• Action recognition in rehabilitation: combining 3D convolution and LSTM with spatiotemporal attention
  This study addresses the limitations of traditional sports rehabilitation, emphasizing the need for improved accuracy and response speed in real-time action detection and recognition in complex rehabilitation scenarios. We propose the STA-C3DL model, a deep learning framework that integrates 3D Convolutional Neural Networks (C3D), Long Short-Term Memory (LSTM) networks, and spatiotemporal attention mechanisms to capture […]
• The role of exercise in restoring executive function: a comparison of tobacco-exposed college athletes and sedentary students
  IntroductionAs adolescent smoking rates rise, its impact on cognitive function has drawn greater attention. This study explores whether exercise can mitigate the negative effects of smoking on executive function in male college students.MethodsSixty male college students were divided into four groups (n = 15 each): sedentary smokers, sedentary nonsmokers, athletic smokers, and athletic nonsmokers. All […]
• Muscle–brain crosstalk mediated by exercise-induced myokines - insights from experimental studies
  Over the past couple of decades, it has become apparent that skeletal muscles might be engaged in endocrine signaling, mostly as a result of exercise or physical activity in general. The importance of this phenomenon is currently studied in terms of the impact that exercise- or physical activity -induced signaling factors have, in the interaction […]
• Hypoxia induces robust ATP release from erythrocytes in ApoE-LDLR double-deficient mice
  Red blood cells (RBCs) play a role in the regulation of vascular tone via release of adenosine triphosphate (ATP) into the vasculature in response to various stimuli. Interestingly, ApoE/LDLR double-deficient (ApoE/LDLR−/−) mice, a murine model of atherosclerosis, display a higher exercise capacity compared to the age-matched controls. However, it is not known whether increased exercise […]
• Exercise combined with artificial gravity and exercise only countermeasures prevent organ and blood vessel morpholgical changes induced by 55 days HDT bedrest
  BackgroundChanges in blood vessel properties have been identified with confinement, spaceflight, bedrest, and dry immersion. Subsequently, it was suspected that other organs may also be affected in these extreme environments. The purposes of the current study were to determine the effects of head-down bedrest (HDT) on cardiovascular and organ measurements made using ultrasound imaging similar […]
• Retraction: Identification of novel SCN5A single nucleotide variants in Brugada syndrome: a territory-wide study from Hong Kong
• Effects of dual-task paradigm on the injury potential during landing among individuals with chronic ankle instability
  PurposeChronic ankle instability (CAI) causes maladaptive neuroplastic changes in the central nervous system, which may lead to high injury potential under dual-task conditions. This study aims to explore the effects of dual-task paradigm on the injury potential during landing among individuals with CAI.MethodsTwenty participants with CAI (4 female and 16 male, 12 were affected with […]
• Left atrial spatial entropy: a novel tool for electrophysiological substrate characterization in atrial fibrillation
  BackgroundElectrical remodeling has been linked to the progression and recurrence of atrial fibrillation (AF) after catheter ablation (CA). Substrate mapping based solely on a voltage amplitude electrogram (EGM) does not provide a comprehensive understanding of the left atrial (LA) disease. The aim of this study is to assess left atrial spatial entropy (LASE) from voltage […]
• Negative pressure breathing: the response of human respiration and circulation to different levels of rarefaction during inspiration
  IntroductionNegative pressure breathing is breathing with decreased pressure in the respiratory tract without lowering pressure acting on the torso. We lowered pressure only during inspiration (NPBin). NPBin is used to increase venous return to the heart and is considered as a countermeasure against redistribution of body fluids toward the head during spaceflight. Aims of our […]
• Impact of a brief series of soccer matches on vascular conditions in youth women
  BackgroundAccumulative excessive physical load elevates central arterial stiffness and smooth muscular tone of peripheral vascular beds in endurance athletes. The aim of this study was to test the hypothesis that a brief series of soccer matches would increase central arterial stiffness and arterial wave reflection from the periphery in young female football players.MethodsFifteen subjects (17.2 […]
