To investigate this, we compared two physical activity interventions in middle-aged adults. Methods: Using a pragmatic quasi-experimental design, sedentary community dwelling 50 - 65 year olds (n = 2105) were recruited to a non-randomized 6-month community group exercise program (n = 93) or a physiotherapist-led home-based physical activity program (n = 65). The primary outcome was physical activity adherence derived from exercise diaries. Secondary outcomes included the Active Australia Survey, aerobic capacity (step- test), quality of life (SF-12v2), blood pressure, waist circumference, waist-to-hip ratio (WHR) and body mass index. Results: Home-based participants were more likely to be younger, working full-time and not in a relationship (p Thirty-three percent of the group participants attended ≥ 70% of group exercise sessions. Ninety percent of home-based participants received ≥ 4 of the planned 6 telephone support calls. Intention-to-treat analysis found adherence to the physical activity sessions prescribed was the same for both interventions (26% ± 28% vs. 28% ± 35%). Both interventions significantly increased the number of participants achieving self-reported “sufficient” physical activity (p ≤ 0.001) and significantly decreased waist circumference (p < 0.001) and WHR (p 0.05). Conclusion: The physiotherapist- led home-based physical activity program, requiring few resources, appears to have increased the adoption of physical activity and adherence to physical activity program requirements for sedentary middle-aged adults. The home-based program, providing equivalent health benefits to the group exercise program, may be particularly suitable for those not interested in or unable to attend a group exercise program.

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

The second group performed a supervised training program at an adapted physical activitygym (Sgym), including aerobic and resistance training. The outcomes, collected at baseline and at the end of theprograms, included the 6-minute walking test, the peak oxygen consumption (VO_(2)peak) during a treadmill test,the 5-time sit-to-stand test, and blood pressure.RESULTSSeventeen patients agreed to participate and self-selected into the HBex (n = 9) and Sgym (n = 8) groups. Twopatients in the Sgym group dropped out because of familial problems. At baseline, patients in the HBex group weresignificantly older and had lower walking distance, VO_(2)peak, and lower limb strength. Primary outcome changeswere significantly greater in the HBex group than in the Sgym group (52 ± 23 m vs 8 ± 34;P = 0.005). No othersignificant differences between groups were observed. Both groups improved most of the outcomes in the withingroupcomparisons, with significant variations in VO_(2) peak.CONCLUSIONSix-month moderate-intensity supervised or low-intensity home-based training programs effectively improvedexercise capacity in KTRs. Gym-based programs combine aerobic and resistance training;however, in-homewalking may be proposed for frail KTRs.展开更多

