ABSTRACT
Acute coronary syndrome (ACS),with increasing mortality year by year,has become a major public health problem in China.Exercise rehabilitation as an important part of the out-of-hospital rehabilitation for the patients with heart diseases can further reduce the mortality of patients on the basis of drug treatment.The available studies have proved that high-intensity interval training (HIIT) is more effective and efficient than moderate-intensity continuous training (MICT) such as walking and jogging on chronic cardiovascular diseases such as heart failure,stable coronary heart disease,and hypertension and has high security.According to the latest research,HIIT can reduce the platelet response,mitigate myocardial ischemia-reperfusion injury,and increase the exercise compliance of ACS patients more significantly than MICT.Moreover,it does not increase the risk of thrombotic adverse events or malignant arrhythmia.Therefore,HIIT is expected to become an important part of exercise prescription in out-of-hospital cardiac rehabilitation strategy for the patients with ACS.

Objective:To explore the effect of moderate intensity physical exercise on depression, anxiety and cognitive function of schizophrenic patients and its possible biochemical mechanism.Methods:Totally 148 patients with schizophrenia who were hospitalized in hospital from March 2019 to March 2021 were randomly divided into control group ( n=75) and exercise group ( n=73). The patients of the two groups were given drug treatment and routine exercise according to clinical practice, and the patients in exercise group were given additional medium-intensity physical exercise.Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to evaluate the poor mental state of the subjects.The verbal fluency task(VFT), digital span test(DST), trail making test-A(TMT-A) and the positive and negative symptom scale (PANSS) were used to evaluate cognitive function.The levels of endocannabinoids (eCBs) receptors were detected by high performance liquid chromatography, and the levels of monoamine neurotransmitters and eCBs in the patients' serum were determined by enzyme-linked immunosorbent assay (ELISA). SPSS 19.0 software was used for statistical analysis.The measurement data between the two groups were compared by t-test and the counting data between the two groups were compared by χ2 test. Results:(1) After effective intervention, the scores of SAS, SDS, TMT-A and PANSS of the two groups were significantly lower than those before intervention, and the difference before and after intervention between the two groups was statistically significant( t=6.00, 6.52, 25.79, 17.03, all P<0.01). The scores of SAS, SDS, TMT-A and PANSS after intervention in the exercise group were significantly lower than those in the control group( t=4.66, 20.88, 6.61, 8.95; all P<0.01). The number of VFT and DST in the two groups after intervention were significantly higher than those before intervention, and the differences before and after intervention between the two groups were statistically significant( t=13.78, 22.76, both P<0.01). After effective intervention, the number of VFT and DST in exercise group were significantly higher than those in the control group( t=5.02, 5.15, both P<0.01). (2) After effective intervention, the contents of monoamine neurotransmitters and eCBs in serum of the two groups were significantly higher than those before intervention, and HVA level ((63.68±6.99) pg/mL), MHPG level ((175.90±16.22) pg/mL), 5-HIAA level ((29.94±4.19) pg/mL) and CBR1 level ((6.70±1.40)μg/L), 2-AG level ((61.90±5.73)pmol/g) and AEA level ((76.48±6.59) pmol/g) in exercise group were significantly higher than those in the control group ((52.97±5.37)pg/mL, (138.50±11.52)pg/mL, (23.87±3.15)pg/mL, (5.71±1.29)μg/L, (52.13±5.14)pmol/g, (67.66±5.88)pmol/g)( t=10.43, 16.21, 10.91, 8.65, all P<0.01). Conclusion:Moderate intensity physical exercise can significantly improve their depression, anxiety and cognitive function, which may be related to regulating the levels of ECBS and their receptors in patients with chronic schizophrenia to increase monoamine neurotransmitters.

