Abstract
The aim of this study is to investigate the impact of exercise on intermediate disease markers in populations with overweight and obesity, providing evidence-based recommendations for clinicians to utilize these markers in developing exercise prescriptions for this group. The study was conducted by retrieving data from PubMed, Embase, Cochrane Library, Web of Science, and CNKI and only including Randomized Controlled Trials (RCTs) to examine the effect of different exercise interventions on intermediate disease markers in overweight and obese people. The quality of the included studies was evaluated using the Cochrane Bias Risk Assessment tool and the data was analyzed using Stata 15.1 data analysis software. The RCTs were collected from January 2017 to March 2024. A total of 56 RCTs were included and the results of 10 outcomes were analyzed using random effects meta-analysis. The total sample size used in the study was 3193 The results showed that resistance training significantly reduced total cholesterol (SUCRA: 99.9%), triglycerides (SUCRA: 100.0%), low-density lipoprotein (SUCRA: 100.0%), systolic pressure (SUCRA: 92.5%), and increased high-density lipoprotein (SUCRA: 100.0%). Aerobic exercise significantly reduced insulin (SUCRA: 89.1%) and HbA1c (SUCRA: 95.3%). Concurrent training significantly reduced HOMA-IR (SUCRA: 93.8%), diastolic blood pressure (SUCRA: 71.2%) and Glucose (SUCRA: 87.6%). Exercise has a significant impact on intermediate disease markers in populations with overweight and obese. Compared with no exercise, exercise lowers total cholesterol, triglycerides, LDL, systolic blood pressure, diastolic blood pressure, HOMA-IR, insulin, and HbA1c, and increases HDL in people with overweight and obese. These findings provide evidence-based recommendations for exercise interventions aimed at weight reduction and the prevention of chronic diseases in individuals with overweight and obese.

Introduction
The issue of overweight and obesity, characterized by an excessive accumulation of body fat, has emerged as a global health concern in accordance with the World Health Organization (WHO)1. Between 1975 and 2016, the worldwide prevalence of obesity tripled, resulting in a scenario where obese individuals outnumber those who are underweight, except for regions such as sub-Saharan Africa and Asia. Obesity is linked to multiple chronic diseases including type 2 diabetes, metabolic syndrome, cardiovascular disease, and certain cancers; this underscores its significant impact on health2,3,4,5,6.
Enhanced prevention and management strategies for obesity and its associated chronic diseases have been identified, with exercise playing a pivotal role. Recognizing this significance, the World Health Organization (WHO) has introduced the "Global Action Plan on Physical Activity 2018–2030" to promote physical activity worldwide. Regular exercise not only aids in reducing body fat through increased energy expenditure but also confers benefits such as improved blood lipid profiles, delayed onset of type 2 diabetes, reduced blood pressure, and enhanced mental health7,8,9,10. Importantly, physical activity is devoid of adverse effects; however, it is advisable to seek professional medical advice before initiating a new exercise regimen, particularly for individuals with pre-existing health conditions11,12,13.
However, the challenge lies in the dearth of evidence-based guidelines for selecting an efficacious exercise regimen that effectively targets specific intermediate disease markers in overweight and obese individuals. The appropriate exercise program has the potential to ameliorate these markers, facilitate weight loss, and mitigate the duration and adverse effects associated with conventional pharmacotherapies, thereby contributing to chronic disease prevention.
This paper employs network meta-analysis, a contemporary evidence-based methodology that assesses the relative efficacy of different treatments14, to comprehensively evaluate the impact of multiple exercise interventions on disease markers in overweight and obese individuals. By integrating both direct and indirect evidence from various studies, this study examines the effects of aerobic, resistance, and concurrent training on metabolic markers. The findings provide a solid foundation for developing effective exercise programs for weight management and disease prevention, aiming to inform healthcare professionals, researchers, and policymakers about promoting physical activity..
Materials and methods
Search strategy
The researchers in this paper searched five electronic databases (PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science and CNKI) from January 2017 to March 2024. The search strategy was constructed around the PICOS tool: (P) Population: people with overweight and obese; (I) Intervention: exercise; (C) Comparator: Carry out normal daily activities without calorie restriction according to habitual lifestyle, and do not participate in any physical activities during the experiment; (O) Outcomes: intermediate disease markers in overweight and obese people; (S) Study type: RCTs. The detailed search strategy is shown in Table 1 (PubMed is used as an example).
