Introduction and Purpose: The growing trend of obesity is directly linked to the development of various diseases, including type 2 diabetes. Physical activity plays a significant role in weight control and the prevention of metabolic diseases. This study aimed to investigate the effect of eight weeks of TRX training on insulin sensitivity indices, quality of life, general health, and body composition in overweight or obese men.
Materials and Methods: In this semi-experimental study, 30 overweight or obese male subjects aged 20 to 30 years were selected and randomly assigned to either the training group (n=15) or the control group (n=15). The TRX training protocol consisted of 8 weeks of training, three days a week for 40-45 minutes. Blood samples were collected at two stages, pre-test and post-test, to evaluate blood variables. Statistical analysis was performed using paired t-tests and analysis of covariance at a significance level of P ≤ 0.05, utilizing SPSS statistical software version 23.
Results: Following the TRX training intervention, the mean levels of HOMA-IR, McAuley's index, quality of life, general health, weight, BMI, and WHR in the training group significantly decreased compared to the control group (P ≤ 0.05). However, the difference in means between the two groups for the QUICKI index was not significant (P = 0.170).
Discussion and Conclusion: Based on the findings, TRX exercises can be recommended as a non-pharmacological solution for reducing risk factors, such as insulin resistance and increasing insulin sensitivity, while also improving quality of life and general health in overweight and obese individuals.
