The participation of multidisciplinary health focuses on weight loss, freely and spontaneously, or on the indication of bariatric surgery. We know how difficult it is to lose weight. In order to achieve successful procedures, we recommend the “Obese Workshop” or pre- and post-surgical follow-ups close to the patients, with a view to avoiding recurrences or the “accordion effect” (very common), which can interfere with the Body Mass Index (BMI). Everyone, males and females, complained of tiredness and the impossibility of any physical exercise, even the lightest and simplest to be performed, in addition to the fact that they cannot attend gyms and are unable to open a simple door handle.展开更多

Furthermore, studies indicate that physical exercise as an adjuvant can enhance the effects of medication in the treatment of ADHD. Aerobic and coordinative exercises improve executive functioning through their effect on neurocognitive domains that are implicated in ADHD. It is postulated that through their specific modus operandi, aerobic exercise, by raising cortical arousal levels, improves impaired alerting functions whereas coordinative exercises improve the regulation of inhibitory control through the involvement of a higher variety of frontal-dependent cognitive processes. The increasing use of routine neurocognitive testing with continuous performance tests (CPT), such as the QbTest, at clinical assessments for ADHD allows for an innovative approach to identify the assessment impairments in alerting function and inhibition control that are related to ADHD and accordingly choose aerobic or coordinative physical exercise in a more targeted fashion.展开更多

METHODS: A Swedish population-based cross-sectional survey was conducted. Participants aged 40-79 years were randomly selected from the Swedish Registry of the Total Population. Data on physical activity, GERD, body mass index (BMI) and the covariates age, gender, comorbidity, education, sleeping problems, and tobacco smoking were obtained using validated questionnaires. GERD was self-reported and defined as heartburn or regurgitation at least once weekly, and having at least moderate problems from such symptoms. Frequency of physical activity was categorized into three groups: (1) "high" (several times/week); (2) "intermediate" (approximately once weekly); and (3) "low" (1-3 times/mo or less). Analyses were stratified for participants with "normal weight" (BMI < 25 kg/m 2 ), "overweight" (BMI 25 to ≤ 30 kg/m 2 ) and "obese" (BMI > 30 kg/m 2 ). Multivariate logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for potential confounding by covariates. RESULTS: Of 6969 eligible and randomly selected individuals, 4910 (70.5%) participated. High frequency of physical activity was reported by 2463 (50%) participants, GERD was identified in 472 (10%) participants, and obesity was found in 680 (14%). There were 226 (5%) individuals with missing information about BMI. Normal weight, overweight and obese participants were similar regarding distribution of gender and tobacco smoking status, while obese participants were on average slightly older, had fewer years of education, more comorbidity, slightly more sleeping problems, lower frequency of physical activity, and higher occurrence of GERD. Among the 2146 normal-weight participants, crude point estimates indicated a decreased risk of GERD among individuals with high frequency of physical activity (OR: 0.59, 95% CI: 0.39-0.89), compared to low frequency of physical activity. However, after adjustment for potential confounding factors, neither intermediate (OR: 1.30, 95% CI: 0.75-2.26) nor high (OR: 0.99, 95% CI: 0.62-1.60) frequency of physical activity was followed by decreased risk of GERD. Sleeping problems and high comorbidity were identified as potential confounders. Among the 1859 overweight participants, crude point estimates indicated no increased or decreased risk of GERD among individuals with intermediate or high frequency of physical activity, compared to low frequency. After adjustment for confounding, neither intermediate (OR: 0.75, 95% CI: 0.46-1.22) nor high frequency of physical activity were followed by increased or decreased risk of GERD compared to low frequency among nonobese participants. Sleeping problems and high comorbidity were identified as potential confounders for overweight participants. In obese individuals, crude ORs were similar to the adjusted ORs and no particular confounding factors were identified. Intermediate frequency of physical activity was associated with a decreased occurrence of GERD compared to low frequency of physical activity (adjusted OR: 0.41, 95% CI: 0.22-0.77). CONCLUSION: Intermediate frequency of physical activity might decrease the risk of GERD among obese individuals, while no influence of physical activity on GERD was found in non-obese people.展开更多

