This study investigated the impact of rehabilitation exercise on functional recovery and morphological changes following thoracic contusive spinal cord injury. After a 7-day recovery period after spinal cord injury, mice were assigned to either a trained group(10 weeks of voluntary running wheel or forced treadmill exercise) or an untrained group. Bi-weekly assessments revealed that the exercise-trained group, particularly the voluntary wheel exercise subgroup, displayed significantly improved locomotor recovery, more plasticity of dopaminergic and serotonin modulation compared with the untrained group. Additionally, exercise interventions led to gait pattern restoration and enhanced transcranial magnetic motor-evoked potentials. Despite consistent injury areas across groups, exercise training promoted terminal innervation of descending axons. In summary, voluntary wheel exercise shows promise for enhancing outcomes after thoracic contusive spinal cord injury, emphasizing the role of exercise modality in promoting recovery and morphological changes in spinal cord injuries. Our findings will influence future strategies for rehabilitation exercises, restoring functional movement after spinal cord injury.展开更多

文摘Physical activity,moderate aerobic or resistance exercise are well established to offer health benefits and promote healthy aging and longevity.^(1)In contrast,lack of exercise contributes to adverse events,especially in some patients with organ failure.^(2)Therefore,“exercise pills”and“exercise mimetics”have attracted growing interest because of their potential to induce exercise-related health effects despite physical exercise not being performed.^(3)Robust studies over the past decade have identified many natural biomacromolecules,such as peptide,non-coding Ribonucleic Acid(RNAs),and lipids,that are induced by exercise.^(4-6)These molecules trigger physiological adaptations,including promotion of cardiomyocyte proliferation,anti-apoptotic capacity,and healthy tissue growth.7However,identifying or designing an exercise pill that mimics the extensive benefits of exercise is still challenging.
文摘Background:Insufficient physical activity and prolonged sedentary behavior have emerged as major global public health challenges.Short bouts(≤10 min)of accumulated exercise(SBAE)throughout the day may be a promising strategy to mitigate the adverse effects of prolonged sitting and promote physical activity,ultimately promoting overall health.However,previous ambiguity in defining this concept has resulted in a fragmented and inconsistent evidence base,impeding practical applications,the development of guidelines,and policymaking.The purpose of this study is to establish an operational definition of SBAE by synthesizing systematic reviews and research trials alongside an expert consensus.Additionally,it seeks to evaluate acute and long-term efficacy and feasibility,providing evidence-based recommendations for practice and future research directions.Methods:A literature search was performed across PubMed and Web of Science,followed by systematic screening and summarization of eligible studies based on predefined inclusion criteria.Inclusion criteria encompassed various modes/types of SBAE(bouts lasting≤10 min,performed multiple times daily with≥30 min intervals);both aerobic and resistance exercise were considered.Relevant systematic reviews and research trials were included.Methodological quality,risk of bias,and evidence certainty were assessed.Expert consensus was obtained through a survey to evaluate recommendations and agreement levels on findings.Results:After analyzing 27 systematic reviews,135 research studies,and an expert consensus involving 48 researchers from 11 countries,SBAE is defined as any exercise mode of activity,regardless of intensity,that is accumulated in either continuous or intermittent bouts lasting≤10 min per session(including multiple intermittent sets)that are performed multiple times(≥2 sessions/day)per day,with intervals of≥30 min between bouts or otherwise sufficient time for recovery.When used to interrupt prolonged periods of sedentary time,SBAE mitigates the acute adverse effects of sedentary behavior on more than 10 clinical biomarkers of endocrine,cardiovascular,and brain health/function among adults of diverse ages and conditions.Moreover,SBAE was superior for improving acute glycemic control compared to a single continuous exercise session.As a long-term intervention(average of 11 weeks),SBAE can improve over 20 health outcomes,including peak oxygen uptake,resting blood pressure,and metabolic health.Additionally,SBAE might be more effective than continuous exercise for improving longer-term glycemic control and body composition.Long-term completion rates for SBAE interventions are generally high(95%),with low dropout rates(12%)and high adherence rates even without supervision(85%),and its safety has been preliminarily validated.Conclusion:An operational definition of SBAE is provided along with its classification and acute and long-term efficacy.Practical exercise prescription recommendations and evidence-based strategies for various populations and contexts are provided.Future research should focus on generating high-quality evidence for SBAE in 5 key areas:quantification and monitoring,population-specific responses,optimization of exercise prescriptions,intervention efficacy,and practical implementation.Additionally,addressing policy,environmental,and promotional barriers is crucial for transitioning from expert consensus to public consensus,and for facilitating the application of this strategy in real-world environments.
