This study investigates the impact of strong hamstrings on stable running and fatigue-induced changes in kinematics. The hamstring muscle group plays a critical role in stabilizing the lower extremities during dynamic movements such as running. However, the extent to which hamstring strength affects running stability and the susceptibility to fatigue-induced alterations in running mechanics remains unclear. Through biomechanical analysis, this research explores how individuals with strong hamstrings maintain stability in running gait and how fatigue alters their kinematic patterns. Understanding these relationships can provide valuable insights into injury prevention strategies and performance optimization for runners.

This study introduces "jump alert," a wearable system designed for inline figure skating jump detection. Inline figure skating, characterized by intricate footwork and jumps, demands precise timing and technique execution. To aid skaters in enhancing their performance and safety, Jump Alert utilizes sensor technology embedded within wearable devices to detect and analyse jump movements in real-time. By monitoring key kinematic parameters and employing machine learning algorithms, Jump Alert accurately identifies jumps during skating routines, providing immediate feedback to skaters and coaches. This innovative system has the potential to revolutionize inline figure skating training and competition by facilitating skill development, injury prevention and performance assessment.

This paper provides an in-depth examination of fine-tuning mechanical loading as a therapeutic approach for knee Osteoarthritis (OA). Knee OA is a prevalent degenerative joint disease characterized by progressive cartilage degradation, pain and functional impairment. While traditional management strategies focus on symptom relief and joint protection, emerging evidence suggests that mechanical loading can play a crucial role in modulating disease progression and promoting joint health. By carefully adjusting the type, duration, frequency and intensity of mechanical loading, clinicians and researchers can tailor interventions to optimize outcomes for individuals with knee OA. This review explores the biomechanical principles underlying mechanical loading, highlights the potential benefits and limitations of different loading modalities and discusses current evidence supporting their efficacy in knee OA management. Additionally, it examines the challenges and opportunities associated with implementing personalized loading strategies in clinical practice, with a focus on advancing precision medicine approaches for optimizing treatment outcomes in knee OA.

This systematic review examines the relationship between female sports participation and the risk of osteoarthritis (OA). With increasing participation of females in sports and physical activities, understanding the potential long-term musculoskeletal consequences is essential for informing injury prevention strategies and promoting lifelong joint health. Osteoarthritis, characterized by joint pain, stiffness and functional impairment, poses a significant public health burden, particularly among aging populations. While sports participation has numerous health benefits, including improved cardiovascular fitness, muscle strength and mental well-being, certain sports and repetitive movements may increase the risk of OA development, particularly in weight-bearing joints such as the knees and hips. Through a comprehensive review of existing literature, this study synthesizes evidence on the association between female sports participation and OA risk, exploring potential risk factors, protective factors and modifiable behaviors that may influence joint health outcomes. Understanding the complex interplay between sports participation, biomechanics, genetics and lifestyle factors can inform targeted interventions to mitigate OA risk and optimize musculoskeletal health in active females across the lifespan.