The moderate intensity of exercise can affect cancer growth, but how the role it to p53 mutant is not clear. This research proved the expression of p53 mutant in Mus musculus by moderate intensity of exercise. Method: Eighteen animals, were divided into three groups namely, group A, injected by oleum olivarium in the upper buccal mucosa and not given moderate intensity of exercise and benzopyrene; group B, injected benzopyrenes in the same regio, not given moderate intensity of exercise; group C injected benzopyrenes in same region, given moderate intensity of exercise. Moderate intensity of exercise given 3 times every week for 3 months. Oleum olivarum and benzopyrene injection, was given 3 times every week for 1 month, starting at week 5. At the beginning of the 13th week, a bend was taken in the right upper buccal mucosa, then the tissue was processed, painted by immunohistochemical methods. p53 mutant expression was determined by looking at preparations, using an Olympus light microscope with a magnification of 400x. p53 mutan expression was observed in 10 different visual field, then the mean was taken. Result: There were differences in p53 mutant expression in the three groups (p= 0.000), and the highest expression was in group B. Conclusion: The moderate intensity of exercise could decrease p53 mutant expression on squamous cell epithelial of oral Mus musculus.
ABSTRACT
BACKGROUND: Studies have shown that long-term moderate-intensity regular exercise can Improve the activity of mitochondrial respiratory chain complex enzymes In skeletal muscle cells, thereby Improving their power capability as well as the ability to resist fatigue. OBJECTIVE: To explore the effect of moderate-intensity training on prohibitin (PHB) expression and mitochondrial respiratory function in rat skeletal muscle. METHODS: Thirty-two healthy male Sprague-Dawley rats were randomly divided into two groups: Quiet control group and moderate-intensity training group, each of 16 rats. In the moderate-intensity training group, the treadmill training was performed at a slope of 10°: In the 1st week, running at 10 m/min, 10 minutes per day, 6 days per week; in the 2nd week, running at 15 m/min, increased from 10 minutes per day to 60 minutes per day with an increase of 10 minute per day, 6 days per week; in the 3rd to 8th week, running at 15 m/min, 60 minutes per day, 6 days per week for a total of 8 weeks. Rats were sacrificed at 48 hours after the final experiment, and mitochondria were extracted from skeletal muscle samples. Mitochondrial respiration control rate, adenosine triphosphate content, reactive oxygen species level, complex V activity and PHB1 protein expression were measured. RESULTS AND CONCLUSION: Compared with the quiet control group, in the moderate-intensity training group, mitochondrial respiration control rate in the skeletal muscle increased significantly (P < 0.001), adenosine triphosphate content increased significantly (P < 0.05), reactive oxygen species level decreased significantly (P < 0.001), the activity of complex V was significantly increased (P < 0.05) and PHB1 expression was significantly increased (P < 0.01). The correlation analysis showed that after 8 weeks of moderate-intensity training, the expression of PHB1 in the skeletal muscle of rats was positively correlated with adenosine triphosphate content and complex V activity, and negatively correlated with reactive oxygen species level. Therefore, moderate-intensity training improves mitochondrial oxidative phosphorylation, effectively maintains mitochondrial membrane structure and enhances mitochondrial respiratory function by increasing the expression of PHB1.
ABSTRACT
BACKGROUND: Diabetes-induced liver damage is easy to be ignored in the early stage. Exercise therapy can increase the sensitivity of insulin, which is an important means of prevention and treatment of diabetes. OBJECTIVE: To explore the effect of moderate intensity exercise intervention on liver injury during the occurrence of diabetes mellitus. METHODS: The experimental protocol was approved by the Laboratory Animal Care Ethics Committee of Wuhan Sports University. Thirty SPF Sprague-Dawley rats were divided into three groups: normal control group, diabetic control group and diabetic exercise intervention group. Normal control group was fed with normal diet, with no exercise. Diabetes control group was fed with high sugar and high fat diet for 8 weeks, followed by a small dose of streptozotocin (30 mg/kg) injected intraperitoneally, with o exercise. Diabetes exercise intervention group was fed and injected in the same way as diabetes control group, and at the same time carried out moderate intensity treadmill training. After 7 days of streptozotocin injection, hematoxylin-eosin and Masson staining were used to observe the cell morphology, the expression of α-smooth muscle actin was observed by immunohistochemistry, and orbital blood samples were collected to detect the concentration of serum type IV collagen using ELISA. RESULTS AND CONCLUSION: Compared with the normal control group, hematoxylin-eosin staining showed that the structure of liver lobule in the diabetic control group was disordered, a large number of fat vacuoles were seen, and the bile duct in the portal area was obviously proliferated; Masson staining that there were showed fat vacuoles, the structure of liver lobule was seriously damaged, and blue stained collagen fibers were seen in the portal area, and light blue stained collagen fibers were seen between liver cells. The above pathological changes were alleviated in the diabetic exercise intervention group, and the fatty degeneration of liver cells was obviously reduced. The expression of α-smooth muscle actin in the diabetic control group and diabetic exercise intervention group was significantly higher than that in the normal control group (P < 0.05), and that in the diabetic exercise intervention group was significantly lower than that in the diabetic control group (P < 0.05). The level of type IV collagen in the diabetic exercise intervention group was significantly lower than that in the diabetic control group (P < 0.05), to slow down the progress of fibrosis. To conclude, moderate intensity exercise has a good effect on streptozotocin induced liver fibrosis in diabetic rats.