Physical exercise has been long recog- nized for its therapeutic effects on depressive disorders, although knowledge of the underlying mechanisms remains limited. Suppressed hippocampal neurogenesis in adult brains has been regarded, at least partly, contributive to depression, whereas physical exercise that restores neuro- genesis accordingly exerts the anti-depressive action. Several recent publications have suggested the potential role of adiponectin, a protein hormone secreted by peripheral mature adipocytes, in mediating physical exercise-triggered enhancement of hippocampal neurogenesis and alleviation of depression. Here, we briefly review these novel findings and discuss the possibility of counter- acting depression by modulating adiponectin signaling in the hippocampus with interventions including physical exercise and administration of pharmacological agents.展开更多

Among the variousmechanisms underlying the association between physical exercise and brain health, recent evidence attests that neurotrophin receptor signalingmay have an important role, because the activation of this pathway leads to growth and differentiation of new neurons and synapses, supportsaxonal and dendritic growth, fosters synaptic plasticity, and preserves survival of existing neurons. In this review of published evidence, we highlightthat a positive relationship exists between physical exercise and circulating brain-derived neurotrophic factor levels and that the postexercisevariation of this molecule is associated with improvement of neurocognitive functioning. Less clear evidence has instead been published forother neurotrophins, such as nerve growth factor, neurotrophin-3, and neurotrophin-4. Overall, promotion of adequate volumes and intensities ofphysical exercise (i.e., approximately 3 months of moderate-intensity aerobic exercise, with 2—3 sessions/week lasting not less than 30 min)may hence be regarded as an inexpensive and safe strategy for boosting brain-derived neurotrophic factor release, thus preserving or restoringcognitive functions.展开更多

A unique and comprehensive approach is proposed to perform physical exercise risk evaluation (PERE), in which personalized factors are deterrrdned basing on grey correlation analysis, analytic hierarchy process (AHP) method is used to structure the large numbers of risk factors, and fuzzy comprehensive evaluation (FCE) is applied to fuzzify the factors and compute the exercise risk level. Finally, an actual calculation example is used to verify the feasibility of the method.展开更多

Zn^2+ metabolism in the mossy fiber pathway, and Zn^2+ accumulation in presynaptic membrane vesicles, are dependent on zinc transporter 1 (ZnT1) and glutamate receptor subunit 2 (GluR2). OBJECTIVE: To investigate the effects of long-term recurrent neonatal seizure, in the presence and absence of physical exercise, on the developmental expression of hippocampal zinc transporter 1 (ZnT1) and GluR2, and on cognitive function in rats. DESIGN, TIME AND SETTING: Based on behavioral examination and molecular biological research, a randomized, controlled animal experiment was performed at the Department of Neurobiology, Medical College of Soochow University, between January 2007 and April 2008. MATERIALS: Twenty-one 6-day-old Sprague Dawley rats of either gender were employed in this study. ZnT1 mRNA in situ hybridization kit was provided by Tianjin Haoyang Biological Manufacture Co.,Ltd., China. Rabbit anti-GluR2 was purchased from Santa Cruz Biotech, Inc, USA. METHODS: Rats were randomly divided into a recurrent seizure group (n = 11) and a control group (n = 10). In the recurrent seizure group, 30-minute seizure was induced by flurothyl gas inhalation for a total of 6 consecutive days. Rats from the control group underwent experimental procedures similar to the recurrent seizure group, with the exception of flurothyl gas inhalation. Thirty minutes of treadmill exercise was performed daily by all rats at postnatal days 51–56. MAIN OUTCOME MEASURES: At postnatal day 82, rat hippocampal tissue was harvested for analysis of hippocampal ZnT1 and GluR2 expression by in situ hybridization and immunohistochemistry, respectively. Rat learning and memory capabilities were examined using the Y-maze test. RESULTS: In the recurrent seizure group, the gray scale value of ZnT1 in situ hybridization positive neurons in the hippocampal CA3 region was significantly greater (P 〈 0.05), while the gray scale value of GluR2 immunoreactive neurons in the hippocampal hilus and dentate gyrus was significantly lower (P 〈 0.05), than in the control group. At postnatal days 29–35, numbers of trials to criteria for successful learning were greater in the recurrent seizure group than in the control group (P 〈 0.05); at postnatal days 61–67, the numbers of trials to criteria for successful learning were similar between the two groups (P 〉 0.05). At postnatal days 29–35 and 61–67, there was no significant difference in memory capability between the recurrent seizure and control groups (P 〉 0.05). CONCLUSION: Physical exercise likely improves the learning deficits caused by recurrent neonatal seizure in rats during brain development by modulating ZnT1 and GluR2 expression.展开更多