文摘1.Introduction The field of exercise science is experiencing a renaissance,with recent research illuminating the molecular,cellular,and systemic effects of physical activity.This is largely due to the now unequivocal evidence that a lack of physical activity,not only has direct effects on the prevalence of non-contagious diseases(NCDs)but has profound additive effects of other risk factors for NCD such as obesity and hypertension.1 The articles in this special topic of Journal of Sport and Health Science(JSHS)are dedicated to research on Exercise biochemistry&metabolism.

文摘Methamphetamine(METH)addiction is a severe and increasingly prevalent neuropsychiatric disorder for which current diagnostic and therapeutic approaches remain limited and predominantly symptom-oriented.Exercise,as a safe,accessible and cost-effective non-pharmacological intervention,has emerged as a promising strategy to ameliorate METH-induced neurotoxicity and addiction-related behaviors.Growing evidence indicates that these benefits are closely linked to the regulation of exercise-induced biomarkers,defined as molecular indicators whose expression or activity is dynamically altered during or after physical activity.This review focuses on the core regulatory role of exercise-induced biomarkers in METH addiction and systematically summarizes their involvement in key neurobiological pathways,outlining molecular pathological mechanisms such as dysregulation of dopamine,glutamate and GABA neurotransmitter systems,neuroinflammation and oxidative stress,and epigenetic remodeling,and emphasizing how these processes converge on changes in candidate biomarkers in the brain and periphery.On this basis,the review describes how exercise modulates neural plasticity,neurotransmitter systems,inflammation and oxidative stress through biomarkers such as brain-derived neurotrophic factor(BDNF),exerkines,inflammatory cytokines,metabolites and noncoding RNAs,with particular attention to neurotrophic and immune-related markers,microRNAs and other epigenetic regulators that can reverse METH-induced synaptic and structural abnormalities and promote recovery of cognitive and emotional functions.Advances in high-throughput omics technologies,including transcriptomics,metabolomics and multi-omics integration,are summarized to illustrate the screening and identification of key exercise-responsive biomarkers.Studies in METH-addicted animal models have revealed differentially expressed genes,signaling pathways(e.g.,PI3K-Akt,mTOR,Wnt)and core nodes such as NFKBIA and CXCL12 that may mediate the protective effects of exercise.The review further discusses the potential of exercisemediated biomarkers as objective indicators for diagnosis,dynamic monitoring of therapeutic efficacy and patient stratification.Multi-gene diagnostic models based on peripheral samples(e.g.,hair follicles,blood)demonstrate how biomarker panels can distinguish non-recovered,almost-recovered and healthy individuals,providing a molecular basis for staging METH use disorder and evaluating the impact of exercise interventions.The temporal dynamics of biomarker changes before and after exercise are highlighted,underscoring the value of longitudinal monitoring of factors such as BDNF,immune-related genes and circulating microRNAs to capture treatment-relevant windows of plasticity.In addition,the underlying molecular basis of exercise as an adjunct therapy and gene-targeted exercise strategies that leverage individual biomarker and gene expression profiles to optimize exercise prescriptions are summarized.Current conceptual and technical challenges are outlined,including heterogeneity of biomarker responses,individual variability,assay sensitivity and specificity,and gaps between preclinical findings and clinical application,together with future directions for integrating exercise with multi-omics,artificial intelligence-assisted biomarker discovery and,prospectively,gene-editing-based interventions.Particular emphasis is placed on the need to standardize exercise protocols,incorporate stage-specific and sex-sensitive designs,and combine exercise with pharmacotherapy and psychosocial rehabilitation in real-world clinical settings across diverse healthcare systems.Overall,this review aims to provide a comprehensive and integrated mechanistic framework and updated theoretical support for the application of exercise-mediated biomarkers in the diagnosis,therapeutic effect monitoring and personalized intervention of METH addiction,and to offer new and clinically relevant insights into the development of precision medicine strategies for substance use disorders.

