Resistance exercise preconditioning prevents disuse muscle atrophy by inhibiting apoptosis and protein degradation via SESN2 in C57BL/6J mice

AimTo compare the effects of different exercise preconditioning in the context of skeletal muscle atrophy and to investigate the potential involvement of Sestrin2 (SESN2), a stress-inducible protein that can be regulated by exercise, in exercise preconditioning on preventing disuse muscle atrophy. MethodsEight-week-old male C57BL/6J mice were randomly assigned to sedentary groups (SD), aerobic exercise groups (AE), resistance exercise groups (RE), and combined exercise groups (CE) with or without 7 days of immobilization. The duration of the exercise intervention was 10 weeks. The effects of different exercise preconditioning to prevent muscle atrophy were analyzed by evaluating skeletal muscle function and mass. Additionally, to investigate the potential underlying mechanism of exercise-induced protection of skeletal muscle, wild-type and SESN2‐−/‐− mice were randomly divided into sedentary group and resistance exercise preconditioning group. C2C12 cells were treated with SESN2 adenoviruses and MK2206 (an AKT inhibitor) for 48 h to elucidate the underlined mechanism. ResultsRE was more effective in preserving skeletal muscle function, muscle mass and maintaining skeletal muscle protein homeostasis than AE and CE under immobilized condition. Importantly, exercise performance, muscle mass to body weight ratio, and the cross-sectional area of muscle fibers were significantly lower in SESN2−/− mice than wild-type mice after resistance exercise preconditioning. Mechanistically, the absence of SESN2 led to activation of the ubiquitin-proteasome system and induction of apoptosis. In vitro experiments showed that MK2206 treatment mitigated the regulatory effects of overexpression-SESN2 on protein hydrolysis and apoptosis. ConclusionRE was more effective than AE or CE in preventing disuse muscle atrophy. SESN2 mediated the protective effects of resistance exercise preconditioning on skeletal muscle atrophy.

Effect of Exercise on Fatigue in Patients Receiving Maintenance Hemodialysis Treatment: A Systematic Review and Network Meta-analysis.

This study aimed to evaluate the effect of different exercises for improving fatigue in maintenance hemodialysis patients. PubMed, Embase, Web of Science, Cochrane, PEDro, CNKI, VIP, Wanfang data, CBM, and CINAHL were conducted from the establishment of the database to July 2023. We independently screened the literature, evaluated the quality, analyzed the data using Stata 15.0, and performed subgroup analysis on intervention time and exercise intervention adherence. Twenty-three studies were analyzed, with 1867 patients and nine interventions. Based on the surface under cumulative ranking curves and pairwise comparisons effects, overall long-term, short-term, and exercise intervention adherence >90% effects have all presented that during dialysis aerobic-resistance combined exercise was ranked as the most effective compared with routine care (surface under cumulative ranking curves = 83.9%, standardized mean difference = -1.45, 95% CI = -2.23 to -0.67; surface under cumulative ranking curves = 85.9%, standardized mean difference = -1.38, 95% CI = -2.24 to -0.52; surface under cumulative ranking curves = 86.6%, standardized mean difference = -1.54, 95% CI = -2.58 to -0.49; surface under cumulative ranking curves = 83.6%, standardized mean difference = -1.45, 95% CI = -2.25 to -0.66, respectively), followed by interdialytic period muscle relaxation exercise, interdialytic period aerobic-resistance combined exercise, interdialytic period aerobic exercise, and interdialytic period Baduanjin. Dialysis aerobic-resistance combined exercise may be considered in practice when resources allow. However, high-quality, multicenter, and large-sample randomized control trials must further verify this conclusion.

Exercise-mediated macrophage polarization modulates the targeted therapeutic effect of NAFLD: a review.