Inclusion criteria
(1) Participants were only overweight (BMI ≥ 25 kg/m2) or obese (BMI ≥ 30 kg/m2) and had no other medical conditions; (2) The experimental group administered exercise interventions only to overweight and obese people; (3) Ability to determine the isolated effect of movement; (4) People in the control group did not participate in any intervention and only performed normal daily activities; (5) Clinical randomized controlled trial; (6) Outcome indicators including at least one of the following: Total Cholesterol, Triglycerides, High-density lipoprotein, Low-density lipoprotein, Systolic Blood Pressure, Diastolic Blood Pressure, Homeostatic Model Assessment of Insulin Resistance, Glucose, Insulin, Hemoglobin A1c.
Exclusion criteria
(1) Studies with incomplete or unreported data (2) Studies from non-randomized controlled trials [including quasi-randomized controlled trials, protocols, conference abstracts, case reports or correspondence] (3) Research on animal experiments.
Study selection
The screening and exclusion of literature was conducted using the EndNote literature management software. The process began with two researchers reviewing the titles of the literature to eliminate duplicates and any non-randomized controlled trial studies, review papers, conference papers, protocols, and correspondence. Next, both researchers read the abstracts of the remaining literature to determine which studies to include and which to exclude. Finally, the full text of the remaining studies was read by both researchers to confirm their inclusion. If there were any discrepancies in the final selection of studies, the two researchers discussed and resolved the issue with the assistance of a third researcher.
Data extraction
A seven-item, standardized and pre-selected data extraction form was used to record data for inclusion in the study under the following headings: (1) author, (2) year of publication, (3) country, (4) study period, (5) sample size, (6) mean age, and (7) details of the exercise intervention.
Risk of bias evaluation of the included RCTs
According to the Cochrane Intervention Systematic Review Manual, two review authors assessed the risk of literature bias using the widely recognized Cochrane tool, considered the gold standard for assessing risk of bias in randomized controlled trials (RCTs).The assessment was based on six key components: selection bias, including the proper generation of random sequences and allocation concealment; performance bias, including participant and personnel blinding; detection bias, including outcome assessment blinding; attrition bias, which addresses incomplete outcome data; reporting bias, which examines selective reporting; and other bias, such as crossover carryover effects in RCTs15. The results of this assessment were clearly and concisely presented visually. We also used the STATA software to generate funnels to assess potential publication bias in small studies based on symmetry criteria.
Data analysis
In this study, we conducted a meta-analysis to investigate the effects of various exercise interventions on disease markers among overweight and obese people. To maintain consistency in the studies, all interventions were quantified as continuous variables. We used a random-effects model to accommodate any differences between studies. Subsequent analysis was carried out using the STATA 15.1 software. Here, we used standardized mean differences (SMDs) to measure different effect sizes between different interventions. In addition, 95% confidence intervals were used to estimate the possible range of these differences.
We plan to employ the nodal method as a means of quantifying and demonstrating the concordance between indirect and direct comparisons.
These calculations will be conducted using the Stata software. If the P-value is greater than 0.05, it would indicate a successful consistency test16. To visualize the relationships between different motor interventions, a network diagram was utilized. This diagram, generated using Stata software, depicted each mode of intervention as a node, with the connecting lines between nodes representing direct comparisons. The size of each node reflected the volume of literature related to the corresponding exercise intervention, and the thickness of connecting lines represented the number of studies comparing the interventions17.
The Cumulative Ranking Curve (SUCRA) method was used to rank the relative effectiveness of each intervention. This method converts the therapeutic effect of each intervention into an area chart, where the values of the area and area under the curve represent the likelihood of the optimal intervention. In this study, the larger the area under the curve and the closer the value was to 100%, the better the effect of the intervention. In this study, the larger the area under the curve, the closer the value was to 100%, the better the effect of the intervention.