文摘Spinal cord injury is a severe neurological condition characterized by the permanent loss of nerve cell function and a failure in neural circuit reconstruction-key factors contributing to disability.Therefore,exploring effective strategies to promote the repair and regeneration of nerve cells after spinal cord injury is crucial for optimizing patient prognosis.The purpose of this paper is to conduct an in-depth review of the pathological changes in nerve cells after spinal cord injury and to present the state of research on the role of exercise training in promoting the repair and regeneration of nerve cells after spinal cord injury.In terms of the intrinsic growth capacity of neurons,disruptions in the dynamic balance between growth cones and the cytoskeleton,the dysregulation of transcription factors,abnormal protein signaling transduction,and altered epigenetic modifications collectively hinder axonal regeneration.Additionally,the microenvironment of neurons undergoes a series of complex changes,initially manifesting as edema,which may be exacerbated by spinal cord ischemia-reperfusion injury,further increasing the extent of nerve cell damage.The abnormal proliferation of astrocytes leads to the formation of glial scars,creating a physical barrier to nerve regeneration.The inflammatory response triggered by the excessive activation of microglia negatively impacts the process of nerve repair.Non-invasive interventions involving exercise training have shown significant potential in promoting nerve repair as part of a comprehensive treatment strategy for spinal cord injury.Specifically,exercise training can reshape the growth cone and cytoskeletal structures of neurons,regulate transcription factor activity,modulate protein signaling pathways,and influence epigenetic modifications,thereby activating the intrinsic repair mechanisms of neurons.Moreover,exercise training can regulate the activation state of astrocytes,optimize the inflammatory response and metabolic processes,promote astrocyte polarization,enhance angiogenesis,reduce glial scar formation,and modulate the expression levels of nerve growth factors.It also effectively helps regulate microglial activation,promotes axonal regeneration,and improves phagocytic function,thereby optimizing the microenvironment for nerve repair.In terms of clinical translation,we summarize the preliminary results of new drug research and development efforts,the development of innovative devices,and the use of exercise training in promoting clinical advancements in nerve repair following spinal cord injury,while considering their limitations and future application prospects.In summary,this review systematically analyzes findings relating to the pathological changes occurring in nerve cells after spinal cord injury and emphasizes the critical role of exercise training in facilitating the repair and regeneration of nerve cells.This work is expected to provide new ideas and methods for the rehabilitation of patients with spinal cord injury.

文摘Alzheimer's disease is the primary cause of dementia and imposes a significant socioeconomic burden globally.Physical exercise,as an effective strategy for improving general health,has been largely reported for its effectiveness in slowing neurodegeneration and increasing brain functional plasticity,particularly in aging brains.However,the underlying mechanisms of exercise in cognitive aging remain largely unclear.Adiponectin,a cell-secreted protein hormone,has recently been found to regulate synaptic plasticity and mediate the antidepressant effects of physical exercise.Studies on the neuroprotective effects of adiponectin have revealed potential innovative treatments for Alzheimer's disease.Here,we reviewed the functions of adiponectin and its receptor in the brains of human and animal models of cognitive impairment.We summarized the role of adiponectin in Alzheimer's disease,focusing on its impact on energy metabolism,insulin resistance,and inflammation.We also discuss how exercise increases adiponectin secretion and its potential benefits for learning and memory.Finally,we highlight the latest research on chemical compounds that mimic exerciseenhanced secretion of adiponectin and its receptor in Alzheimer's disease.