ABSTRACT
It is well known that elderly patients with heart failure have low tolerance to exercise. Heart disease increases the cardiac load and causes severe arrhythmias due to an increase in the afferent stimuli from peripheral tissues such as skeletal muscle and from the sympathetic nervous system. Managing risk during exercise from the peripheral factors is essential to improve the quality of life of this patient population. Previous research involved utilizing high-intensity exercise and invasive methods, but it is necessary to perform at a safe intensity to evaluate the tolerance to exercise during rehabilitation. Therefore, the purpose of this study was to assess the changes in ventilatory and circulatory indices caused by venous ischemia after moderate-intensity exercise. The participants comprised ten healthy men randomly assigned to either a venous blood flow shut off task (task1) or the venous blood flow task (task 2). After 2 days or more the tasks were switched. The protocol was performed using a moderate intensity of rest for a while and performing a 4-min cycling exercise at 200 mmHg while occluding venous outflow of the left leg. Immediately after the termination, both groups took 5 min of rest. Task 1 involved occlusion of the venous outflow using 90 mmHg applied to the left thigh. The result showed that in normal subjects, shutting off the venous blood flow did not change the ventilatory response after moderate-intensity exercise but it changed the circulation index.
ABSTRACT
Resumen El objetivo de esta revisión fue comparar la influencia del entrenamiento por intervalos de alta intensidad (HIIT) con el entrenamiento continuo de moderada intensidad (MICT) sobre la capacidad aeróbica y otras variables relevantes en pacientes con enfermedad de las arterias coronarias (EAC). Realizamos una revisión de estudios sistemáticos y metaanálisis en PubMed hasta el 04 de junio de 2019. Se identificaron un total de 22 artículos, de los cuales 6 se seleccionaron finalmente para esta revisión. La calidad metodológica se evaluó utilizando la herramienta 'Assessment of Multiple Systematic Reviews 2' (AMSTAR-2). Todos los estudios analizaron los efectos del HIIT y MICT en pacientes adultos (rango edad media: 52-76 años). La calidad general de los estudios incluidos fue moderada-alta (AMSTAR-2). El HIIT presentó mayores mejorías sobre el consumo de oxígeno pico y la frecuencia cardíaca pico en comparación al MICT. Esta revisión agrega evidencia adicional que el HIIT presenta mejoras clínicamente significativas sobre la capacidad aeróbica en comparación al MICT. Son necesarios más estudios que permitan establecer conclusiones consistentes de los efectos del HIIT y MICT sobre otras variables relevantes.
Abstract The aim of this review was to compare the influence of high-intensity interval training (HIIT) with moderate-intensity continuous training (MICT) on aerobic capacity and other relevant variables in patients with coronary artery disease (EAC). We reviewed the systematic studies and meta-analysis in PubMed up to June 4th, 2019. A total of 22 articles were identified, of which 6 were selected for this review. The methodological quality was evaluated using the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2) tool. The studies selected analyzed HIIT and MICT effects in adult patients (average ages ranging between 52-76). The overall quality of the included studies was moderate-high (AMSTAR-2). HIIT showed greater improvements over peak oxygen consumption and peak heart rate compared to MICT. This review adds further evidence that HIIT presents clinically significant improvements in aerobic capacity compared to MICT. Further studies are needed to establish consistent conclusions about the effects of HIIT and MICT on other relevant variables.