Results
Study and identification and selection
A total of 7218 documents were retrieved from the electronic database, and an additional 22 documents were manually searched. After eliminating duplicates, the remaining 5623 documents were read for titles and abstracts, and 5281 articles were excluded due to irrelevance after reviewing their titles and abstracts. The remaining 342 documents were read in full and 286 documents were again excluded (for reasons including: non-randomized controlled trials, incomplete data, conference papers and failure to meet the interventions included in this review), leaving a final remaining 56 documents to be included in this study (Fig. 1).

Discussion
In this study, we investigated the effects of various exercise interventions on the levels of abnormal intermediate disease biomarkers in populations with overweight and obese. A total of 56 studies, including 14 different exercise programs and 3193 people with obese and overweight, were included in the analysis, resulting in a substantial sample size. Our research findings suggest that resistance training can significantly improve dyslipidemia, reduce systolic blood pressure, while concurrent training can significantly reduce diastolic blood pressure and blood glucose levels. Aerobic exercise can significantly reduce blood glucose levels in obese and overweight individuals. Aerobic exercise is considered the most effective exercise intervention for reducing glycated hemoglobin and insulin levels, resistance training is the most effective exercise intervention for lowering systolic blood pressure and blood lipids, and concurrent training is the most effective exercise intervention for regulating diastolic blood pressure, reducing blood glucose and insulin resistance.
Numerous previous studies have shown that intermediate disease biomarker levels are abnormal in populations with overweight and obese56,57,58,59. The intermediate disease biomarkers discussed in this article reflect people' blood lipid, blood glucose, blood pressure levels. These markers are closely related to the metabolic and cardiovascular status of people, as well as the development of chronic diseases. Therefore, by analyzing these intermediate disease biomarkers, healthcare providers can improve people' overall health status and reduce the risk of chronic diseases based on the exercise intervention recommendations provided herein.
Aerobic exercise
Aerobic exercise is widely regarded as the most effective method for weight loss in obese individuals ,this form of exercise, which involves continuous physical activity leading to increased heart rate and respiration, not only enhances strength and endurance but also stimulates metabolism, reduces fat storage, and promotes cardiovascular health, thereby contributing to overall well-being60,61.
The outcomes of our network meta-analysis revealed that compared to no exercise, aerobic exercise significantly managed blood lipid levels, blood pressure, and blood glucose in overweight and obese individuals. Moreover, among various exercise modalities, aerobic exercise stood out as the most effective method in lowering insulin and glycated hemoglobin concentrations within this population.
Clinicians can tailor aerobic exercise prescriptions to people with overweight and obese based on the results of this study18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34, and can choose appropriate forms of exercise from dance, walking, endurance training, cycling, running, and MICT. It is recommended that the duration of each exercise range from 30 to 90 mins, with a frequency of three to six times a week. Exercise intensity should be tailored to the patient's specific needs in order to effectively lower their blood glucose levels. Regular aerobic exercise can improve metabolic and physiological functions, alleviate physical strain, and boost overall health status.
Resistance training
Our research findings reveal that all exercise types can effectively lower people' abnormal blood lipid levels when compared to sedentary control groups. Nevertheless, resistance training stands out as the most successful exercise type within this study. Resistance training not only has the ability to regulate blood lipid levels but can also decrease people' systolic blood pressure. It is crucial to highlight that, when compared to the non-exercising experimental control group, resistance training demonstrates less efficacy in reducing blood glucose levels for individuals with obese and overweight.
Based on our literature review35,36,37,38,39,40,41,42,43, clinicians may consider prescribing traditional exercises such as squats, lunges, bicep curls, push-ups, and shoulder presses. Each exercise should be executed with 8–15 repetitions per set and 2–6 sets per training session. In addition, alternative and engaging resistance training techniques, like rope training and whole-body vibration training, can be taken into account to boost people' enthusiasm, interest, and overall exercise performance.
Exercise sessions should span between 20 and 60 min, with warm-up and stretching exercises recommended before and after each session. A frequency of three or four times per week is advised, and exercise intensity should be tailored to suit the individual's unique needs.