An exploratory descriptive design was utilized using the cross-sectional survey with self-reported questionnaires (Demographics, Charlson Comorbidity Index, Exercise Self-Efficacy Scale, Exercise Benefits and Barriers Scale, and Commitment to a Plan for Exercise Scale). A convenience sample of 115 Jordanians with diabetes mellitus was recruited from diabetes outpatient clinics. Participants reported an average number of 3.2 physical activities per week (average of 2.9 hours), with walking being the most common activity. Participant’s body mass index, comorbidity index, and exercise self-efficacy were correlated with both frequency and duration of exercise (r = -0.393, -0.286, 0.219 and -0.272, 0.383, 0.260, respectively). A predictive model of five predictors (age, BMI, CCI, exercise self efficacy, and perceived exercise barriers) that significantly predicted exercise duration (R<sup>2</sup> = 0.34, F = 9.14, P < 0.000) was found. Diabetic patients were found to exercise less than optimum. Illness itself was not a cause of not exercising compared to lack of time and desire. Factors that can enhance or inhibit participants’ engagement in exercise should be included in designing tailored exercise educational programs.展开更多

The effects of physical exercises combined with a low-calorie diet on weight loss, body composition, lipoproteins profile, and physical fitness had been well described. However, Central Africa’s studies investigating these kinds of diets and exercise regimens are lacking. Objective. To investigate the effects of adding 14-weeks exercises to a hypocaloric diet on changes in body composition, lipoproteins concentrations, and physical capacities in obese Congolese women. Population and Methods. In total, 34 obese women aged 30 - 39 years (mean age: 33.7 ± 2.4 years) assigned to 14-weeks training program and low energy ketogenic diet. Body composition was assessed using classic methods and impedancemetry. Fasting plasma glucose (FPG) and fasting serum insulin were assessing using enzymatic colorimetric and radioim-munoradiometric methods. HOMA-IR and lipoproteins concentrations were assessed using standardized laboratory methods. VO2peak was measured on a treadmill during a progressive exercise test. Speed, cadence and stride length were measured along the 10-m level walkway. Muscular endurance was measured using the tests of sit-up and inflections-extensions of elbows. All the variables of the study were assessed at the beginning, in the 7-weeks, and in the 14-weeks of training methods. Results. Declines in body weight (16%), percent fat (12.1%), fat weight (26.4%), abdominal fat (34.2%), and waist circumference (10.4%) were found. A significant decrease in FPG (13%), fasting serum insulin (60.9%), HOMA-IR (64.7%), total cholesterol (12.2%), LDL-cholesterol (20.3%), triglycerides (92.8%), and VLDL-triglycerides (17.5%) was shown. In contrast, significant increase in HDL-cholesterol (27.13%) was found. The peak oxygen consumption VO2peak relative to body weight improved more in the 14-weeks training program (13.4%). Obese women exhibited higher values in the 14-weeks training program for speed gait (16.5%), cadence (9.1%), and stride length (15.7%) during normal walk and rapid walk. Weight loss combined with a low-calorie diet and 14-weeks training program improved significantly muscular endurance capacities. Conclusion. Exercise added to hypocaloric diet leads to decreases in body composition, to improve in insulin sensitivity, to enhancement of VO2peak and functional fitness. This may be helpful for the treatment of the metabolic complications of abdominal obesity.展开更多

Methods We selected 16 untrained female students in university and let them had the same amount of exercise for 8 weeks. After that, we collected the cycle blood at the time point or before exercise, the end of exercise and 1 hour after exercise at the end or the 0,first, 2 nd, 4 nd, 6 nd and 8 nd week respectively, so as to de- termine its stimuli index (SI) by MTT method. Results In the different time sect, such as the early stage or exer- cise, quiet condition,as soon as the end of exercise and 1 hour after exercise, we found that the SI were obviousIy low- er than that or normal (P<0.05),especially in the time sect of the end or exercise. Continuing to 4 weeks,the func- tion of T lymphocytes restored gradualy and it lasted to the 8th week, the SI in quiet condition and 1 hour after exer- cise had restored to normal (P>0.05),but in the end or exercise, it still was low,however. the extent of the cases se- lected was in a condition or acute excitability. Conclusion As the bodies adapting to the exercise, the function of T lymphocytes restored slowly and the rate increased faster and faster.展开更多