This review aims to explore the exercise-mediated hepatic macrophage polarization mechanism and its effect on improving and regulating non-alcoholic fatty liver disease (NAFLD) by analyzing the pathogenesis of NAFLD and the cause of the influence of hepatic macrophage polarization. In addition to exploring the varied effects of different exercise types on macrophage polarization regulation in NAFLD, to provide a direction and basis for the treatment of NAFLD. The research methodology involved a comprehensive search of the PubMed database using specific keywords such as "NAFLD", "macrophage polarization", and "exercise", to retrieve relevant literature published. (1) The main factors inducing NAFLD were high-fat diet, obesity, insulin resistance (IR), changes in gut microbiota, and genetic variation in susceptibility. (2) Drug treatment, nutrient induction, microfactor induction, physiological environment induction, and other factors can induce the polarization of hepatic macrophages and affect NAFLD. (3) Different intensities, types, and frequencies of exercise have different effects on polarization macrophages, and may also differently effects improving liver inflammation, fibrosis, and NAFLD. Curently, regular moderate-intensity aerobic exercise is the most effective therapy for treating NAFLD. Approaches to ameliorate NAFLD with exercise involve strategies to alter macrophage polarization by inhibiting M1 or driving M2 activation. However, research on the different types of exercise-mediated macrophage polarization mechanisms and differences in therapeutic effects is not yet sufficient. Future research is necessary to explore the exact mechanisms and differences in the effects of different exercises on the treatment of NAFLD.

Physical Therapy Interventions in Children With Cerebral Palsy: A Systematic Review.

Cerebral palsy is a group of disorders affecting individuals already from birth. It enormously impacts an individual's physical and emotional life and can bring many challenges to the individual, caregivers, and families. Therefore, it is crucial to investigate interventions that could improve various symptoms in children with cerebral palsy. Our systematic review intends to assess the effect of different exercise and physical therapy interventions in children with cerebral palsy. We used three databases for our article search: PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), and PubMed Central (PMC). The combined number of papers found in all databases was 65,412. We then applied our inclusion and exclusion criteria, filters, key terms, and Medical Subheadings (MeSH). After applying our quality assessment tools, we included nine papers in our systematic review. The studies included in our review used various interventions to assess for improvement in symptoms in individuals with cerebral palsy. Interventions included stretching and resistance exercises, horse riding, biking, core stability exercises, slackline training, a home exercise program using an online tool, sit-to-stand exercise program, and functional training. Many studies have shown that interventions improved symptoms like balance, coordination, gait, and cardiovascular endurance in cerebral palsy. This review suggests that some of the included interventions have great potential to improve the symptoms of cerebral palsy and, therefore, can be a great addition to existing training and rehabilitation programs. Given that studies included a relatively small number of participants and were conducted over a short time, more research with a more significant number of participants over a longer time is necessary.

Effect of different intensity exercises on cardiopulmonary function and quality of life of patients with chronic heart failure : Asystematic review and meta-analysis.

Exercise-based cardiac rehabilitation has positive benefits for patients with chronic heart failure (CHF), but the choice of exercise intensity has been controversial. The aim of this systematic review and meta-analysis was to investigate the effects of different exercise intensities on cardiopulmonary function and quality of life (QoL) of patients with CHF. Randomized controlled trials (RCTs) of different exercise intensities applied to patients with CHF were searched in PubMed, Web of Science, the Cochrane Library, and Embase databases from inception to December 2021. Study selection and data extraction were performed simultaneously by two independent reviewers, using the Physiotherapy Evidence Database Scale (PEDro) for quality assessment of the included literature. The weighted mean differences (WMD) or standardized mean difference (SMD) were calculated by employing afixed or random effects model. Other statistical analyses included subgroup analysis and sensitivity analysis. Quality of evidence was evaluated by the Grade of Recommendation, Assessment, Development, and Evaluation (GRADE) method. Eight RCTs were included. Analyses reported no significant improvement in left ventricular ejection fractions (LVEF; WMD = 0.47, 95% CI [-4.10, 5.03], p = 0.841), peak oxygen uptake (peakVO2) (SMD = 0.38, 95% CI [-0.03, 0.80], p = 0.069) and 6‑min walking distance (6MWD) (WMD = 14.10, 95% CI [-9.51, 37.72], p = 0.242). Exercise interventions of varying intensity produced small-to-moderate beneficial effects on QoL (WMD = -4.99, 95% CI [-8.29, -1.68], p = 0.003), which appeared to be attenuated at long-term follow-up (WMD = 2.12, 95% CI [-2.91, 7.16], p = 0.409). High-intensity exercise does not have asignificant advantage over moderate-intensity exercise in improving cardiopulmonary function and aerobic capacity in patients with CHF. Beneficial changes in QoL from high-intensity exercise also appeared to decrease during long-term follow-up, indicating acumulative effect of the efficacy of high-intensity exercise.