Concurrent training
Concurrent training (CT) is a comprehensive exercise method that combines aerobic and resistance training. Compared to inactivity, CT demonstrates significant effectiveness in adjusting blood glucose, HOMA-IR, and diastolic blood pressure in overweight and obese individuals. However, it has a limited impact on glycated hemoglobin levels. Therefore, it is not recommended to choose CT as the exercise approach when glycated hemoglobin, an intermediate disease marker, is abnormal in individuals with overweight and obese.
Therefore, we recommend that clinicians use CT as the main mode of exercise in their prescriptions for people with overweight and obese with significant abnormalities in diastolic blood pressure, blood glucose, and insulin resistance markers.
Clinicians can incorporate interval training, karate, HICT, or HIEX as exercise forms in their prescriptions, scheduling three to five training sessions per week, each lasting between 11 and 60 mins23,29,34,44,45,46,47,48,49,50,51,52,53. The specific exercise intensity should be customized based on each individual's particular needs.
In summary, our study bears clinical significance in two key respects: firstly, it provides a theoretical foundation for the fact that exercise can significantly mitigate abnormal intermediate disease markers in people with overweight and obese; secondly, it allows clinicians to integrate our findings with people' abnormal intermediate disease markers to tailor exercise prescriptions, thereby fostering overall patient health.
Strengths and limitations
Our study encompasses 56 research projects and 3193 people, which constitutes a substantial sample size, and offers a comprehensive and updated review of exercise interventions in people with overweight and obese. We've integrated three innovative interventions—water sports, whole—body vibration training, and rope training—to compare with other interventions, thereby delivering the most recent and exhaustive evidence-based recommendations.
However, our study shares some limitations with the research it is based on. Despite our efforts to control study heterogeneity, some heterogeneity is inevitable between studies, such as the proportion of male and female participants and regional variations. Readers should interpret our findings cautiously due to the strict literature screening criteria, the limited number of included studies, and limited direct comparison evidence for certain interventions. This highlights the need for further expansion of relevant research.
Lastly, our study only included 14 exercise interventions that met the literature screening criteria, but in reality, there are many more interventions that can positively impact the intermediate markers of individuals with overweight and obese. Future research can broaden the scope by including more types of exercise interventions, offering more choices for different people; analyze the response differences among different populations (such as age, gender, race, and cultural background) to exercise interventions, to develop more personalized exercise plans; and explore the long-term effects of exercise interventions to better assess their sustainability in improving the health of overweight and obese people.
In summary, although our study has some limitations, it still provides valuable information on exercise interventions for overweight and obese people. By analyzing various types of exercise interventions, we offer evidence-based recommendations for healthcare providers on how to develop more effective treatment strategies. In the future, we hope to see more research on exercise interventions to better meet the needs of different people and help them achieve healthier lifestyles.
Conclusions
The study hints at potential mechanisms by which resistance, aerobic, and concurrent training could influence improvements in health markers for individuals with overweight and obesity, thus shedding light on the varying impacts of different exercise modalities on health outcomes. Resistance training enhances lean muscle mass, leading to an increase in metabolic rate and fat oxidation, improvement in lipid profiles , and reduction in systolic blood pressure. Conversely, aerobic training primarily improves insulin sensitivity and cardiovascular health while lowering blood glucose levels but may not significantly enhance muscle strength. Concurrent training combines the advantages of both exercise types by addressing diastolic blood pressure and blood glucose levels despite potential interference effects that could impact optimal strength or endurance gains.
Each modality offers distinct advantages: resistance training is optimal for enhancing muscle strength and lipid profiles, aerobic training excels in providing cardiovascular benefits and managing glucose levels, while concurrent training provides a comprehensive approach to simultaneously address multiple health markers. However, the selection of exercise should be tailored to individual health objectives, preferences, and specific conditions while acknowledging the limitations and strengths associated with each modality (Supplementary Information).
Based on the collective insights derived from this study, it is recommended that clinicians adopt a personalized exercise prescription approach when working with overweight and obese populations. By aligning exercise modalities with individual health profiles and objectives, clinicians can develop targeted interventions that not only enhance overall health but also mitigate the risk of chronic conditions. This approach capitalizes on the distinct advantages offered by resistance, aerobic, and concurrent training to cater to diverse health needs.