The American Diabetes Association regards the effectiveness of glycemic control and lifestyle modification therapies on diabetic neuropathies as inconclusive. The objective of this research was to determine if and how physical exercise influences distal symmetric polyneuropathic severity in type 2 diabetes patients. Embase, MEDLINE, and Google Scholar were searched to collect randomized and controlled studies published between January 1, 2012 and April 20, 2020. Titles had to mention diabetes, physical exercise of any type or lifestyle interventions in general, and neuropathy. Abstracts had to indicate satisfaction of PICOS criteria, whereas full-text reviews had to be fully confirmatory. Extracted data was thematically synthesized based primarily on relationships between exercise interventions and effects on distal symmetric polyneuropathic severity outcomes in type 2 diabetes patients. Qualitative analysis scoring criteria objectively mirrored PICO except for the bias and limitation score component, which assessed common markers of validity for randomized trials (as specified in the PRISMA statement). Database searches yielded 379 unique records, 15 of which passed eligibility screening. Thematic synthesis supported exercise as an ameliorative treatment of type 2 diabetes distal symmetric polyneuropathy through improved Michigan Diabetic Neuropathy Scores and increased sural sensory nerve conduction velocity, though efficacy may be limited by neuropathic severity. This is the first systematic review to acquire these results, and to do so within the context of neuropathic severity.

The p53 gene is a tumor suppressor gene found in many malignant and benign tumors;this has the primary function of keeping cells at rest after damaging to DNA. The p53 acts in the maintenance of cellular homeostasis, mainly through autophagy, playing a role in cell cycle arrest, when necessary, thus avoiding mutated DNA replication. When in the oncogenic environment in many cases it is mutated, losing much of its efficiency allowing tumor development. Studies show that exercise can in the regular part of its pro-autophagic function even in the oncology setting. Stimuli of moderate-intensity aerobic and predominance of submaximal seem to trigger the protective function of p53 in various cancer settings. Among the many changes that these pathology triggers were the objective of this mini review is to relate the changes that exercise generates in p53 protein functions and their possible influence on tumor cells.展开更多

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.

文摘AIM: To clarify the association between physical activity and gastroesophageal reflux disease (GERD) in nonobese and obese people. METHODS: A Swedish population-based cross-sectional survey was conducted. Participants aged 40-79 years were randomly selected from the Swedish Registry of the Total Population. Data on physical activity, GERD, body mass index (BMI) and the covariates age, gender, comorbidity, education, sleeping problems, and tobacco smoking were obtained using validated questionnaires. GERD was self-reported and defined as heartburn or regurgitation at least once weekly, and having at least moderate problems from such symptoms. Frequency of physical activity was categorized into three groups: (1) "high" (several times/week); (2) "intermediate" (approximately once weekly); and (3) "low" (1-3 times/mo or less). Analyses were stratified for participants with "normal weight" (BMI < 25 kg/m 2 ), "overweight" (BMI 25 to ≤ 30 kg/m 2 ) and "obese" (BMI > 30 kg/m 2 ). Multivariate logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for potential confounding by covariates. RESULTS: Of 6969 eligible and randomly selected individuals, 4910 (70.5%) participated. High frequency of physical activity was reported by 2463 (50%) participants, GERD was identified in 472 (10%) participants, and obesity was found in 680 (14%). There were 226 (5%) individuals with missing information about BMI. Normal weight, overweight and obese participants were similar regarding distribution of gender and tobacco smoking status, while obese participants were on average slightly older, had fewer years of education, more comorbidity, slightly more sleeping problems, lower frequency of physical activity, and higher occurrence of GERD. Among the 2146 normal-weight participants, crude point estimates indicated a decreased risk of GERD among individuals with high frequency of physical activity (OR: 0.59, 95% CI: 0.39-0.89), compared to low frequency of physical activity. However, after adjustment for potential confounding factors, neither intermediate (OR: 1.30, 95% CI: 0.75-2.26) nor high (OR: 0.99, 95% CI: 0.62-1.60) frequency of physical activity was followed by decreased risk of GERD. Sleeping problems and high comorbidity were identified as potential confounders. Among the 1859 overweight participants, crude point estimates indicated no increased or decreased risk of GERD among individuals with intermediate or high frequency of physical activity, compared to low frequency. After adjustment for confounding, neither intermediate (OR: 0.75, 95% CI: 0.46-1.22) nor high frequency of physical activity were followed by increased or decreased risk of GERD compared to low frequency among nonobese participants. Sleeping problems and high comorbidity were identified as potential confounders for overweight participants. In obese individuals, crude ORs were similar to the adjusted ORs and no particular confounding factors were identified. Intermediate frequency of physical activity was associated with a decreased occurrence of GERD compared to low frequency of physical activity (adjusted OR: 0.41, 95% CI: 0.22-0.77). CONCLUSION: Intermediate frequency of physical activity might decrease the risk of GERD among obese individuals, while no influence of physical activity on GERD was found in non-obese people.