文摘Background Obesity is a risk factor for developing cardiometabolic disease.Exercise training is pivotal in the treatment of obesity and is associated with reduced cardiovascular mortality.This study examined the effect of high-fat feeding on cardiac morphology and mitochondrial function,alongside the mitigating effects of voluntary exercise training.Methods Six-week-old male C57Bl/6 J mice commenced a high fat diet(HFD)or chow diet and were randomized to receive locked(sedentary)or unlocked(voluntary exercise training(VET))running wheels at 10 weeks of age.Mice were monitored until 30 weeks of age and euthanized for collection of tissues.Magnetic resonance imaging was performed to assess body composition,and echocardiography was performed to assess cardiac function.Results Compared with chow-fed animals,the HFD increased body weight and adiposity and decreased cardiolipins(CL)in the heart,which are required for maintaining adequate mitochondrial respiration.Importantly,VET reversed these effects and induced physiological cardiac hypertrophy.Cardiac mitochondrial respiratory chain analysis revealed decreased complexes II and IV activity following high fat feeding,while VET enhanced complex I activity,emphasizing the cardioprotective effect of exercise training in obesity.Conclusion This study uncovers mechanisms by which obesity and exercise impact cardiac mitochondrial health and suggests the mitochondria is a therapeutic target in obesity-related cardiovascular diseases.

文摘Overweight and obesity are significant public health concerns worldwide due to their association with many chronic health conditions.This has resulted in the development of various interventions focused on weight loss to reduce the associated health burden.Physical activity is an important lifestyle behavior associated with enhanced health.Evidence supports that many of the benefits of physical activity are realized independent of initial weight status or whether weight loss is achieved,with some benefits additive to what is achieved with weight loss alone.These benefits include enhanced cardiometabolic,brain,cognitive and psychological health,and others.Moreover,in adults with overweight or obesity,physical activity has independent effects on cardiorespiratory fitness,muscular strength,physical function,and mobility.There are also benefits to body composition,with physical activity improving the quality of key tissues,such as skeletal muscle,which may not occur with diet-induced weight loss.Therefore,physical activity is an important public health target for adults with overweight or obesity to provide a wide range of health benefits that extend beyond those of weight loss alone.However,physical activity recommendations and programming efforts should consider the unique characteristics of adults with overweight or obesity to be most effective,and should support a focus on mobility,physical function,and other health outcomes.
文摘Objective This study aimed to evaluate whether cardiac rehabilitation with a technology-assisted personalized exercise prescription is superior to traditional remote home-based rehabilitation in improving cardiorespiratory endurance and quality of life in postoperative patients.Methods From October 2022 to April 2024,62 patients who underwent percutaneous coronary intervention for coronary heart disease were recruited from a tertiary hospital in Beijing and randomly assigned to either an intervention group or a control group.After baseline assessments of cardiorespiratory endurance and exercise function,the intervention group received a digitalized personalized exercise prescription combined with remote monitoring rehabilitation.This included an exercise prescription delivered via a mobile application,weekly remote monitoring sessions with an exercise therapist to supervise prescription adherence,provide feedback based on real-time electrocardiographic data,and make personalized adjustments to the exercise prescription based on this information.The control group received an application-delivered exercise movement library and a wearable electrocardiogram device for self-monitoring of exercise intensity.Both groups underwent the 12-week intervention.Changes in maximal oxygen uptake and quality of life were evaluated at enrollment,as well as at 4 weeks,12 weeks,and 24 weeks after the intervention commenced.Results A total of 58 participants completed the study(the intervention group[n=30],the control group[n=28]).Twelve weeks after the interventions,the intervention group showed statistically improvements in VO2AT(Z=2.247,P=0.025),general health(Z=2.126,P=0.033)and social functioning(Z=3.349,P=0.001)compared to the control group.At 24 weeks of follow-up,the intervention group continued to exhibit statistically significant improvements in VO2AT(Z=2.017,P=0.044)and social functioning(Z=3.126,P=0.002).The exercise duration of patients in the intervention group during the exercise test was significantly prolonged at both 4 weeks(Z=−2.420,P=0.021),12 weeks(Z=−2.240,P=0.029)and 24weeks(Z=−2.300,P=0.025)showing statistically significant differences compared to the control group.Conclusions This study provides new evidence-based support for the practical effectiveness of nurses acting as supervisors of rehabilitation implementation and coordinators of multidisciplinary teams within a remote digital cardiac rehabilitation model,underscoring their significant value in the secondary prevention management system for cardiovascular diseases in the information era.