For the low-risk or stable patients with acute myocardial infarction post percutaneous coronary intervention, compared with moderate-intensity continuous training, high-intensity interval training (HIIT) can better enhance aerobic capacity and protect the cardiovascular system by significantly lowering the inflammatory response, improving endothelial function as well as reversing the progress of ventricular remodeling. HIIT is safety and the patients are more compliant. However, further research is needed on the application of high-risk patients. The standard protocol of HIIT according to the risk stratification also requires further discussion.
ABSTRACT
Objective To explore the heart function and activity of the mitochondrial respiratory chain complex of rats with myocardial hypertrophy induced by the long-term high-intensity interval training(HIIT).Methods Ninety Wistar rats were randomly divided into an HIIT group,a moderate intensity continuous training(MICT) group and a rest control(RC) group,with each group allocated three subgroups according to the observation time(2,6 and 10 weeks),9 groups altogether(n=10 in each group).Each group was given intervention as their names implied.Then,the heart function was measured using the ultrasoundcardiogram,and the body weight as well as the weight of the heart was weighted.The myocardium mitochondria were extracted using the differential centrifugation after homoge nation to detect the activity of the myocardial and mitochondrial citrate synthase (CS),the activities of the respiratory chain complex C Ⅰ ～CⅣ as well as myocardial protein expression of peroxisome proliferator-activated receptor gamma coactivator 1α (PGC-1 α),α-myosin heavy chain (α-MHC),β-MHC,atrial natriuretic factor(ANF) and brain natriuretic peptide(BNP).Results The myocardial hypertrophy was found in HIIT and MICT groups after 1-week and 9-week intervention respectively.At the 2nd and 10th week,no significant differences were found in the heart function,respiratory chain complex activity and protein expression of all three groups(P＞0.05).At the 6th week,the left ventricular ejection fraction,left ventricular fractional shortening,myocardial α-MHC protein expression,and the activities of respiratory chain complex C Ⅰ,C Ⅲ and C Ⅳ of HIIT group were significantly lower while the myocardial β-MHC and BNP protein expression were significantly higher than those of RC and MICT groups(P＜0.05).Conclusion Long-term HIIT but not MICT can induce temporarily pathological myocardial hypertrophy and reduced heart function in Wistar rats,and the mechanism might be related to the downregulation of the myocardial mitochondrial respiratory chain complex activity.
ABSTRACT
Objective To examine the effect of high intensity interval training(HIIT) and moderate intensity continuous training(MICT) on the body component,serum globular adiponectin and skeletal muscle autophagy in C57BL/6 mice.Methods Thirty-six four-week-old C57BL/6 mice were randomly assigned to the control group,MICT group and HIIT groups.The MICT group underwent 60 minutes' aerobic continuous treadmill training at 12 m/min(75％ VO2max) once a day,5 times/week for 6 weeks,while the HIIT group exercised for 1min at 20 m/min(85％ VO2max) followed by 1 min at 8 m/min (50％ VO2max) for alternating 12 cycles.The body weight,body mass index(BMI),total body water,fat mass and citrate synthase(CS) of the quadriceps femoris were measured using ImpediVET experimental animal body composition analyzer.Mice were sacrificed after the analysis,and the level of serum gAcrp30 was detected using the enzyme linked immunosorbent assay.Western blotting was used to detect the expression of pAMPK-Thr172,LC3II/I,Beclin1 and p62 protein in skeletal muscle tissues.Results After 6-week exercise,the body weight of MICT and HIIT mice decreased significantly compared with the sedentary control group.BMI and fat mass of the HIIT group were significantly lower than the control group,but there were no significant differences between the MICT and control groups in the above two measurements.The activity of CS and serum gAcrp30 in HIIT group was significantly higher than the control group.Moreover,the expression of pAMPK-Thr172,LC3II/I and Beclin1 increased significantly in the skeletal muscle after HIIT intervention while the expression of p62 decreased compared with the control group.Conclusion Compared with the MICT,HIIT has more significant effects to reduce body fat and BMI,and activate the autophagy of skeletal muscles.
