Keywords included“exercise,” “physical activity,” and “anxiety disorder.”Results and conclusions: Current research widely supports exercise as a safe and effective intervention for anxiety.Both aerobic exercise and resistance training have shown significant anxiety-reducing effects across various populations. The mechanisms of action can be categorized into three main types: cellular and molecular mechanisms, systemic immune effects, and behavioral and cognitive pathways. Different forms of exercise have distinct advantages: aerobic exercise is suitable for the general population, resistance training is beneficial for individuals with coexisting physical conditions, and low-intensity exercises such as yoga and Tai Chi are suitable for pregnant women, the elderly, or postoperative recovery patients. Given its good safety profile and broad applicability, moderate exercise should be considered a first-line treatment for mild anxiety and an adjunctive intervention for moderate to severe anxiety. Future research should further clarify the mechanistic differences between various exercise modalities and promote the development of individualized exercise prescriptions.展开更多

In contrast, serum creatine levels were unaffected by exercise(p = 0.80), while creatinine levels exhibited a strong tendency to decrease post-exercise(from [81.8 ±17.5] μmol·L^(-1) to [73.1 ± 11.6] μmol·L^(-1);p = 0.06). A comparison of the slopes of the two regression lines(saliva vs. serum) revealed significant differences for both creatine(p = 0.01) and creatinine(p = 0.03).Conclusions: The above findings suggest a potential difference in the dynamics of creatine metabolites in these two bodily fluids, both pre and post-exercise.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Exercise,as a non-pharmacological health intervention,has been widely recognized for its beneficial effects,yet its underlying molecular mechanisms remain incompletely understood.The duration,frequency,and intensity of exercise exert distinct physiological impacts on the human body[1].Notably,acute exercise(AE)primarily elicits immediate metabolic responses and immune activation to cope with environmental stimuli,whereas long-term exercise(LE)induces cumulative health benefits across multiple organ systems[2‒4].Aging represents a complex biological process that persists throughout the ontogenetic continuum and serves as a pivotal etiological determinant for numerous chronic pathologies.In the context of accelerating global demographic aging,the development of interventions to promote healthspan extension and modulate aging trajectories has become a paramount research imperative in geroscience.Currently,research on the relationship between exercise and aging is a hot topic.For example,exercise has been shown to modulate aging through pathways such as AMP-activated protein kinase(AMPK)[5].However,the precise molecular links remain elusive.In a recent breakthrough study,Geng et al.used a novel multi-omics strategy to pinpoint betaine,a glycine derivative from choline/diet that serves as both a hepatic methyl donor and a renal osmoprotectant,as a key exercise-induced molecule with anti-inflammatory and geroprotective effects mediated partially via TANK-binding kinase 1(TBK1)inhibition[6,7].This work represents a significant advance as it systematically maps the molecular divergence between acute and long-term exercise while establishing a direct link between renal metabolism and systemic senescence-delaying benefits.
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Objective:To observe the effect of acupuncture combined with the Thirteen-posture Tai Chi exercise prescription on the rehabilitation of cervical radiculopathy(CR).Methods:A total of 159 patients diagnosed with CR were enrolled in a prospective study.They were randomly divided into an acupuncture group,an exercise group,and a combined group using the random number table method,with 53 cases in each group.All three groups received routine Western rehabilitation training.In addition,the acupuncture group was treated with“Si Tian Xue”[four points with“Tian”in their names,including Tianyou(TE16),Tianchuang(SI16),Tianrong(SI17),and Tianding(LI17)]acupuncture.The exercise group practiced according to the Thirteenposture Tai Chi exercise prescription.The combined group received“Si Tian Xue”acupuncture combined with the Thirteen-posture Tai Chi exercise prescription.All interventions lasted for 12 weeks in three groups.The neck disability index(NDI)and visual analog scale(VAS)scores were compared among the three groups before treatment and after 6 and 12 weeks of treatment.Before treatment and after 12-week treatment,the range of motion(ROM)of cervical in left rotation,right rotation,extension,and flexion,as well as the mean power frequency(MPF)of surface electromyography(sEMG)signals of the erector spinae and trapezius,the average blood flow velocity of the vertebral and basilar arteries,and the short-form 36-item health survey(SF-36)score was compared among the three groups.Results:After 6 and 12 weeks of treatment,the NDI and VAS scores of the three groups were significantly lower than those before treatment(P<0.05),and the NDI and VAS scores of the combined group were significantly lower than those of the acupuncture group and the exercise group at the same time points(P<0.05).After treatment,the cervical ROM in left rotation,right rotation,extension,and flexion in the three groups was significantly higher than that before treatment(P<0.05),and the combined group was significantly higher than the acupuncture group and the exercise group(P<0.05).After treatment,the MPF of the erector spinae and trapezius and the average blood flow velocity of the vertebral and basilar arteries in the three groups were significantly higher than those before treatment(P<0.05),and the combined group was significantly higher than the acupuncture group and the exercise group(P<0.05).After treatment,the SF-36 score of the three groups was significantly higher than that before treatment(P<0.05),and it was significantly higher in the combined group than in the acupuncture group and the exercise group(P<0.05).Conclusion:Compared to“Si Tian Xue”acupuncture or the Thirteen-posture Tai Chi exercise prescription alone,the combination of the two can more effectively improve cervical function and microcirculation,relieve pain,and improve the quality of life in patients with CR.