文摘White matter injury is a key factor impacting stroke recovery.Physical exercise can promote white matter repair.Immune cells,especially regulatory T(Treg)cells,contribute to strengthening white matter integrity,yet little is known about the underlying mechanism.To examine this,we established a transient middle cerebral artery occlusion male mouse model.We found that physical exercise elevated brain Treg cells,thereby enhancing neurological recovery,reducing neuroinflammation,promoting myelin debris clearance,and accelerating white matter repair.Depletion of Treg cells caused a decrease in these positive effects of physical exercise.Mechanistically,the rise in osteopontin triggered by physical exercise is dampened when Treg cells are depleted.In addition,Treg-conditioned medium reduced oxygen-glucose deprivation/re-oxygenation-induced microglial inflammation and enhanced phagocytosis,which could be blocked by osteopontin antibodies.Importantly,although Treg infusion could mimic the protective effects of physical exercise,osteopontin blockade partially countered the effects of physical exercise and Treg cells.Finally,our sequencing data revealed a marked upregulation of C-X-C motif chemokine ligand 12(CXCL12)mRNA expression subsequent to physical exercise,which was confirmed at the protein level.Stimulation of Treg cells with stroke brain lysates increased C-X-C motif chemokine receptor 4(CXCR4)expression,indicating a potential role for the CXCL12-CXCR4 axis in recruiting Treg cells.These findings suggest that physical exercise promotes white matter repair after ischemic stroke by Treg cells.

文摘Background:Midlife lifestyle factors,including physical activity,are associated with late-life brain health,yet the role of aerobic exercise on structural brain health in early and mid-adulthood remains poorly understood.This study aimed to examine the effect of aerobic exercise on structural brain age and to explore potential mediators.Methods:In a single-blind,12-month randomized clinical trial,130 healthy participants aged 26-58 years were randomized into a moderate-to-vigorous intensity aerobic exercise group or a usual-care control group.The exercise group attended two supervised 60-min sessions per week in a laboratory setting plus engaged in home-based exercise to achieve 150 min of exercise per week.Brain-predicted age difference(brain-PAD)and cardiorespiratory fitness(CRF)were assessed at baseline and 12 months.Both intention-to-treat(ITT)and completers analyses(including participants who completed post-intervention assessments)were performed.Results:The 130 participants(67.7%female)had an age of 41.28±9.93 years(mean±SD).At baseline,higher CRF(peak oxygen uptake,VO_(2peak))was associated with smaller brain-PAD(β=-0.309,p=0.012).After the intervention,the exercise group showed a decrease in brainPAD(estimated mean difference(EMD)=-0.60;95%confidence interval(95%CI):-1.15 to-0.04;p=0.034)compared to the control group(EMD=0.35;95%CI:-0.21 to 0.92;p=0.217);time×group interaction(between-group difference(BGD)=-0.95;95%CI:-1.72 to-0.17;p=0.019).VO2peak improved in the exercise group(EMD=1.60;95%CI:0.29-2.90;p=0.017)compared to the control group(EMD=-0.78;95%CI:-2.17 to 0.60;p=0.265);time×group interaction(BGD=2.38;95%CI:0.52-4.25;p=0.015).Body composition,blood pressure,and brain-derived neurotrophic factor levels were unaffected.None of the proposed pathways statistically mediated the effect of exercise on brain-PAD.The results from completers were similar.Conclusion:Engaging in 12 months of moderate-to-vigorous exercise reduced brain-PAD in early-to-midlife adults.The pathways by which these effects occur remain unknown.