文摘Psychological depression is drawing accumulating attention nowadays, due to the skyrocketing incidence worldwide and the enormous burdens it incurs. Physical exercise has been long recog- nized for its therapeutic effects on depressive disorders, although knowledge of the underlying mechanisms remains limited. Suppressed hippocampal neurogenesis in adult brains has been regarded, at least partly, contributive to depression, whereas physical exercise that restores neuro- genesis accordingly exerts the anti-depressive action. Several recent publications have suggested the potential role of adiponectin, a protein hormone secreted by peripheral mature adipocytes, in mediating physical exercise-triggered enhancement of hippocampal neurogenesis and alleviation of depression. Here, we briefly review these novel findings and discuss the possibility of counter- acting depression by modulating adiponectin signaling in the hippocampus with interventions including physical exercise and administration of pharmacological agents.
文摘Exercise can enhance motivation to change lifestyle behaviors,improve aerobic fitness,improve physical function,control fatigue,and enhance quality of life.Studies have demonstrated the benefits to be gained from physical exercise,highlighting the importance of popularizing the concept of physical exercise for individuals and making professional exercise-treatment programs available to patients with cancer.However,the correlation between physical exercise and carcinogenesis is easily overlooked,and exercise interventions are not routinely provided to patients with cancer,especially those with advanced cancer.In this article,we present a literature review of the effects of exercise on cancer development and progression and give recent evidence for the type of exercise best suited for different types of cancer and in different disease stages.Moreover,the molecular mechanisms about regulating metabolism and systemic immune function in cancer are summarized and discussed.In conclusion,physical exercise should be considered as an important intervention for preventing and treating cancer and its complications.

文摘The many important benefits of physical exercise also encompass maintenance or improvement of cognitive functions. Among the variousmechanisms underlying the association between physical exercise and brain health, recent evidence attests that neurotrophin receptor signalingmay have an important role, because the activation of this pathway leads to growth and differentiation of new neurons and synapses, supportsaxonal and dendritic growth, fosters synaptic plasticity, and preserves survival of existing neurons. In this review of published evidence, we highlightthat a positive relationship exists between physical exercise and circulating brain-derived neurotrophic factor levels and that the postexercisevariation of this molecule is associated with improvement of neurocognitive functioning. Less clear evidence has instead been published forother neurotrophins, such as nerve growth factor, neurotrophin-3, and neurotrophin-4. Overall, promotion of adequate volumes and intensities ofphysical exercise (i.e., approximately 3 months of moderate-intensity aerobic exercise, with 2—3 sessions/week lasting not less than 30 min)may hence be regarded as an inexpensive and safe strategy for boosting brain-derived neurotrophic factor release, thus preserving or restoringcognitive functions.

文摘Exercise is a highly proven and beneficial health promotion modality, But it is very difficult to determine whether the person during exercise is safe. A unique and comprehensive approach is proposed to perform physical exercise risk evaluation (PERE), in which personalized factors are deterrrdned basing on grey correlation analysis, analytic hierarchy process (AHP) method is used to structure the large numbers of risk factors, and fuzzy comprehensive evaluation (FCE) is applied to fuzzify the factors and compute the exercise risk level. Finally, an actual calculation example is used to verify the feasibility of the method.

