Impaired Neural Pattern Separation During Implicit Emotion Regulation in PTSD: An MVPA fMRI Study

Abstract Implicit emotion regulation (IER) operates automatically and supports adaptive social–affective functioning. Although PTSD involves marked IER disturbances, the large-scale functional connectivity architecture supporting implicit emotional processing remains unclear. The...

Biomechanical analysis of lower limb asymmetry in elite junior male Tai Chi athletes: associations with stomping technique performance

Abstract Long-term unilateral dominant training in Tai Chi is commonly associated with lower-limb functional asymmetry in elite athletes, which may correlate with reduced movement proficiency and increased injury susceptibility. This study recruited 80 elite junior male Tai Chi a...

Social anxiety, physical exercise, regulatory emotional self-efficacy, and social avoidance among junior high school students: a cross-sectional study

This study examined the cross-sectional associations of physical exercise (PE), regulatory emotional self-efficacy (RESE), and social avoidance (SAV) with social anxiety (SA) among junior high school students. A school-based cross-sectional survey was conducted among 817 students...

Preoperative clinical and imaging factors associated with arthroscopically confirmed occult syndesmotic instability in patients undergoing surgery for osteochondral lesions of the talus

Aims Osteochondral lesions of the talus (OLTs) are common ankle disorders. Recent clinical observations suggest that a subset of patients with OLTs also exhibit occult syndesmotic instability (OSI) intraoperatively, implying a potential association between the two conditions. Thi...

Optimized design of 3D human pose estimation algorithm based on improved adaptive attention mechanism for sports training

Accurate three-dimensional (3D) human pose estimation is fundamental to sports training analysis, athlete performance monitoring, and rehabilitation guidance. Existing deep learning-based methods are primarily limited by two key deficiencies: (1) fixed receptive fields of convolu...

Associations of structured and unstructured physical activity time in kindergarten with physical fitness in preschoolers: an isotemporal substitution and time threshold analysis

This cross-sectional study aimed to examine how reallocating time across different types of activities is associated with preschoolers’ physical fitness and to identify potential time thresholds that could inform kindergarten activity planning. A total of 337 Chinese preschoolers...

Sprint performance prediction in a national-level database of 58,000 athletes: developmental patterns, population composition effects, and the role of anthropometric features

Abstract Background This study evaluated 100-m sprint performance prediction in one of the largest national-level databases of registered 100-m sprinters analyzed to date, quantified how the target-population definition and the outcome definition shape reported accuracy, and test...

Dose–Response Relationships Between Exercise Modalities and Triglyceride Reduction in Adults: A Systematic Review and Model-Based Network Meta-Analysis

Background/Objectives: Triglyceride-rich lipoproteins contribute to residual atherosclerotic cardiovascular risk, but the comparative and dose–response effects of exercise modalities on triglycerides (TGs) remain uncertain. We compared aerobic exercise (AE), resistance training (...

Ligament Advanced Reinforcement System (LARS) Augmented Repair vs Autograft Reconstruction for Chronic Lateral Ankle Instability: A Retrospective Comparative Study

BACKGROUND: Both autograft reconstruction and Ligament Advanced Reinforcement System (LARS) augmented repair are used for chronic ankle instability (CAI), but comparative evidence regarding postoperative recovery remains limited. This study compared recovery trajectories and func...

Biomechanical and neuromuscular correlates of DaeDo output during successful dominant- and non-dominant-leg taekwondo side kicks: a repeated-measures study

Abstract Objective This study aimed to compare temporal, kinematic, kinetic, and support-side neuromuscular characteristics between dominant- and non-dominant-leg Taekwondo side kicks and to examine their associations with DaeDo output during successful scoring trials. Methods Tw...

DeepPoseCare: a privacy-preserving pose-based temporal convolutional framework for real-time patient action recognition in healthcare environments

Continuous and automated surveillance of patient activities in clinical environments holds great promise for the early identification of falls and distress in patients. However, current vision-based systems face obstacles such as privacy issues, the need for real-time processing,...

Machine learning-based classification of running-related injury status: a cross-sectional study

Abstract Background Running-related injury (RRI) is a common problem affecting runners’ health and training continuity. Although demographic, training-related, and biomechanical factors have been associated with RRI, the use of multidimensional running data to classify injured an...

Career Transition of Elite Athletes: Challenges of Adaptation to Post‐Athletic Life and Proposed Interventions for Sport Career Termination

ABSTRACT This quantitative, descriptive, and survey‐based study investigated career transitions of 221 retired elite athletes in Turkey, focusing on emotional adjustment, coping strategies, and employment challenges. Financial and employment concerns were the main factors influen...

Effects of weighted jump-squat set configuration on acute explosive performance and fatigue responses in resistance-trained men: a randomized crossover study

Weighted jump squats are commonly used to acutely enhance explosive performance, but the optimal organization of repetitions and rest intervals remains unclear. This study compared the effects of traditional, cluster, and rest-redistributed weighted jump-squat configurations on c...

Hydrodynamic characteristics of an ILCA6 sailing dinghy in calm water and head waves

Abstract The ILCA6 (formerly Laser Radial) sailing dinghy frequently encounters wave conditions during training and competition, where wave-induced resistance and ship motions can significantly influence sailing performance. However, systematic investigations of the hydrodynamic...

The influence of maternal complications on small for gestational age in very preterm, late preterm and term pregnancies: a Chinese study

This study aimed to assess the association between single or combined maternal complications and small-for-gestational-age (SGA) birth among very preterm, late preterm, and term births and to evaluate whether this association varied across gestational periods. This retrospective...
