-3.12); = 0.031). Analysis of the lateral differences revealed softer QT and VM tissue on the right side in over two-thirds of adolescent soccer athletes. Over two-thirds of adults had stiffer QT and VM tissue on the right side.
Conclusion: In adolescent soccer players, the stiffness of the QT and VM muscle measured by SWE is lower in the right leg. SWE of the musculoskeletal system may thus become a relevant diagnostic tool to detect early lateral imbalances as a main risk factor for injury and may thus contribute to the prevention of acute and chronic injury prevention in adolescent athletes.

Background: To describe a dynamic ultrasound modified prone Lachman test to assess total anterior/posterior knee displacement. To evaluate the intra- and inter-rater reliability of the ultrasound measurements obtained during the modified prone Lachman test.
Methods: Participants laid prone on an exam table as the trained researcher and assistant performed a Lachman test on both limbs.
Background: Female athletes are underrepresented in sports injury research, especially regarding soccer-related injury patterns in adolescent females. This study analyzes injury trends among high school-aged female soccer players to address injury risks in this population. We hypothesize that soccer-related injuries in high school-aged females most commonly involve the head or lower extremities, with incidence decreasing over time due to improved prevention measures.

Mental health conditions affect many young people in sub-Saharan Africa (SSA), where stigma is high and access to care is limited. Digital tools accessible on basic mobile phones offer a scalable way to promote mental health, but evidence on their effectiveness in SSA is limited. This study evaluated the reach, feasibility, acceptability, and knowledge outcomes of Digital MindSKILLZ, an interactive voice response (IVR) mental health intervention implemented in the Democratic Republic of Congo, Ghana, Nigeria, Rwanda, Uganda, and Zambia.

Background: Adolescence is a critical period of physical, psychological, and social development, during which athletes are particularly vulnerable to stress and injuries. Competitive anxiety has been identified as a psychological factor that may increase injury risk; however, its role among young soccer players remains underexplored.
Objectives: This study aimed to analyse the association between competitive anxiety and injury vulnerability in young male soccer players aged 10 to 15 years.