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Objective: This review aims to explore the efficacy of exercise in the treatment of anxiety disorders and its underlying mechanisms, summarizing recent research advances and focusing on the potential biological and psychological pathways through which exercise exerts its anxiolytic effects.Methods: To ensure comprehensive coverage of relevant studies, we conducted a systematic search in databases such as PubMed, Web of Science, and Embase, combining MeSH terms with free-text terms. Keywords included“exercise,” “physical activity,” and “anxiety disorder.”Results and conclusions: Current research widely supports exercise as a safe and effective intervention for anxiety.Both aerobic exercise and resistance training have shown significant anxiety-reducing effects across various populations. The mechanisms of action can be categorized into three main types: cellular and molecular mechanisms, systemic immune effects, and behavioral and cognitive pathways. Different forms of exercise have distinct advantages: aerobic exercise is suitable for the general population, resistance training is beneficial for individuals with coexisting physical conditions, and low-intensity exercises such as yoga and Tai Chi are suitable for pregnant women, the elderly, or postoperative recovery patients. Given its good safety profile and broad applicability, moderate exercise should be considered a first-line treatment for mild anxiety and an adjunctive intervention for moderate to severe anxiety. Future research should further clarify the mechanistic differences between various exercise modalities and promote the development of individualized exercise prescriptions.

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Parkinson's disease(PD)is the second most common neurodegenerative disease that affects movement and cognitive function,resulting from the loss of the neurotransmitter dopamine due to the death of dopaminergic neurons.It affects nearly one million people in the United States and 8.5 million worldwide.While there are some pharmacological and surgical options available,they only provide symptomatic relief,as there is currently no cure for PD.In contrast,exercise training,a non-pharmacological intervention,has emerged as a powerful strategy to enhance the psychological,cognitive,and physiological(motor)impairments associated with PD.Given that the beneficial effects of exercise differ based on the intensity and type of training,gaining a thorough understanding of the molecular mechanisms underlying exercise-induced protection is crucial for developing innovative therapies that improve the quality of life for PD patients around the globe.This review discusses PD pathogenesis and pathophysiology and provides recent clinical evidence of neuroprotective benefits from various exercise modalities and intensity.Furthermore,the molecular mechanisms of exercise in PD pathogenesis(e.g.,modulations on neurotrophic factors,oxidative stress,mitochondria dysfunction,endoplasmic reticulum stress,and autophagy)will be emphasized.