文摘Chronic obstructive pulmonary disease(COPD)is a common chronic respiratory disease that severely affects patients’quality of life.Current clinical treatments primarily rely on medication,with limited rehabilitation options and uncertain efficacy.Home-based exercise rehabilitation,as a non-pharmacological therapy,can promote the improvement of respiratory muscle function and cardiopulmonary endurance,exerting a positive preventive effect on COPD.However,due to factors such as the home environment and lack of health knowledge,COPD patients face numerous difficulties in accepting home-based exercise rehabilitation.This article reviews domestic and international research on the feasibility and effectiveness of home-based exercise rehabilitation for COPD,aiming to provide references for medical workers to better implement home-based exercise rehabilitation for COPD,assist patients in performing rehabilitation exercises at home,improve their quality of life,reduce hospitalization rates,and lower medical costs.
文摘Background:Shoulder dysfunction is very common after mastectomy,and there is also less follow-up for physiotherapy services among patients with mastectomy.Objective:A study was conducted to determine the role of nurse-assisted home-based range of motion(ROM)exercises in patients with shoulder dysfunction after mastectomy.Methods:A pre-and post-interventional study design was used to collect data from 30 post-mastectomy patients.The subjects were selected on a voluntary basis.Informed consent was obtained from post-mastectomy patients who were discharged from different oncology hospitals in Pakistan prior to their inclusion in this study.After obtaining a baseline measurement,the patients were supervised with nurse-assisted ROM exercises at home.The nurse-assisted home-based ROM exercise program was designed for such patients,and the patients were followed-up for up to 1 month.The total duration of the study was 1 year from August 2015 to August 2016.Post-intervention measurement was performed at the patients’home.The difference in terms of pain reduction and ROM improvement at the shoulder joint was recorded using goniometric measurements and the 100 mm visual analogue scale(VAS).Results:The mean age of the 30 subjects was 39.83±5.89.The mean ROM of shoulder flexion before the exercise program was 106.03°,which improved to 133.93°after 1 month of the exercise program.The mean ROM of shoulder abduction before treatment was 94.83°,which improved to 127.13°after 1 month of supervised exercise program.The mean ROM of shoulder rotation before the exercise program was 127.53°,which improved to 152.03°after 1 month of the exercise program.Conclusion:The nurse-assisted home-based shoulder ROM exercise program is effective in terms of improving the range of motion and reducing pain at the shoulder joint in post-mastectomy patients.
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Background:Lung cancer is a major public health concern,and postoperative rehabilitation is crucial for patients.With the emergence of neoadjuvant immunotherapy,understanding the home-based rehabilitation needs of postoperative lung cancer patients who have undergone this therapy has become important.Methods:This qualitative study employed grounded theory.Data were collected through face-to-face,in-depth,semi-structured interviews from February to June 2023 with 15 postoperative lung cancer patients who received routine neoadjuvant immunotherapy.Results:Five key themes emerged:(1)Limited exposure to home-based rehabilitation;(2)Unmet demand for home-based rehabilitation;(3)Factors hindering home-based rehabilitation;(4)Specific home-based rehabilitation needs;(5)Recommendations and observations.The findings revealed that patients lack awareness of home-based rehabilitation,have unmet rehabilitation needs,and require timely implementation of such programs to enhance rehabilitation management and quality of life.Conclusion:This study emphasizes the importance of developing and implementing home-based rehabilitation programs for lung cancer patients who have undergone neoadjuvant immunotherapy.These programs should address the identified needs and recommendations to improve rehabilitation outcomes and quality of life.Future efforts should focus on large-scale implementation and evaluation of these programs.
文摘BACKGROUND Rotator cuff tears are a chief cause of shoulder pain and disability,and surgical repair is often required when conservative management fails.As digital health technologies have expanded,especially since the coronavirus disease 2019 pandemic,digitally augmented rehabilitation programs emerged as a potential alternative to conventional physical therapy.AIM To determine if digitally assisted rehabilitation could be as practical,or even more effective,than the traditional methods most patients currently follow.METHODS Six electronic databases,including PubMed,Scopus,Cochrane Library,Google Scholar,EMBASE,and Web of Science,were searched to find articles that compare digital-based rehabilitation and conventional treatment.Outcomes of interest were Disabilities of the Arm,Shoulder and Hand(DASH)score and range of motion.The quality assessment of the included studies was performed using the risk-of-bias tool for randomized trials tool.RESULTS Three randomized controlled trial studies were enrolled in this study,including 195 cases.We did not find any significant differences between the two groups in terms of DASH score,flexion range of motion,and external rotation range of motion.There was a significant difference between the two groups for abduction range of motion.CONCLUSION Digital home-based rehab seems to be a strong alternative to traditional methods,offering similar results for people recovering from rotator cuff surgery.This approach might also make rehab more accessible and engaging for patients.That said,further research is needed to fully understand the potential of digital rehabilitation and ensure it works effectively for everyone.

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Objective:Based on the breathing exercise derived from the self-efficacy theory,this study aims to construct a breathing exercise intervention program according to the conditions of patients with chronic heart failure,to improve their cardiac function,relieve dyspnea,enhance their quality of life,and further enrich the research on the efficacy of respiratory rehabilitation exercises for patients with chronic heart failure.Method:A total of 98 inpatients with chronic heart failure admitted to the hospital from April 2024 to April 2025 were selected and randomly divided into an intervention group and a control group,with 49 patients in each group.The patients in the control group received conventional nursing,while the patients in the intervention group received the breathing exercise intervention program based on the self-efficacy theory in addition to the conventional nursing of the control group,with interventions conducted through guidance,psychological support,health education,and other methods.The conditions of patients in both groups before and after the intervention were observed.Results:After 1 month and 3 months of intervention,in terms of improving the degree of dyspnea in patients of both groups,the main effect of intervention and the time effect on the degree of dyspnea were statistically significant(F=13.948,P<0.001;F=38.423,P<0.001).Moreover,there was an interaction between the time factor and the intervention factor in both groups(F=113.763,P<0.001).In terms of increasing the 6-minute walking distance,the main effect and time effect in both groups were statistically significant(F=7.371,P=0.008;F=459.405,P<0.001),and there was an interaction effect between the time factor and intervention factor in both groups(F=177.180,P<0.001).After 1 month and 3 months of intervention,in terms of improving the level of exercise self-efficacy,the main effect of intervention and the time effect in both groups were statistically significant(F=6.860,P=0.01;F=25.133,P<0.001),and there was an interaction between the time factor and the intervention factor(F=159.576,P<0.05).Conclusion:Breathing exercise based on the self-efficacy theory is helpful to improve the sense of efficacy of patients with chronic heart failure,enable them to persist in breathing exercise for a long time,further alleviate their dyspnea,promote the recovery of cardiopulmonary function,and enhance their quality of life.Breathing exercise based on the self-efficacy theory can be used as a simple,home-based intervention method to provide corresponding help for patients with chronic heart failure during the rehabilitation period.
文摘Objectives: Program method, program deliverer and participant preference may be important factors in increasing physical activity adherence and program effectiveness. To investigate this, we compared two physical activity interventions in middle-aged adults. Methods: Using a pragmatic quasi-experimental design, sedentary community dwelling 50 - 65 year olds (n = 2105) were recruited to a non-randomized 6-month community group exercise program (n = 93) or a physiotherapist-led home-based physical activity program (n = 65). The primary outcome was physical activity adherence derived from exercise diaries. Secondary outcomes included the Active Australia Survey, aerobic capacity (step- test), quality of life (SF-12v2), blood pressure, waist circumference, waist-to-hip ratio (WHR) and body mass index. Results: Home-based participants were more likely to be younger, working full-time and not in a relationship (p Thirty-three percent of the group participants attended ≥ 70% of group exercise sessions. Ninety percent of home-based participants received ≥ 4 of the planned 6 telephone support calls. Intention-to-treat analysis found adherence to the physical activity sessions prescribed was the same for both interventions (26% ± 28% vs. 28% ± 35%). Both interventions significantly increased the number of participants achieving self-reported “sufficient” physical activity (p ≤ 0.001) and significantly decreased waist circumference (p < 0.001) and WHR (p 0.05). Conclusion: The physiotherapist- led home-based physical activity program, requiring few resources, appears to have increased the adoption of physical activity and adherence to physical activity program requirements for sedentary middle-aged adults. The home-based program, providing equivalent health benefits to the group exercise program, may be particularly suitable for those not interested in or unable to attend a group exercise program.