ABSTRACT
OBJECTIVE:To investigate the effectiveness and economics of 10 mg/d rosuvastatin and 20 mg/d atorvastatin in the treatment of hyperlipidemia (HLP). METHODS:The information of 180 HLP patients selected from Tianmen Municipal First People's Hospital during Mar. 2015-Feb. 2016 were divided into group A and B according to medication regimen,with 90 cases in each group. Group A was given Atorvastatin calcium tablet 20 mg,qd;group B was given Rosuvastatin calcium tablet 10 mg,qd. Treatment course of 2 groups lasted for 8 weeks. Blood lipid indexes before and after treatment,lipid-lowering efficacy,the rate of qualified blood lipid and the occurrence of ADR after treatment were compared between 2 groups. Cost-effectiveness analysis was adopted for economic evaluation. RESULTS:Before treatment,there was no statistical significance in the levels of blood lipid in-dexes between 2 groups (P>0.05). After treatment,TC and LDL-C levels of 2 groups were significantly lower than before treat-ment,and those of group B were significantly lower than those of group A,with statistical significance(P0.05). The costs of group A and B were 488.32,436.24 yuan,and cost-effectiveness ratios were 5.63,4.46;incremental cost-effectiveness ratio was -4.69. The plan of group B had cost-effective-ness advantage. The results of cost-effectiveness analysis were supported by sensitivity analysis. CONCLUSIONS:In the view of short-term efficacy,10 mg/d rosuvastatin plan is better than 20 mg/d atorvastatin plan in lowering lipid and has cost-effectiveness advantage,and both have similar safety.
ABSTRACT
To find the relation between exercise and cytokines, we examined the effect of the training intensity on the levels of cytokines, including interferon-gamma (IFN-γ), interlukine-4 (IL-4) and interlukine-4/interferon-gamma ratio (IL-4/IFN-γ ratio) in female Futsal players. Twelve well-trained female college Futsal players aged 19~22 participated in this study. The athletes completed 30-min of running at 60~65% maximal heart rate [moderate-intensity exercise], and 30-min of running at 75~80% maximal heart rate [high-intensity exercise]. peripheral blood samples were collected 24 h before and 24 h and 48 h after each of the exercise bouts. finding showed that The 30-min bout of moderate-intensity exercise induced a significant increase in IFN-γ (p=0.01) and significant decreases in IL-4 (p=0.001) and IL-4/IFN-γ ratio (p=0.003). And also, 30-min of running at 75~80% maximal heart rate induced increase in IFN-γ (p=0.07) and decreased in IL-4 (p=0.01) and IL-4/IFN-γ ratio (p=0.06) that these changes not significantly. In summary, exercise intensity can effect on the magnitude of changes in cytokines. It seems that moderate intensity exercise enhances cytokine pattern in female college Futsal players.

INTRODUÇÃO: Tradicionalmente, os estudos da cinética do consumo de oxigênio são conduzidos a intensidades de exercício baixas, bem distintas daquelas em que o desempenho desportivo acontece. OBJETIVO: Considerando que a magnitude da cinética deste parâmetro fisiológico depende da intensidade a que o esforço é realizado, pretendeu-se com este trabalho comparar a cinética do consumo de oxigênio em 200 m crowl nadados a duas intensidades distintas: moderada e extrema. MÉTODOS: Dez nadadores do sexo masculino, de nível internacional, realizaram dois testes separados: (i) protocolo progressivo e intervalado de7 x200 m, com 30 segundos de intervalo e incrementos de 0,05 m.s-1 para determinação do patamar correspondente ao limiar anaeróbio; e (ii) 200 m à máxima velocidade. Em ambos, realizou-se uma recolha contínua de gases expirados respiração-a-respiração. RESULTADOS: Diferenças significativas foram obtidas na amplitude e constante temporal determinadas nos 200 m nadados à intensidade extrema e moderada, respectivamente: 38,53 ± 5,30 versus 26,32 ± 9,73 ml. kg-1.min-1 e 13,21 ± 5,86 versus 18,89 ± 6,53 s (p ≤ 0,05). Não foram encontradas diferenças no atraso temporal (9,47 ± 6,42 versus 12,36 ± 6,62 s (p ≤ 0,05), à intensidade extrema e moderada, respectivamente. O atraso temporal correlacionou-se negativamente com a constante temporal à intensidade moderada (r = -0,74, p ≤ 0,05). CONCLUSÕES: Ambas as intensidades estudadas foram bem descritas por aproximações mono-exponenciais, tendo-se verificado diferenças significativas entre as mesmas no que concerne à amplitude e constante temporal.