Effects of Exercise and Sports Intervention and the Involvement Level on the Mineral Health of Different Bone Sites in the Leg, Hip, and Spine: A Systematic Review and Meta-Analysis.

The current study analysed whether the osteogenic stimuli of exercises and sports have an independent effect on bone mineral density (BMD). Studies with a design having two different cohorts were searched and selected to distinguish the effect due to long-term involvement (i.e., athletes vs. non-active young with good bone health) and due to the planning of intervention (i.e., pre- vs. post-training) with exercises and sports. Moreover, only studies investigating the bone sites with a body-weight support function (i.e., lower limb, hip, and spine regions) were reviewed, since the osteogenic effects have incongruous results. A meta-analysis was performed following the recommendations of PRISMA. Heterogeneity (I2) was determined by combining Cochran's Q test with the Higgins test, with a significance level of α = 0.05. The studies reporting the effect of involvement in exercise and sports showed high heterogeneity for the lower limb, total hip, and spine (I2 = 90.200%, 93.334%, and 95.168%, respectively, with p < 0.01) and the effect size on sports modalities (Hedge's g = 1.529, 1.652, and 0.417, respectively, with p < 0.05) ranging from moderate to high. In turn, the studies reporting the effect of the intervention planning showed that there was no heterogeneity for the lower limb (I2 = 0.000%, p = 0.999) and spine (I2 = 77.863%, p = 0.000); however, for the hip, it was moderate (I2 = 49.432%, p = 0.054), with a low effect between the pre- and post-training moments presented only for the hip and spine (Hedge's g = 0.313 and 0.353, respectively, with p < 0.05). The current analysis supported the effect of involvement in exercise and sports by evidencing the effect of either weight-bearing or non-weight-bearing movements on BMD at the femoral, pelvic, and lumbar bones sites of the athletes when comparing to non-athletes or non-active peers with healthy bones. Moreover, the effect of different exercise and sports interventions highlighted the alterations in the BMD in the spine bone sites, mainly with long-term protocols (~12 months) planned with a stimulus with high muscle tension. Therefore, exercise and sport (mainly systematic long-term practice) have the potential to increase the BMD of bones with body-weight support beyond the healthy values reached during life phases of youth and adulthood.

Effects of Different Exercises on Physical Function, Dialysis Adequacy, and Health-Related Quality of Life in Maintenance Hemodialysis Patients: A Systematic Review and Network Meta-Analysis

