Abstract

Background and purpose: Excessive fat deposition is associated with cardiovascular diseases, diabetes as well as hypertension. The aim of this study was to determine the net effect size of high intensity interval training (HIIT) on some factors associated with insulin sensitivity in adults with overweight and obesity.
Materials and methods:  A search for English articles was conducted in Web of Science, Scopus, and PubMed databases without limiting the year of publication until February 2023. To calculate the effect size, WMD and 95% confidence interval were calculated using random effect model. Fixed effect model meta regression was used to determine treatment effects associations with other variables.
Results: In total, 13 studies with 446 adults with overweight and obesity (149 females, and 317 males) with 24.7-57 years old were included in the present meta-analysis. The results showed that HIIT caused a significant decrease in fasting glucose [WMD=-8.65 mg/dL, P=0.002], fasting insulin [WMD=-1.88 U/L P=0.005], and diastolic blood pressure (DBP) [WMD=-3.33 mmHg. Weak correlations were observed in between HIIT’s net effect on DBP and insulin (r=-0.32, p=0.019) as well as with subjects’ age (r=-0.29, p=0.037) respectively in meta-regression assessments.
Conclusion: The rate of DBP reduction is sharper and these changes are also correlated with age. Therefore, HIIT is suggested as a Non-pharmacological Approach to prevent against future cardiometabolic risk factors in this population.

Abstract

The purpose of this study was to investigate the impact of combining aerobic exercise (AE) and vegetarian diet (VD) on blood pressure and body weight in adults with overweight and obesity. The PubMed, Web of Science, Scopus, and Google scholar databases were searched until February 2023 for English articles, and 1065 articles were found. Meta-analyses were performed to compare the impact of aerobic exercise and vegetarian diet on body weight, blood pressure in adults with overweight and obesity. Data analysis was performed using random effect model and weighted mean differences (WMD). The results of meta-analysis of 25 studies with 10192 adults showed that combined aerobic exercise and vegetarian diet significantly decreased in body weight [WMD=-4.63, p=0.001] , systolic blood pressure [WMD=-6.94, p=0.001] , and diastolic blood pressure [WMD=-4.5, p=0.001] , in adults with overweight and obesity.  Aerobic training alongside vegetarian diet as a non-medication approach for weight loss and blood pressure control in adults with overweight and/or obesity. In addition, aerobic exercise and vegetarian diet with both types of duration (less than 12 weeks and more than 12 weeks) cause a significant decrease in blood pressure in adults with overweight and obesity.