INTRODUCTION: Traditionally, studies regarding oxygen consumption kinetics are conducted at lower intensities, very different from those in which the sports performance occurs. OBJECTIVE: Knowing that the magnitude of this physiological parameter depends on the intensity in which the effort occurs, it was intended with this study compare the oxygen consumption kinetics in the 200 m front crawl at two different intensities: moderate and extreme. METHODS: Ten international male level swimmers two separate tests by 24h: (i) progressive and intermittent protocol of 7 x 200 m, with 30 seconds intervals and with increments of 0.05m.s-1, to determine the anaerobic threshold correspondent step; and, (ii) 200 m at maximal velocity: in both expiratory gases were continuously collected breath-by-breath. RESULTS: Significant differences were obtained between amplitude and time constant determine in the 200 m at extreme and moderate intensities, respectively (38,53 ± 5,30 ml. kg-1.min-1 versus 26,32 ± 9,73 ml. kg-1.min-1 e 13,21 ± 5,86 s versus 18,89 ± 6,53 s (p ≤ 0,05). No differences were found in time delay (9,47 ± 6,42 s versus 12,36 ± 6,62 s, at extreme and moderate intensity, respectively (p ≤ 0.05). A negative correlation between time delay and time constant at the moderate intensity was reported (r = - 0,74, p ≤ 0,05). CONCLUSIONS: Both intensities were well described by double-exponential fittings, and there were significant differences between them in terms of amplitude and time constant.
ABSTRACT
As new physical activity recommendations and guidelines have spread globally since 1996, scrutiny of the evolution of national physical activity recommendations and guidelines for application to the Korean medical field iare needed. Retrieving literatures and electric database confined to aerobic activity of adult. Most findings were based on the results of epidemiological and behavioral studies of physical activity and health. Most national physical activity recommendations and guidelines have a 'physical activity for health' paradigm instead of an 'exercise for fitness' paradigm. Most stressed the health benefits of accumulation of moderate intensity of a wide variety of physical activity and the importance of the total amount rather than the specific frequency, intensity, time, or type of physical activity. Some used scientific health behavior theories. Research-based applications of evidence based physical activity policy to Korean medical practice are suggested. Korean medical field could have initiatives in comprehensive physical activity policy in Korean health promotion if actively adopting the new physical activity for health paradigm.

The purpose of this study was to determine the effects of supine floating on rectal temperature and cardiac autonomic nervous system activity after exercise. Seven healthy males volunteered for this study. Subjects performed supine position for 30 minutes in both control condition (C-condition) and water condition (W-condition) after exercise with a cycle ergometer for 15 minutes. Exercise intensity was high (80%VO<sub>2</sub>max) and moderate (60%VO<sub>2</sub>max). Water temperature was 30 degrees Celsius. Rectal temperature of post exercise showed no significant differences under the W-condition, as compared to the C-condition. Delta rectal temperature (point 0-0 was end of exercise) was significantly reduced (p<0.05) under the W-condition, as compared to the C-condition. Log HF was significantly increased (p<0.05) under the W-condition, as compared to the C-condition. These data suggested that supine floating after high and moderate intensity exercise could promote recovery of rectal temperature and increased in cardiac parasympathetic nervous system activity.