Background: Clinical guidelines recommend exercise training for patients undergoing maintenance hemodialysis (MHD). However, the effectiveness of different types of exercise remains uncertain. Objectives: The aims of the study were to compare and rank the effect of different types of exercise on walking capacity, cardiorespiratory fitness, dialysis adequacy, and health-related quality of life (HRQOL) in patients undergoing MHD. Methods: Eight databases (four English and four Chinese) were searched from inception to January 1, 2022. Randomized controlled trials evaluating the efficacy of different exercises for patients undergoing MHD were included. Two independent reviewers screened the literature, extracted data, assessed the risk of bias, and evaluated the certainty of evidence. A frequentist random-effect network meta-analysis was conducted. Results: Ninety trials with 4,084 participants comparing 15 types of exercise were included, reporting on the six-minute walking test (45 trials), peak oxygen uptake (22 trials), dialysis adequacy (30 trials), and HRQOL (23 trials). Network meta-analysis showed that the most effective intervention for walking capacity was intradialytic aerobic exercise combined with blood flow restriction with a mean difference and 95% confidence interval of 97.35 (11.89–182.81), for peak oxygen uptake it was non-intradialytic combined aerobic and resistance exercise with a value of 4.35 (2.25–6.44), for dialysis adequacy it was intradialytic combined aerobic and resistance exercise with a value of 0.17 (0.06–0.28), for the physical component summary of HRQOL it was intradialytic aerobic exercise with a value of 4.93 (2.31–7.54), and for the mental component summary of HRQOL it was non-intradialytic combined aerobic and resistance exercise with a value of 6.36 (0.45–12.27). Ultimately, intradialytic combined aerobic and resistance exercise could improve all the above outcomes compared to usual care. Conclusions: This study concluded that intradialytic combined aerobic and resistance exercise is optimal for MHD patients due to its significant positive effects on multiple outcomes. Walking capacity can be further enhanced by combining blood flow restriction with exercise. For improving dialysis adequacy, intradialytic exercise proves to be more effective than non-intradialytic exercise. Further well-designed clinical trials are needed to investigate the effects of exercise with varying durations, intensities, and frequencies.

Acute effects of different exercise forms on executive function and the mechanism of cerebral hemodynamics in hospitalized T2DM patients: a within-subject study.

This study aimed to investigate the acute effects of aerobic exercise (AE), resistance exercise (RE), and integrated concurrent exercise (ICE; i.e., AE plus RE) on executive function among hospitalized type 2 diabetes mellitus (T2DM) inpatients, and the mechanism of cerebral hemodynamics. A within-subject design was applied in 30 hospitalized patients with T2DM aged between 45 and 70 years in the Jiangsu Geriatric Hospital, China. The participants were asked to take AE, RE, and ICE for 3 days at 48-h intervals. Three executive function (EF) tests, namely, Stroop, More-odd shifting, and 2-back tests, were applied at baseline and after each exercise. The functional near-infrared spectroscopy brain function imaging system was used to collect cerebral hemodynamic data. The one-way repeated measurement ANOVA was used to explore training effects on each test indicator. Compared with the baseline data, the EF indicators have been improved after both ICE and RE (p < 0.05). Compared with the AE group, the ICE and RE groups have demonstrated significant improvements in inhibition (ICE: MD = - 162.92 ms; RE: MD = -106.86 ms) and conversion functions (ICE: MD = -111.79 ms; RE: MD = -86.95 ms). Based on the cerebral hemodynamic data, the beta values of brain activation in executive function related brain regions increased after three kinds of exercise, the EF improvements after the ICE showed synchronous activation of blood flow in the dorsolateral prefrontal cortex (DLPFC), the frontal polar (FPA) and orbitofrontal cortex (OFC), the improvement of inhibitory function after RE displayed synchronous activation of DLPFC and FPA, and AE mainly activates DLPFC. The HbO2 concentration in the pars triangularis Broca's area increased significantly after AE, but the EF did not improve significantly. The ICE is preferred for the improvements of executive function in T2DM patients, while AE is more conducive to the improvements of refresh function. Moreover, a synergistic mechanism exists between cognitive function and blood flow activation in specific brain regions.

IMPACTO DE DISTINTOS ESPORTES SOBRE AS MASSAS CORPORAIS DE UNIVERSITÁRIAS

ABSTRACT Introduction A healthy body depends on several factors, and physical exercise is one of the main factors. Research results on the physical health of female university students show that although the general health status of Chinese female students is good, the quality of physical performance at university continues to show a slow downward trend. Objective To explore the effects of different exercises on the fat mass and lean weight indices of female university students. Methods 60 female students who participated in aerobics and ball games training in the Physical Education Department of a university were randomly divided into a control group and a training group, with 30 volunteers in each group. The experimental group performed intensive aerobics training and ball training. In contrast, no intervention was performed in the control group, and indicators were collected and analyzed according to current literature. Results After eight weeks of the intervention protocol, the body weight, body fat weight, lean weight, body surface area, and body fat ratio of the control group had no significant changes from the period before the experiment (P &gt; 0.05). In the training group, fat weight decreased significantly (p&lt;0.01), lean mass weight increased significantly (p&lt;0.01), body fat ratio decreased (p&lt;0.01), and body weight and body surface area had no significant changes (p&gt;0.05). PTH and FSH in the training group were significantly higher than in the control group (P &lt; 0.05). As the aerobic exercise level improved in the experimental group, the weight and abdominal skinfold thickness in the exercise group showed a downward trend. Conclusion There is a general correlation between BMI and body fat content and its body distribution in college women. Compared to men, BMI is better suited to describe the fat metabolism of college women. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