文摘This scoping review aims to synthesize evidence on exercise interventions for adolescents with depression by examining their components and evaluating their effects,thereby informing the development of standardized exercise programs for this population.Based on the Arksey and O’Malley framework for scoping reviews,the following databases were systematically searched:PubMed,Web of Science,Cochrane Library,Embase,EBSCO,China National Knowledge Infrastructure,Wanfang Database,VIP Database,and China Biomedical Literature Database.Based on the inclusion and exclusion criteria,the original studies applying exercise intervention in adolescents with depression were screened.A total of 9 papers were included,including 7 randomized controlled trials,1 quasi-experimental study,and 1 mixed study.The types of exercise interventions included aerobic exercise,resistance training,anti-gravity exercise,and stretching.The frequency of exercise was 30–60 min,3–5 times per week in most studies,with most intensities being moderate to high.Exercise intervention is feasible and effective in adolescents with depression.Nursing staff play a crucial role in implementing and supervising these interventions,from initial assessment to continuous monitoring of motivation and safety.In future studies,healthcare professionals should focus on assessing the condition and physical functional status of adolescents with depression and improving the specific content of exercise intervention to develop a scientific and standardized exercise training program for adolescents with depression.

文摘Background Maternal obesity during pregnancy can lead to increased risk for metabolic disease in offspring during adulthood,helping fuel the worldwide increase in obesity.Fortunately,studies in rodent models have established that female dams(F0)that perform voluntary wheel running exercise during pregnancy have first-generation(F1)offspring with improved glucose tolerance,suggesting a potential means to reduce the burden of generational metabolic disease transmission.We have shown that maternal exercise also affects F1 male offspring as sires,as their progeny(F2)have similarly improved metabolic health.Whether maternal exercise can affect F1 females in a manner that improves F2 offspring metabolism is not known.Here,we determined whether voluntary exercise by F0 grandmothers,via their F1 female progeny,produced F2 male and female offspring with an improved metabolic phenotype.Methods Six-week-old C57BL/6 N female mice(F0)were fed a chow diet and either kept sedentary or exercise trained by voluntary wheel running for 2 weeks preconception and during pregnancy.Chow-fed sedentary F1 female offspring at 8 weeks of age were bred with age-matched untreated virgin males to generate F2 offspring.F2 were kept sedentary and chow fed and studied up to 52 weeks of age.Metabolic parameters were assessed,including food intake,body weight,body composition,glucose tolerance,systemic glucose and insulin levels,and liver metabolism.Results Grandmaternal exercise did not significantly alter male and female F2 offspring body weights measured throughout the first year of life,nor was there an effect of grandmaternal exercise on F2 offspring fat mass or lean mass.Remarkably,despite the lack of effect on body weight parameters,grandmaternal exercise resulted in improved glucose tolerance and homeostatic model assessment for insulin resistance(HOMA-IR)in F2 offspring at 52 weeks of age,effects that were more pronounced in male F2 offspring.Conclusion Voluntary wheel running exercise in female mice during pregnancy leads to metabolic improvements in her grand offspring,despite no direct intervention of the intermediate maternal generation.Maternal physical activity during pregnancy may reduce metabolic diseases in later generations.

文摘Spinal cord injury necessitates effective rehabilitation strategies, with exercise therapies showing promise in promoting recovery. This study investigated the impact of rehabilitation exercise on functional recovery and morphological changes following thoracic contusive spinal cord injury. After a 7-day recovery period after spinal cord injury, mice were assigned to either a trained group(10 weeks of voluntary running wheel or forced treadmill exercise) or an untrained group. Bi-weekly assessments revealed that the exercise-trained group, particularly the voluntary wheel exercise subgroup, displayed significantly improved locomotor recovery, more plasticity of dopaminergic and serotonin modulation compared with the untrained group. Additionally, exercise interventions led to gait pattern restoration and enhanced transcranial magnetic motor-evoked potentials. Despite consistent injury areas across groups, exercise training promoted terminal innervation of descending axons. In summary, voluntary wheel exercise shows promise for enhancing outcomes after thoracic contusive spinal cord injury, emphasizing the role of exercise modality in promoting recovery and morphological changes in spinal cord injuries. Our findings will influence future strategies for rehabilitation exercises, restoring functional movement after spinal cord injury.