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Resistance exercise has been confirmed to be important for maintaining muscle mass and function.However,despite considerable experimental studies,the underlying mechanisms still requires further investigation to be elucidated.Sestrin1 is a stress-inducible protein strongly associated with the occurrence and development of skeletal muscle dysfunction.Besides,oxidative stress is believed to be a major pathogenic mechanism in the development of skeletal muscle atrophy,whereas regular exercise training induces the endogenous antioxidative system and protects the body against adverse effects of oxidative stress.Nevertheless,whether Sestrin1 is involved in the amelioration of resistance exercise on muscle atrophy and the role of its antioxidant function in this process remains unknown.Here we show that six-week resistance exercise training significantly improved muscle function,muscle mass,and oxidative damage and maintained the level of Sestrin1 in dexamethasone-treated C57BL/6J mice.Mechanistically,Sestrin1 overexpression rescued protein degradation and oxidative stress in atrophied myotubes.Furthermore,an emerging regulator of cellular defense against toxic and oxidative insults,nuclear factor erythroid2–related factor 2(Nrf2)controls the basal and induced expression of an array of antioxidant response element–dependent genes to regulate the pathophysiological outcomes of oxidant exposure.In this study,we found that Nrf2 is a target of Sestrin1,and Nrf2 nuclear translocation is facilitated by Sestrin1.ML385(an Nrf2 inhibitor)treatment mitigated the regulatory effects of overexpression-Sestrin1.Therefore,Sestrin1 was involved in the process of resistance exercise against skeletal muscle atrophy,which may be closely related to its antioxidant capacity,revealing a potential therapeutic strategy for reducing the loss of skeletal muscle.
文摘Background: We monitored changes in salivary creatine pre-and post-high-intensity exercise in young adults while also investigating the potential correlation between salivary and serum creatine levels.Method: Saliva and serum samples were collected before and immediately after an incremental running-toexhaustion treadmill test in fifteen young adults(mean age [23.9 ± 2.9] years, eight females), with samples analyzed for guanidinoacetic acid, creatine, and creatinine using a liquid chromatography–tandem mass spectrometry method.Results: Following exercise, there was a substantial elevation in salivary creatine levels from(17.5 ± 14.2)μmol·L^(-1) to(43.6 ± 30.4) μmol·L^(-1)(p < 0.001), coupled with a significant increase in salivary creatinine from(11.3 ± 5.8) μmol·L^(-1) to(17.0 ± 9.3) μmol·L^(-1)(p = 0.04). In contrast, serum creatine levels were unaffected by exercise(p = 0.80), while creatinine levels exhibited a strong tendency to decrease post-exercise(from [81.8 ±17.5] μmol·L^(-1) to [73.1 ± 11.6] μmol·L^(-1);p = 0.06). A comparison of the slopes of the two regression lines(saliva vs. serum) revealed significant differences for both creatine(p = 0.01) and creatinine(p = 0.03).Conclusions: The above findings suggest a potential difference in the dynamics of creatine metabolites in these two bodily fluids, both pre and post-exercise.

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Growing evidence suggests that exercise can provide neuroprotection by improving mitochondrial quality control(MQC)on the aged brain.Adenosine 5′-monophosphate(AMP)-activated protein kinase(AMPK)signaling responsiveness declines with aging.However,whether AMPK plays a role in the exercise-mediated improvement of memory and MQC in the aged hippocampus remains to be established.5-Aminoimidazole 4-carboxamide ribonucleoside(AICAR),a pharmacological agonist of AMPK,has been proposed to be an exercise mimetic recently.However,it has not been clarified whether AICAR could mimic the effects of exercise on the aged hippocampus through improvement of MQC.In this study,AICAR(AMPK agonist)and Compound C(AMPK inhibitor)were used to investigate if AMPK plays a key role in exercise-induced improvement of MQC and if AICAR could act as an exercise mimetic through improvement of MQC in aged hippocampus.Both exercise and AICAR improved the memory of aged mice and increased AMPK phosphorylation in the aged hippocampus.Exercise,but not AICAR,improved mitochondrial respiratory function in the aged hippocampus and increased the microtubule associated protein 1 light chain 3(LC3)-II/LC3-I ratio and the protein expression of LC3-II and autophagy related protein 7(ATG7)in the lysate of whole hippocampal tissue.Both exercise and AICAR increased the ratio of LC3-II/LC3-I and the protein expression of LC3-II in the mitochondrial fractions of the hippocampus.Regarding mitochondrial dynamics,neither exercise training nor AICAR changed the protein level of mitofusin 2(Mfn2).Exercise,but not AICAR,increased the protein level of dynamin-related protein 1(Drp1).Furthermore,both exercise training and AICAR increased the protein level of peroxisome proliferator-activated receptorγcoactivator 1α(PGC-1α),a modulator of mitochondrial biogenesis.Compound C abolished the exercise-induced effects on memory in aged mice,AMPK phosphorylation,autophagy,mitophagy,and mitochondrial fission in the aged hippocampus.However,Compound C did not reverse the exercise-induced increase in PGC-1αprotein levels in the aged hippocampus.Our data provide evidence that AMPK plays an important role in the exercise-induced improvement of memory and MQC in the hippocampus of aged mice.Importantly,we demonstrated for the first time that AICAR could partially mimetic the beneficial effects of endurance exercise on memory and MQC in the hippocampus of aged mice,and thus may be a promising exercise mimetic for counteracting brain aging.
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.