文摘BACKGROUND: Developmental seizures are pathologically characterized by regenerative sprouting of hippocampal mossy fibers rich in Zn^2+. Zn^2+ metabolism in the mossy fiber pathway, and Zn^2+ accumulation in presynaptic membrane vesicles, are dependent on zinc transporter 1 (ZnT1) and glutamate receptor subunit 2 (GluR2). OBJECTIVE: To investigate the effects of long-term recurrent neonatal seizure, in the presence and absence of physical exercise, on the developmental expression of hippocampal zinc transporter 1 (ZnT1) and GluR2, and on cognitive function in rats. DESIGN, TIME AND SETTING: Based on behavioral examination and molecular biological research, a randomized, controlled animal experiment was performed at the Department of Neurobiology, Medical College of Soochow University, between January 2007 and April 2008. MATERIALS: Twenty-one 6-day-old Sprague Dawley rats of either gender were employed in this study. ZnT1 mRNA in situ hybridization kit was provided by Tianjin Haoyang Biological Manufacture Co.,Ltd., China. Rabbit anti-GluR2 was purchased from Santa Cruz Biotech, Inc, USA. METHODS: Rats were randomly divided into a recurrent seizure group (n = 11) and a control group (n = 10). In the recurrent seizure group, 30-minute seizure was induced by flurothyl gas inhalation for a total of 6 consecutive days. Rats from the control group underwent experimental procedures similar to the recurrent seizure group, with the exception of flurothyl gas inhalation. Thirty minutes of treadmill exercise was performed daily by all rats at postnatal days 51–56. MAIN OUTCOME MEASURES: At postnatal day 82, rat hippocampal tissue was harvested for analysis of hippocampal ZnT1 and GluR2 expression by in situ hybridization and immunohistochemistry, respectively. Rat learning and memory capabilities were examined using the Y-maze test. RESULTS: In the recurrent seizure group, the gray scale value of ZnT1 in situ hybridization positive neurons in the hippocampal CA3 region was significantly greater (P 〈 0.05), while the gray scale value of GluR2 immunoreactive neurons in the hippocampal hilus and dentate gyrus was significantly lower (P 〈 0.05), than in the control group. At postnatal days 29–35, numbers of trials to criteria for successful learning were greater in the recurrent seizure group than in the control group (P 〈 0.05); at postnatal days 61–67, the numbers of trials to criteria for successful learning were similar between the two groups (P 〉 0.05). At postnatal days 29–35 and 61–67, there was no significant difference in memory capability between the recurrent seizure and control groups (P 〉 0.05). CONCLUSION: Physical exercise likely improves the learning deficits caused by recurrent neonatal seizure in rats during brain development by modulating ZnT1 and GluR2 expression.

文摘Aging decreases muscle mass,strength,and functional capacity.High-salt stress seems to promote muscle aging and decrease lifespan.However,exercise delays muscle aging and increases longevity,and it may protect muscle from rapid aging induced by high-salt intake(HSI),but the molecular mechanisms are poorly understood.In this study,the flies were fed a high-salt diet and trained to exercise.Muscle CG2196(salt)gene and dSir2 gene were over-expressed by building mef2-gal4/UAS system.The results showed that both physical exercise and muscle dSir2 gene overexpression prevented HSI-induced and muscle salt overexpression-induced accelerated age-related decline of climbing index,climbing endurance,muscle NAD^(+)level,SOD activity level,dSir2 expression,and dFOXO expression,and they also prevented HSI-induced and muscle salt overexpression-induced accelerated age-related increase in muscle ROS level,MDA level,and salt gene expression.Physical exercise improved lifespan decrease induced by HSI and muscle salt overexpression.Therefore,current results indicated that high-salt stress accelerated muscle aging by decreasing muscular NAD^(+)/dSir2/dFOXO pathway activity and increasing oxidative stress.Physical exercise protected muscle from accelerated aging induced by high-salt stress through activating muscle NAD^(+)/dSir2/dFOXO pathway and enhancing muscle oxidation resistance.The combination of exercise and muscle dSir2 overexpression had the best protective effect on muscle aging and lifespan in flies.

