Physical Activity and Depressive Symptoms in Guangdong University Students: A Cross-Sectional Moderated Serial Indirect-Association Model Involving Self-Esteem, Positive Psychological Capital, and Perceived Social Support

Background: This cross-sectional study examined whether physical activity was indirectly associated with depressive symptoms through self-esteem and positive psychological capital and whether these associations varied by perceived social support. Methods: Data from 473 students a...

The Role of Glucose Metabolic Reprogramming in Exercise-Attenuated Osteoporosis: a Narrative Review

BACKGROUND: The aging population has led to a significant increase in the prevalence of osteoporosis, making it an important public health issue. Emerging evidence suggests that osteoporosis is related to glucose metabolic reprogramming (GMR). Exercise is an effective non-pharmac...

Cornus mas L. Ameliorates Hepatic Insulin Resistance in High-fat Diet-induced Diabetic Mice

Background Type 2 diabetes (T2D) remains a prominent chronic metabolic disease characterized by hyperglycemia worldwide. Insulin resistance is the primary risk factor contributing to T2D development. Cornus mas L. is a natural product shown to play a regulatory role in metabolic...

Factors associated with U15-to-U17 roster reappearance in Chinese female youth basketball players: a retrospective longitudinal cohort study

Abstract Background Relative age effects (RAE) are well documented in youth basketball, but whether age-related patterns at U15 are associated with later roster reappearance in multi-birth-year competitions remains unclear. This study examined factors associated with U17 roster r...

Precise Recognition and Evaluation of Men’s Long Jump Based on Transformer and 3D Convolution

For the long jump, the accuracy of action recognition and evaluation affects subsequent training and development plans. Current recognition and evaluation models lack specificity for men’s long jump actions and have low efficiency, which hinders precise and personalized technical...

Effects of β-alanine supplementation on high-intensity intermittent exercise performance and post-exercise blood lactate responses in team-sport athletes: a systematic review and three-level meta-analysis

Abstract Background β-Alanine is widely used for high-intensity exercise, but its effects in team-sport athletes are uncertain. This systematic review and three-level meta-analysis evaluated high-intensity intermittent exercise (HIIE) performance and post-exercise blood lactate....

Associations of physical activity and sleep duration with frailty risk and trajectories in middle-aged and older Chinese adults: a longitudinal cohort study from CHARLS

The levels of physical activity (PA) and sleep duration associated with lower frailty risk and more favorable frailty trajectories among middle-aged and older Chinese adults remain to be further clarified. This study aimed to identify levels of physical activity and sleep duratio...

Advances in the Protective Effects and Mechanisms of β‐Aminoisobutyric Acid in Maintaining Multi‐Organ Homeostasis

ABSTRACT β‐Aminoisobutyric acid (BAIBA) is an exercise‐responsive myokine/metabolite released by skeletal muscle and has attracted increasing interest as a potential exercise mimetic and therapeutic candidate in preclinical research. BAIBA acts locally in skeletal muscle and can...

The effectiveness of different training modes on preplanned change-of-direction performance in basketball players: a systematic review and network meta-analysis

To systematically compare the relative effects of different training modalities on preplanned change-of-direction (COD) performance in basketball players using a Bayesian network meta-analysis. Web of Science, PubMed, ProQuest, and EBSCOhost were systematically searched from ince...

Associations of multiple core stability aspects with drop jump performance

Abstract Background Drop jump performance (DJ) is essential for many ball sports. Core stability (CS) contributes to trunk control and lower-limb capacity during jump movements. The objective of this study was to investigate the relationships between multiple CS aspects and DJ pe...

Immediate spinal and paraspinal muscle responses to Schroth Method exercises in adolescent idiopathic scoliosis: a real-time three-dimensional ultrasonography study

To quantify immediate, real-time changes in three-dimensional spinal alignment and paravertebral muscle parameters during the performance of a single Schroth posture using three-dimensional ultrasonography.This study further aimed to provide an objective, real-time assessment of...

ATF7 drives diabetic wound healing via NOTCH1 repression and N1ICD-dependent macrophage polarization control

Chronic, non-healing wounds are a severe diabetic complication. The underlying mechanisms are not fully understood, and the role of ATF7 in this context has not been well characterized. In our study, we utilized db/db diabetic mice and AAV-mediated keratinocyte-specific Atf7 over...

Prenatal Genetic and Sonographic Features of KBG Syndrome: A Cohort Study of 19 Fetal Cases

ABSTRACT Objective To characterize prenatal sonographic features, genomic findings from chromosomal microarray analysis (CMA) and whole‐exome sequencing (WES), pregnancy outcomes, and postnatal manifestations in KBG syndrome and to provide evidence for prenatal diagnosis and gene...

Mindfulness as a moderator of the association between physical activity enjoyment and academic burnout through self-control in Chinese primary school students

This study aims to examine the association between physical activity enjoyment and academic burnout, testing the mediating role of self-control and the moderating effect of mindfulness in the mediation model. Participants were drawn from twelve primary schools in China using conv...

Exercise-Induced Regulation of Bone Remodeling via Mitophagy: A Review of Current Evidence

Bone remodeling imbalance represents the fundamental pathological basis of osteoporosis. Exercise is broadly regarded as a valuable non-pharmacological strategy for preventing and managing osteoporosis; however, the precise molecular mechanisms through which exercise modulates bo...

Concentric hip work is the most robust lower-limb kinetic correlate of depth-jump height in male collegiate volleyball players

Abstract Background Depth-jump height is commonly used to assess lower-limb explosive performance, but it remains unclear which phase-specific hip, knee, and ankle joint kinetic variables are most consistently associated with performance in volleyball players. Methods In this cro...

Long-Term Weight Variability Is Associated with Higher Triglyceride Concentrations After Accounting for Long-Term Weight Slope

Background: Long-term fluctuations in body weight may reflect changes in energy balance, illness, or intentional weight loss. However, their association with subsequent triglyceride concentrations remains uncertain. Objective: To examine the association between long-term weight v...

Prevalence and associations of biological rhythm disorders with depression and anxiety symptoms in Chinese adolescents: A multicenter study across seven provinces

Biological rhythm disruption is increasingly implicated in adolescent emotional ill-health. We conducted a multicenter cross-sectional survey of 9,498 senior high school students (15–18 years) from seven Chinese provinces. Depressive and anxiety symptoms were assessed with the Pa...