A Meta Analysis of Physical Exercise on Improving Lung Function and Quality of Life Among Asthma Patients.

ObjectiveThis paper aims to perform a systematic assessment of the influence of physical exercise on asthma patients and discuss the intervention effects of different exercises on the lung function FEV1 (%pred) and quality of life among asthma patients so as to lay a scientific foundation for improving asthma symptoms.MethodsBoth Chinese and English databases were retrieved, including PubMed, Web of Science, Embase, The Cochrane Library, CBM, CNKI, Wan Fang Data, and VIP, whose retrieval period started from the founding date of each database to 1st, November 2021. Randomized controlled trials (RCT) studying the symptom indicators of asthma patients were collected. Those collected papers were screened according to the Inclusion Criteria and Exclusion Criteria. Then, methodological quality assessments were conducted on the included papers, and combined effect sizes were analyzed by using software ReMan 5.3.5.ResultsThe meta analysis showed that physical exercise could significantly improve lung function FEV1 (%pred) and quality of life score. Trails containing breathing exercise are the main source of heterogeneity, and the subgroup of breathing exercise may have better performance than the subgroup of aerobic exercise in improving FEV1 (%pred).ConclusionPhysical exercise can significantly improve the symptoms and quality of life of asthma patients. Except the breathing exercise that showed heterogeneity, the subgroup of aerobic exercise could improve the capacity of FEV1 (%pred) more effectively, which led to a significant difference in the influence of quality of life. However, with regard to the gymnastic exercise including breathing exercise, there are limited same intervention methods and insufficient same outcome indicators. Therefore, more precise and high-quality researches are needed to make deeper verification in the future.

Establishing minimal clinically important difference for effectiveness of corrective exercises on craniovertebral and shoulder angles among students with forward head posture: a clinical trial study

BackgroundPrevious studies have addressed the effects of different exercises and modalities on forward head posture (FHP), but the minimal clinically important difference (MCID) of the effect of exercises on FHP remains unclear. Therefore, this study aimed to investigate the effects of selective corrective exercises (SCEs) on the craniovertebral angle (CVA) and shoulder angle (SA) in students with FHP and to establish MCID for these angles.MethodsIn this randomized clinical trial study, a total of 103 second-grade male students with FHP were enrolled. Participants were randomly assigned to experimental and control groups. CVA and SA of participants were measured before and after the 8-week selective corrective exercise program (including strengthening and stretching exercises). The photogrammetric method was used to measure CVA and SA. MCID value was calculated for CVA and SA using the distribution method.ResultsThe results showed that there was a significant difference between the experimental and control groups in terms of CVA (F = 89.04, P = 0.005, Effect size = 0.47) and SA (F = 18.83, P = 0.005, Effect size = 0.16). After eight weeks of selective corrective exercises, the MCID values of CVA and SA were 1.40° and 1.34°, respectively.ConclusionThis study revealed that the selective corrective exercises might lead to postural correction of students having FHP problem. Results further indicated that a corrective exercise program would be considered beneficial if it increased CVA and SA values at least 1.40 and 1.34 degrees, respectively.

Validity and Reliability of an Offline Ultrasound Measurement of Bladder Base Displacement in Women.