文摘BACKGROUND Type 2 diabetes mellitus(T2DM),a chronic metabolic disease with a high global incidence,has become a serious public health challenge.China has the largest number of T2DM patients worldwide,imposing a significant economic burden on the healthcare system.T2DM is closely associated with insulin resistance,impaired pancreatic B cell function,and disordered glucose and lipid metabolism,which can lead to various complications,reducing patients'quality of life and increasing the risk of disability and death.Thus,finding effective preventive and intervention measures is crucial.Exercise therapy,a key part of diabetes management,has gained attention in recent years,with many studies indicating its benefits for blood glucose control and other aspects in diabetic patients.AIM To assess the effectiveness of combined resistance and aerobic exercise interventions on blood glucose control and metabolic indicators in patients with T2DM and to explore their application in diabetes management.METHODS Systematic searches were conducted using PubMed,EMBASE,Cochrane Library,and Chinese databases for relevant randomized controlled trials(RCTs).The inclusion criteria were participants aged≥18 years with T2DM and the intervention involved combined resistance and aerobic exercise for≥8 weeks.The primary outcome indicators were fasting blood glucose,low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),triglycerides(TG),glycated hemoglobin A1c(HbA1c),and total cholesterol(TC)levels.Data analysis was performed using RevMan software,and the interventional effects were assessed using weighted mean differences or standardized mean differences(SMD).RESULTS Six RCTs meeting the inclusion criteria were included,with a total sample size of 366 participants.The meta-analysis results showed that combined resistance and aerobic exercise significantly improved several metabolic indicators in patients with T2DM.Specific results were as follows:(1)For fasting blood glucose,combined exercise was more effective than aerobic exercise alone[SMD=1.22;95%confidence interval(95%CI):0.70,1.74;P<0.00001];(2)LDL-C levels were significantly reduced by the combined intervention(SMD=1.45;95%CI:1.18-1.72;P<0.00001);(3)The combined intervention significantly increased HDL-C levels(SMD=1.42;95%CI:0.98-1.87;P<0.00001);(4)The combined intervention significantly reduced TG levels(SMD=1.12;95%CI:0.85-1.39;P<0.00001;(5)No statistically significant difference was observed in HbA1c between the combined and the aerobic exercise group(SMD=-0.03;95%CI:-1.09 to 1.04;P<0.00001);and(6)The combined exercise intervention group significantly reduced TC levels(SMD=2.66;95%CI:1.93-3.38;P<0.00001).The subgroup analysis results suggest that the effect of exercise interventions may be influenced by various factors,including the patient's age,baseline blood glucose levels,and exercise intensity.CONCLUSION Combined resistance and aerobic exercise intervention significantly improved fasting blood glucose,LDL-C,HDL-C,TG,and TC levels in patients with T2DM,especially in terms of blood glucose control and cardiovascular risk,demonstrating better outcomes than aerobic exercise alone.