文摘Although employers believe that encouraging and supporting physical exercise activities by purchasing fitness equipment and building sports venues can improve employees’well-being,the utilization rate is rather low.Since most of the evidence of the well-being promotion in the workplace concentrated on the perspectives of organizational factors and psychosocial factors and focused on the reduction of the negative affect of well-being,it is still an open question whether physical exercise has benefits on both negative and positive affect of well-being and who benefits more from physical exercise.Thus,the purpose of this study is to investigate the impact of physical exercise on occupational well-being(job burnout and work engagement)and examine whether effectiveness depends on personality traits.Online questionnaires were distributed.The sample included 671 participants from different enterprises in China.Results showed that the effectiveness of physical exercise was also applicable to well-being in the workplace.Physical exercise was negatively correlated with job burnout and positively correlated with work engagement.The effectiveness was different among employees with different personality traits.Contrary to our expectation,individuals with neuroticism were more likely to improve their work engagement through physical exercise.Extroversion and conscientiousness weakened the benefits of physical exercise.Therefore,differences of effectiveness among different personality traits emphasize the need for a more personalized strategy in physical exercise interventions.
文摘BACKGROUND Physical exercise is an underutilized tool for the management of mental disorders.New technologies have made a breakthrough in health care,and one of its possible applications(apps)could be that of customizing exercise programs for special populations,such as patients with mental disorders.However,the app of the so-called e-health to mental health care is still limited.AIM To know the efficacy of apps to promote physical activity in patients with mental disorders.METHODS We conducted a systematic review of the PubMed and Embase databases with the aim of exploring the use of new technologies for the enhancement of physical exercise in patients with a psychiatric illness.Following the selection process,10 articles were included in the review.RESULTS The most commonly used devices in this type of intervention are wearable devices and web platforms.Good results in terms of effectiveness and acceptability were obtained in most of the studies.CONCLUSION Our findings suggest that the use of new technologies in mental health represents a feasible strategy with great potential in clinical practice.
文摘This study is aimed to investigate exercise behaviors (frequency and duration) among Jordanian diabetic patients, and their correlation with their physical characteristics and perceived exercise benefits and barriers, exercise self efficacy, and exercise planning. An exploratory descriptive design was utilized using the cross-sectional survey with self-reported questionnaires (Demographics, Charlson Comorbidity Index, Exercise Self-Efficacy Scale, Exercise Benefits and Barriers Scale, and Commitment to a Plan for Exercise Scale). A convenience sample of 115 Jordanians with diabetes mellitus was recruited from diabetes outpatient clinics. Participants reported an average number of 3.2 physical activities per week (average of 2.9 hours), with walking being the most common activity. Participant’s body mass index, comorbidity index, and exercise self-efficacy were correlated with both frequency and duration of exercise (r = -0.393, -0.286, 0.219 and -0.272, 0.383, 0.260, respectively). A predictive model of five predictors (age, BMI, CCI, exercise self efficacy, and perceived exercise barriers) that significantly predicted exercise duration (R<sup>2</sup> = 0.34, F = 9.14, P < 0.000) was found. Diabetic patients were found to exercise less than optimum. Illness itself was not a cause of not exercising compared to lack of time and desire. Factors that can enhance or inhibit participants’ engagement in exercise should be included in designing tailored exercise educational programs.
文摘Background. The effects of physical exercises combined with a low-calorie diet on weight loss, body composition, lipoproteins profile, and physical fitness had been well described. However, Central Africa’s studies investigating these kinds of diets and exercise regimens are lacking. Objective. To investigate the effects of adding 14-weeks exercises to a hypocaloric diet on changes in body composition, lipoproteins concentrations, and physical capacities in obese Congolese women. Population and Methods. In total, 34 obese women aged 30 - 39 years (mean age: 33.7 ± 2.4 years) assigned to 14-weeks training program and low energy ketogenic diet. Body composition was assessed using classic methods and impedancemetry. Fasting plasma glucose (FPG) and fasting serum insulin were assessing using enzymatic colorimetric and radioim-munoradiometric methods. HOMA-IR and lipoproteins concentrations were assessed using standardized laboratory methods. VO2peak was measured on a treadmill during a progressive exercise test. Speed, cadence and stride length were measured along the 10-m level walkway. Muscular endurance was measured using the tests of sit-up and inflections-extensions of elbows. All the variables of the study were assessed at the beginning, in the 7-weeks, and in the 14-weeks of training methods. Results. Declines in body weight (16%), percent fat (12.1%), fat weight (26.4%), abdominal fat (34.2%), and waist circumference (10.4%) were found. A significant decrease in FPG (13%), fasting serum insulin (60.9%), HOMA-IR (64.7%), total cholesterol (12.2%), LDL-cholesterol (20.3%), triglycerides (92.8%), and VLDL-triglycerides (17.5%) was shown. In contrast, significant increase in HDL-cholesterol (27.13%) was found. The peak oxygen consumption VO2peak relative to body weight improved more in the 14-weeks training program (13.4%). Obese women exhibited higher values in the 14-weeks training program for speed gait (16.5%), cadence (9.1%), and stride length (15.7%) during normal walk and rapid walk. Weight loss combined with a low-calorie diet and 14-weeks training program improved significantly muscular endurance capacities. Conclusion. Exercise added to hypocaloric diet leads to decreases in body composition, to improve in insulin sensitivity, to enhancement of VO2peak and functional fitness. This may be helpful for the treatment of the metabolic complications of abdominal obesity.