The effect of different exercises on the position of pelvic organs in women has not been sufficiently assessed. The objective was to analyze the validity and reliability of a new two-dimensional ultrasound algorithm to measure offline the displacement of the bladder base during abdominal exercises. This algorithm could be a useful method to future studies in determine the most appropriate exercises in sports and in rehabilitative program for the pelvic floor in women. All subjects were tested by transverse transabdominal ultrasound. The measurements were conducted offline using a customized code written in MATLAB (Ecolab) for image-processing, and manually on the ultrasound monitor using electronic calipers. The agreement was assessed with a paired t-test, Pearson’s linear correlation coefficient (r), the Lin’s concordance correlation coefficient (CCC), the intraclass correlation coefficient ICC (A,2) and a Bland–Altman plot. The reliability was confirmed by the interdays intra-rater ICC coefficient. The results were that Ecolab and ultrasound transducer measures did not differ statistically (p = 0.246). Furthermore, both methods showed a very strong relationship, and the Ecolab demonstrated to be a valid and reliable method. We concluded that Ecolab seemed to be a valid and reliable tool to assess the effect of abdominal contractions in the female pelvic floor.

Immediate effect of different exercises in the vocal space of women with and without vocal nodules.

To investigate the immediate effect of voiced tongue vibration (VSL), high-resistance straw in the air (CAR), and overarticulation (OA) on the vocal space of vocally healthy women (MVS) and with vocal nodules (MNV). 12 women participated in the MNV and 12 women in the MVS, allocated to perform the vocal exercises of VSL, CAR, and OA. Each participant performed only one of the three proposed exercises, for 5 minutes, preceded and followed by recording a sequence of vehicle sentences for extracting formants (F1 and F2) from the vowel segments [a, i, u]. The vowel space was analyzed through the differences between the measures of the formants of the vowels. we observed a reduction of F1 in the interval [a]-[i] and [i]-[u] and of F2 between the vowels [a]-[u] and [i]-[u] in the MVS, after performing the CAR. In MNV, we observed a reduction of F2 in the interval [a]-[i] after VSL. In the intergroup analysis, there were higher F1 values between the intervals of the vowels [a]-[i] and [i]-[u] in the MVS, before performing the CAR, and after exercise only in the interval [a]-[i]. A higher value of F1 and F2 was observed in the interval between the vowels [i]-[u] in the MNV after VSL. The VSL exercise reduced the vowel space in MNV women. CAR reduced the vocal space of women in the MVS. The MNV had a smaller vowel space compared to the MVS before and after the CAR. We observed a reduction in the vowel space in the MNV compared to the MNV after the VSL exercise.

Effects of different exercise on liver lipid accumulation and FGF21 secretion in obese rats

Objective: To investigate the effects of continuous exercise training (CT) and high-intensity interval exercise training (HIIT) on liver lipid metabolism and the correlation of the level of fibroblast growth factor 21(FGF21) in serum and liver tissues. Methods: Male SD rats were randomly divided into normal diet group (N) and obesity model group (H) after 1 week of adaptive feeding. Rats in the obesity model group were fed with 45% high-fat diet for about 8 weeks, and 20% weight increase compared with normal rats was considered as obesity. The rats were divided into normal diet control group (LC), normal diet HIIT group (LHI), normal diet CT group (LCT), High fat diet-induced obese control group (OC), obese HIIT group (OHI), and obese CT group (OCT) (n=10). Exercised rats were given weight-bearing swimming training intervention for 8 weeks. Blood samples were collected at least 24h after the last exercise intervention to detect the serum levels of inflammatory factors and FGF21. Liver tissue samples were collected to detect the lipid content, lipid metabolic enzyme content and FGF21 expression level. Results: Compared with LC group, the body weight, serum inflammatory factors levels and hepatic triglyceride content were increased significantly (P＜0.05). Hepatic triglyceride content was downregulated in LHI group and FGF21 expression level was enhanced in LCT group (P＜0.05). Compared with OC group, the body weight and hepatic triglyceride content were decreased significantly (P＜0.05), mitochondrial CPT-1β and β-HAD enzyme contents in liver were increased significantly (P＜0.05) in OHI group, the contents of LPL and FAT/CD36 enzyme in liver and the levels of FGF21 in serum and liver of OCT group were increased significantly (P＜0.05). Conclusion: Both exercise modes can reduce the body weight in normal and obese rats, and lipid deposition in the liver of obese rats. HIIT has a more significant effect on alleviating liver lipid deposition in obese rats by upregulating mitochondrial lipid oxidation level in normal and obese rats. CT improves the levels of FGF21 in serum and liver tissues of normal and obese rats, enhances enzyme contents that involved in fatty acids uptake to the liver, which has limited effect on alleviating lipid deposition in liver of obese rats.