文摘BACKGROUND The relationship between exercise and gastrointestinal(GI)health is complex and bidirectional.While moderate exercise generally promotes gut health by enhancing motility,reducing inflammation,and supporting microbial balance,intense or prolonged physical activity may exacerbate GI symptoms,particularly in individuals with preexisting digestive disorders.A deeper understanding of this interplay is essential for optimizing both exercise performance and GI well-being.AIM To synthesize current evidence on exercise-related GI disorders,exploring the prevalence,mechanisms,risk factors,and management strategies associated with exercise-induced GI symptoms.METHODS Following PRISMA guidelines,comprehensive searches of databases,including PubMed,Scopus,Web of Science,and EMBASE were conducted.Studies were included if they focused on exercise-induced GI disorders,encompassed randomized controlled trials,cohort studies,case-control studies,and cross-sectional designs,and addressed symptoms across various exercise modalities.Data were extracted and analyzed to identify patterns and implications for clinical and athletic practice.RESULTS A total of 231 studies met the inclusion criteria,highlighting both the benefits and risks of exercise on GI health.Regular moderate-intensity exercise,including activities such as walking,cycling,and yoga has been associated with improved GI function in conditions like gastroesophageal reflux disease,irritable bowel syndrome,inflammatory bowel disease,and constipation.These benefits are attributed to enhanced intestinal motility,reduced systemic inflammation,and improved gut barrier integrity.Additionally,exercise plays a role in regulating the gut-brain axis,with practices like yoga and Tai Chi demonstrating particular effectiveness in alleviating functional GI disorders.Conversely,high-intensity or prolonged exercise may contribute to symptoms such as nausea,diarrhea,and abdominal pain due to mechanisms like splanchnic hypoperfusion and increased intestinal permeability.Individual factors,including fitness level,dietary habits,hydration status,and underlying GI conditions,significantly influence the body’s response to exercise.CONCLUSION Moderate-intensity exercise is a beneficial and well-tolerated intervention for promoting GI health,whereas highintensity activities require careful monitoring,particularly in individuals with pre-existing GI disorders.Personalized exercise and dietary strategies are essential for balancing the benefits of physical activity with the risk of GI distress.Further research is needed to explore the long-term effects of exercise on gut microbiota composition and overall digestive health.

文摘Cerebral ischemia is a major health risk that requires preventive approaches in addition to drug therapy.Physical exercise enhances neurogenesis and synaptogenesis,and has been widely used for functional rehabilitation after stroke.In this study,we determined whether exercise training before disease onset can alleviate the severity of cerebral ischemia.We also examined the role of exercise-induced circulating factors in these effects.Adult mice were subjected to 14 days of treadmill exercise training before surgery for middle cerebral artery occlusion.We found that this exercise pre-conditioning strategy effectively attenuated brain infarct area,inhibited gliogenesis,protected synaptic proteins,and improved novel object and spatial memory function.Further analysis showed that circulating adiponectin plays a critical role in these preventive effects of exercise.Agonist activation of adiponectin receptors by Adipo Ron mimicked the effects of exercise,while inhibiting receptor activation abolished the exercise effects.In summary,our results suggest a crucial role of circulating adiponectin in the effects of exercise pre-conditioning in protecting against cerebral ischemia and supporting the health benefits of exercise.

文摘Recent research has demonstrated the impact of physical activity on the prognosis of glioma patients,with evidence suggesting exercise may reduce mortality risks and aid neural regeneration.The role of the small ubiquitin-like modifier(SUMO)protein,especially post-exercise,in cancer progression,is gaining attention,as are the potential anti-cancer effects of SUMOylation.We used machine learning to create the exercise and SUMO-related gene signature(ESLRS).This signature shows how physical activity might help improve the outlook for low-grade glioma and other cancers.We demonstrated the prognostic and immunotherapeutic significance of ESLRS markers,specifically highlighting how murine double minute 2(MDM2),a component of the ESLRS,can be targeted by nutlin-3.This underscores the intricate relationship between natural compounds such as nutlin-3 and immune regulation.Using comprehensive CRISPR screening,we validated the effects of specific ESLRS genes on low-grade glioma progression.We also revealed insights into the effectiveness of Nutlin-3a as a potent MDM2 inhibitor through molecular docking and dynamic simulation.Nutlin-3a inhibited glioma cell proliferation and activated the p53 pathway.Its efficacy decreased with MDM2 overexpression,and this was reversed by Nutlin-3a or exercise.Experiments using a low-grade glioma mouse model highlighted the effect of physical activity on oxidative stress and molecular pathway regulation.Notably,both physical exercise and Nutlin-3a administration improved physical function in mice bearing tumors derived from MDM2-overexpressing cells.These results suggest the potential for Nutlin-3a,an MDM2 inhibitor,with physical exercise as a therapeutic approach for glioma management.Our research also supports the use of natural products for therapy and sheds light on the interaction of exercise,natural products,and immune regulation in cancer treatment.