文摘Objective To find out the possible regularity and mechanism of the adaptable change of human be- ing T lymphocytes for physical exercise with oxygen and bring the original data for the Movement of All People Im- proving their Health. Methods We selected 16 untrained female students in university and let them had the same amount of exercise for 8 weeks. After that, we collected the cycle blood at the time point or before exercise, the end of exercise and 1 hour after exercise at the end or the 0,first, 2 nd, 4 nd, 6 nd and 8 nd week respectively, so as to de- termine its stimuli index (SI) by MTT method. Results In the different time sect, such as the early stage or exer- cise, quiet condition,as soon as the end of exercise and 1 hour after exercise, we found that the SI were obviousIy low- er than that or normal (P<0.05),especially in the time sect of the end or exercise. Continuing to 4 weeks,the func- tion of T lymphocytes restored gradualy and it lasted to the 8th week, the SI in quiet condition and 1 hour after exer- cise had restored to normal (P>0.05),but in the end or exercise, it still was low,however. the extent of the cases se- lected was in a condition or acute excitability. Conclusion As the bodies adapting to the exercise, the function of T lymphocytes restored slowly and the rate increased faster and faster.
文摘Pharmaceuticals targeting the pathogenesis of diabetic distal symmetric polyneuropathy have all failed in clinical trials, limiting recourse to palliative treatments. The American Diabetes Association regards the effectiveness of glycemic control and lifestyle modification therapies on diabetic neuropathies as inconclusive. The objective of this research was to determine if and how physical exercise influences distal symmetric polyneuropathic severity in type 2 diabetes patients. Embase, MEDLINE, and Google Scholar were searched to collect randomized and controlled studies published between January 1, 2012 and April 20, 2020. Titles had to mention diabetes, physical exercise of any type or lifestyle interventions in general, and neuropathy. Abstracts had to indicate satisfaction of PICOS criteria, whereas full-text reviews had to be fully confirmatory. Extracted data was thematically synthesized based primarily on relationships between exercise interventions and effects on distal symmetric polyneuropathic severity outcomes in type 2 diabetes patients. Qualitative analysis scoring criteria objectively mirrored PICO except for the bias and limitation score component, which assessed common markers of validity for randomized trials (as specified in the PRISMA statement). Database searches yielded 379 unique records, 15 of which passed eligibility screening. Thematic synthesis supported exercise as an ameliorative treatment of type 2 diabetes distal symmetric polyneuropathy through improved Michigan Diabetic Neuropathy Scores and increased sural sensory nerve conduction velocity, though efficacy may be limited by neuropathic severity. This is the first systematic review to acquire these results, and to do so within the context of neuropathic severity.

文摘Cancer is a global problem that in addition to physical, emotional and physiological causes economic and social impacts. The p53 gene is a tumor suppressor gene found in many malignant and benign tumors;this has the primary function of keeping cells at rest after damaging to DNA. The p53 acts in the maintenance of cellular homeostasis, mainly through autophagy, playing a role in cell cycle arrest, when necessary, thus avoiding mutated DNA replication. When in the oncogenic environment in many cases it is mutated, losing much of its efficiency allowing tumor development. Studies show that exercise can in the regular part of its pro-autophagic function even in the oncology setting. Stimuli of moderate-intensity aerobic and predominance of submaximal seem to trigger the protective function of p53 in various cancer settings. Among the many changes that these pathology triggers were the objective of this mini review is to relate the changes that exercise generates in p53 protein functions and their possible influence on tumor cells.