Efekti programa vežbanja na razvoj agilnosti kod tenisera juniorske kategorije - sistematsko pregledno istraživanje

The aim of this research was to investigate the effects of different exercises on the development of tennis players' agility. The electronic database PubMed was used to search and collect relevant studies in the field of agility in tennis. This study was conducted based on the PRISMA statement. A total of 361 participants were included in this study. Twelve studies met the criteria in order to be included in this study. The results showed that the effect was statistically significant after each exercise program (high-intensity interval training, court tennis training, neuromuscular warm-up, sport-specific training, plyometric training, neuromuscular and performance training). The exercise programs lasted from 5 - 12 weeks with a weekly frequency of three times for 45 to 90 minutes. The results, obtained in this way, indicate a sensitive period for the development of agility in this age group, i.e. junior tennis players. The analyzed areas of agility assessment, frontal and lateral agility observed on the basis of agility assessment tests, were singled out.

The Effects of Different Exercise Programmes on Body Composition and Body Mass in Adults: A Review Article

The present systematic review will compile, analyse, and synthesize current results regarding the effects of various exercise programmes on body composition and body mass. Method: searching electronic databases such as PubMed, MEDLINE, Google Scholar, ScienceDirect, ERIC and compiling studies on the effects of various exercise programmes on reduction of body mass and changes to body composition. The range of the dates of publication is 1994–2020. The studies included healthy adult individuals and excluded values for body weight. Results: based on 16 analysed studies outlining the advantages of aerobic programmes for reductions in body mass and endurance resistance programmes for improvement in body composition parameters, a combined type of exercise is recommended as the best option. The recorded intensity of exercise ranged from 40–80% of maximum heart rate (MaxHR), with a weekly workout fre- quency of 3–5 times for 40–60 min, for six to 48 weeks. Moderate-intensity aerobic training of 60% MaxHR gave the best results for reducing body mass, while interval training with greater intensity of 80% MaxHR showed inconsistent results. Circuit resistance training indicated both positive and negative results for improvement in body composition parameters; exercise intensity varied from 50–70% MaxHR. Conclusion: various exercise programmes provide an effec- tive group type of work, leading to significant effects in reducing body mass and positive changes in body composition.

Effect of different exercises on effective factors involved in reverse cholesterol transfer in patients with coronary artery bypass surgery

Background: The present study aimed to compare the effect of different exercises on effective factors involved in reverse cholesterol transfer in patients with coronary artery bypass surgery (CABG). Materials and Methods: A number of 45 patients with CABGwere assigned to three groups: control (n=12), aerobic exercise (n=15), and resistance training (n=18). Three aerobic and resistance training sessions were performed per week for eight weeks. Anthropometric variables, expression of ABCG4 gen, as well as the serum levels of Apo-A and Apo-B, were measured before and after the training period. Data were analyzed using repeated measures of ANOVA. A p-value less than 0.05 was considered statistically significant. Results: Aerobic and resistance training significantly increased the expression of ABCG4 gene, compared to those in the control group (P=0.001); nonetheless, there was no significant difference between the two training groups (P= 0.021). Significant differences were observed in serum levels of Apo-A and Apo-B in both aerobic and resistance training groups, compared to those obtained in the control group (P=0.001). However, the difference between aerobic and resistance training groups was significant for Apo-A (P= 0.001), but not for Apo-B (P=1.000). Moreover, the ratio of Apo-A to Apo-B was significantly different for the resistance training group, compared to that in the control group (P= 0.001); nevertheless, it was not significant for the aerobic training group (P=1.000). Conclusion: As evidenced by the results of this study, resistance training improves cholesterol reverse transport regulators more than aerobic training; therefore, resistance training is recommended to regulate reverse cholesterol transfer.

