Summary: This study found asymmetry between lower extremities during landing and takeoff phases in adolescent athletes following ACL reconstruction. While jump height was related to power generation integrals during takeoff, it did not affect the asymmetry of power generation.

Summary: This study found a significant correlation between ankle dorsiflexion range of motion (DF-ROM) and landing errors, indicating that ankle DF-ROM can be used as a valuable measure to assess landing posture. This could help identify the cause of faulty motion in real-world sport-specific tasks.

Summary: In this study, the correlation between LESS score and knee kinematics during jump-landing task was examined. The results showed significant correlations between LESS score and knee valgus and internal tibial rotation. This suggests that LESS can be an effective measure to identify risky motion patterns that may increase the likelihood of ACL injuries.

Summary: The study found that core stability is related to knee joint movement during DJ landing and knee injury risk factors. Core stability parameters like sit-ups and single-leg stance time showed significant relationships with knee joint motion parameters. Therefore, improving core stability through comprehensive training can effectively prevent knee injuries.

Summary: The study aimed to explore the differences and correlations in ACL loading variables and bilateral asymmetries among injured and uninjured legs as well as different phases of squats and countermovement jumps (CMJ) in collegiate athletes after ACL reconstruction. The results showed that squats had the largest knee/hip flexion angles, while CMJ had the smallest angles during the landing phase. The uninjured leg had higher VGRF and KEM than the injured leg in CMJ. Kinetic asymmetries were smaller in squats but larger in the jumping and landing phases of CMJ. There were significant correlations between KEM asymmetries in CMJ and squats. Kinetic asymmetries persisted in CMJ but symmetry was achieved in squats.

Summary: This study examined the neuromuscular control-related risk factors for ACL injury in badminton players. It found that female players exhibited greater knee valgus angle and muscle activity during the pre-landing phase. These findings suggest that female players may have inadequate neuromuscular control strategies, which could increase the risk of ACL injury.

Summary: Comparisons were made between the overall LESS scores, risk categorisation, specific LESS errors, and double-leg jump-landing jump heights in overhead goal and no goal conditions. The findings suggest that adding an overhead goal in LESS can enhance sport specificity and improve vertical jump performance without significant changes in landing errors and injury-risk categorisation.

Summary: This study aimed to explore the impact of single-legged landing kinematics on the risk of ACL injury. Evaluating the pre-impact kinematics of 33 healthy young female handball players and conducting a two-year follow-up, it was found that the second major kinematic component and minor components accurately discriminated injured and non-injured legs. These kinematic components also significantly affected the knee loading patterns, possibly explaining the future ACL injury risks in female athletes.

Summary: The study aimed to assess the effectiveness of the Safe Landing (SL) programme on improving movement quality in football players. The results showed significant improvements in movement quality for the SL group, while the control group remained unchanged. Additionally, the SL group maintained performance in change of direction tasks, while the control group moderately decreased performance.

Summary: Rates of ACL rupture in young people, particularly females, have increased significantly over the past two decades. Wearing athletic shoes, either low- or high-support, can effectively reduce ACL loads during specific tasks, potentially lowering the risk of ACL injury in sports and recreational activities.

Summary: Recent research suggests that distance running stride-to-stride variability is related to performance and injury. This study examined the sagittal plane joint angles to assess stride-to-stride variability among lower body joints. The results showed significant differences among the joints, with knee swing being the most variable condition. Strong correlations were found between stance and swing variability for all three joints, and moderate to strong correlations were observed among the joints. This study contributes to a better understanding of the joints and phases that contribute most to variability in the overall stride, and suggests that runners have a similar overall stride-to-stride variability pattern across joints and phases.

Summary: This study investigated the association between various medical diagnoses and firearm and nonfirearm suicide. The results showed that behavioral health diagnoses were more strongly associated with nonfirearm suicide in men, while the association for firearm-related suicide was weaker in men compared to women. These findings highlight the differences in associations between different genders and suicide means.

Summary: This study uses survival models to analyze data from trials of substance use treatment programs. The results show that buprenorphine-naloxone is superior to extended-release naltrexone in terms of efficacy outcomes, and extended-release naltrexone has a higher risk of overdose during the study treatment phase.

Summary: This study examined the association between sensation-seeking and a student-athlete's concussion-related knowledge, attitudes, perceived social norms, and care-seeking/disclosure behaviors.
Higher sensation-seeking was significantly associated with less favorable concussion attitudes, less favorable perceived social norms surrounding concussion, and continuing to play while experiencing concussion symptoms.
Therefore, athlete with increased sensation-seeking may be at risk for failing to disclose a concussion, decreasing athlete safety and resulting in less optimal care post-injury.

Summary: Youth sport specialization may increase the risk of negative impacts on physical and psychological health. There is broad representation of specialization aspects but limited consistency between health organization guidelines. Adopting a more specific, measurable, and action-promoting framework for recommendations could improve future guidance in the youth sport community.

Summary: This study systematically reviewed youth sport development guidelines across soccer, basketball, ice hockey, and swimming. It found consensus on the emphasis of early skill development and access to well-trained coaches, but inconsistencies in volume recommendations and lack of proposed methods to monitor athlete well-being. The study highlights the need to create a framework for youth sport specialization to provide specific and consistent guidelines.

Summary: This study proposes a new method of burden assessment using population-weighted age-specific z-scores to measure the burden of different communities. The results show that the ranking based on the new burden measure differs from traditional measures, and it can help prioritize resource allocation to communities with higher burdens.
