Abstract: (150 Views)
Background: The aim of the present study was to investigate the effect of high-intensity interval training on lipid profile, fasting blood glucose, body composition, and Vo2max in patients with type 2 diabetes or obesity.
Methods: The type of research conducted is a systematic meta-analysis review. A systematic search of published articles was conducted from PubMed, Web of Science, Scopus, Sid, and Magiran databases up to January 2024. The mean difference and 95% confidence interval (CI) were calculated using a random-effects model. Heterogeneity was assessed using the (I2) test and publication bias was assessed using visual analysis of funnel plots and Egger's test.
Results: The results showed that high-intensity interval training significantly reduced body fat percentage [standard mean difference (SMD)=-0.796, P=0/001], BMI (SMD=-0.378, P=0/001), WHR (SMD=-0.424, P=0/001), LDL (SMD=-0.694, P=0/001), TC (SMD=-0.495, P=0/001), TG (SMD=-0.317, P=0/001) and fasting blood glucose (SMD=-0.557, P=0/001) in patients group compared to the control group had a significantly higher VO2max. However, high-intensity interval training significantly increased Vo2max (WMD=-0.997, P=0/001), and HDL (WMD=-0.558, P=0/001) in patients group compared to the control group.
Conclusion: Based on the results obtained, high-intensity interval training can have a positive effect on metabolic indices, body composition, and aerobic capacity in patients with type 2 diabetes or obesity and improve the condition of these individuals. Therefore, it is suggested that in medical centers for diabetic and obese patients, under the supervision of sports and medical specialists, the beneficial effects of high-intensity interval training should be utilized and used as an auxiliary strategy for the treatment and improvement of these individuals.