Effect of Different Exercise Methods on Non-Alcoholic Fatty Liver Disease: A Meta-Analysis and Meta-Regression.

Exercise could alleviate non-alcoholic fatty liver disease (NAFLD), but it was not clear which exercise methods could effectively treat NAFLD. The purpose of this systematic review and meta-analysis was to evaluate the effects of different exercise patterns on eight indicators in patients with NAFLD. We searched PubMed, Scopus, Web of Science, China National Knowledge Infrastructure, and the Wanfang Data from its inception to 30 June 2020. This review includes all randomized controlled trials (RCT) that assessed and compared the effects of different exercise on eight indicator parameters in patients with NAFLD. The results indicate that aerobic exercises could significantly improve the eight indicators in patients with NAFLD including triglycerides (TG, weighted mean difference (WMD) = −0.53, 95%CI: −0.68~−0.39, Z = 7.37, p < 0.01), total cholesterol (TC, WMD = −0.39, 95%CI: −0.55~−0.23, Z = 4.76, p < 0.01), low density lipoprotein (LDL, WMD = −0.47, 95%CI: −0.68~−0.26, Z = 4.33, p < 0.01), high density lipoprotein (HDL, WMD = 0.12, 95%CI: 0.05~0.18, Z = 3.56, p < 0.01), alanine aminotransferase (ALT, WMD = −6.14, 95%CI: −10.99~−1.29, Z = 2.48, p < 0.05), aspartate aminotransferase (AST, WMD = −5.73, 95%CI: −9.08~−2.38, Z = 3.36, p < 0.01), and body mass index (BMI, WMD = −0.85, 95%CI: −1.19~−0.51, Z = 4.92, p < 0.01). Resistance exercises could significantly reduce the levels of TG (WMD = −0.56, 95%CI: −0.85~−0.28, Z = 3.86, p < 0.01) and AST (WMD = −2.58, 95%CI: −4.79~−0.36, Z = 2.28, p < 0.05) in the patients. High-intensity interval training could significantly improve the level of ALT (WMD = −6.20, 95%CI: −9.34~−3.06, Z = 3.87, p < 0.01) in patients with NAFLD. These three exercise methods had different effects on the eight indexes of NAFLD in our present meta-analysis, providing some reference for the establishment of exercise prescription for patients with NAFLD.

Meta-Analysis of the Effect of Exercise Intervention on Improving the Executive Function of College Students

Objective To systematically evaluate the effects of different exercise styles on executive function of college students through a meta-analysis of relevant literatures at home and abroad, and to provide evidence-based reference for future studies on mental health and teaching. Method to "aerobic exercise" and "movement" executive function, "cognitive" "college students/female college students" "aerobic exercise/exercise" seven "executive function" keywords retrieval at home and abroad, such as database, retrieval time for January 2021. Literature screening was conducted, and a total of 6 relevant studies were included with high literature quality scores. Meta-analysis was performed on the fixed model. Results The combined effect size of exercise intervention on inhibition function of college students [SMD=2.73, 95%CI: 0.99 ~ 3.48, P < 0.01]. The combined effect size of exercise intervention on refresh function of college students [SMD=-82.52, 95%CI:-127.89 ~ -37.15, P < 0.01]; the combined effect size of exercise intervention on the conversion function of college students [SMD=-98.48, 95%CI:-168.56 ~ -28.39, P < 0.01]. Conclusion Aerobic exercise and bicycle can effectively improve the executive function of college students, while resistance exercise has no improvement effect. the exercise intervention of 30-50min/time has the best effect on improving the inhibition function, conversion function and refresh function of college students. The short-term intervention of 1-2 weeks or the intervention of 8 weeks can improve the inhibition function, conversion function and refresh function of college students. there is no gender difference in the improvement effect of exercise intervention on executive function of college students.