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The addition of sarcomeres in series(sarcomerogenesis)in skeletal muscle has increasingly fascinated exercise scientists in recent years due to its potential to positively impact performance.1,2 In their new review article,Triggering sarcomerogenesis:Examining key stimuli and the role attributed to eccentric training—Historical,systematic,and meta-analytic review,Blazevich et al.3 provide a commendable overview of the history behind this area of research from the 1600s to present.
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BACKGROUND Although the benefits of exercise for kidney transplant recipients(KTRs)have been widely demonstrated,these patients experience several barriers in undertaking a structured exercise program in hospital and non-hospital facilities.AIM To compare the effects of a supervised moderate-intensity gym-based intervention with a home-based low-intensity walking program on exercise capacity in KTRs.METHODS KTRs were asked to choose between two six-month programs.The first group performed a low-intensity interval walking intervention at home-based exercise intervention (HBex). The second group performed a supervised training program at an adapted physical activitygym (Sgym), including aerobic and resistance training. The outcomes, collected at baseline and at the end of theprograms, included the 6-minute walking test, the peak oxygen consumption (VO_(2)peak) during a treadmill test,the 5-time sit-to-stand test, and blood pressure.RESULTSSeventeen patients agreed to participate and self-selected into the HBex (n = 9) and Sgym (n = 8) groups. Twopatients in the Sgym group dropped out because of familial problems. At baseline, patients in the HBex group weresignificantly older and had lower walking distance, VO_(2)peak, and lower limb strength. Primary outcome changeswere significantly greater in the HBex group than in the Sgym group (52 ± 23 m vs 8 ± 34;P = 0.005). No othersignificant differences between groups were observed. Both groups improved most of the outcomes in the withingroupcomparisons, with significant variations in VO_(2) peak.CONCLUSIONSix-month moderate-intensity supervised or low-intensity home-based training programs effectively improvedexercise capacity in KTRs. Gym-based programs combine aerobic and resistance training;however, in-homewalking may be proposed for frail KTRs.

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 Evidence on pre-operative physical activity before hip and knee arthroplasty is limited and heterogeneous.Intervention components and behavior change techniques remain underexplored.This review examined the effectiveness of pre-operative physical activity interventions on patient and surgical outcomes in elective hip and knee arthroplasty up to 12 weeks post-surgery.Methods A systematic search of 8 databases up to August 8,2024 identified randomized controlled trials of physical activity interventions before total hip and knee arthroplasty.Quality of evidence was evaluated with Grading of Recommendations,Assessment,Development and Evaluation framework.Random-effects models were used for meta-analyses.The Template for Intervention Description and Replication(TIDieR)was used for detailing the included interventions.Results Forty trials were included.Significant mean differences in favor of the intervention groups were found at pre-and post-surgery in 4 outcomes:health-related quality of life(Knee pre-surgery standardized mean difference(SMD)=−0.5,95%confidence interval(95%CI):−1.0 to−0.1 and Hip and Knee post-surgery SMD=−0.4,95%CI:−0.6 to−0.1),pain(Hip and Knee pre-surgery SMD=−0.4,95%CI:−0.6 to−0.1 and Knee post-surgery SMD=−0.3,95%CI:−0.6 to−0.1),function(Hip and Knee pre-surgery SMD=−0.5,95%CI:−0.8 to−0.2 and Knee post-surgery SMD=−0.6,95%CI:−1.0 to−0.2),and timed-up-and-go(Hip and Knee MD=−1.2 s,95%CI:−2.0 to−0.3 and Hip and Knee MD=−1.3 s,95%CI:−1.7 to−0.8).Half of the interventions reported over 75%of the TIDieR items,while behavior change techniques reporting was limited.Conclusion Pre-operative exercise improves health-related quality of life,pain,and function pre-and post-surgery in elective hip and knee arthroplasty.Standardized reporting is needed for establishing effective intervention components.
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.
