The objective of the present study was to investigate the effects of combined resistance and endurance exercise training on serum levels of the biomarkers MuRF-1 and Atrogin-1, as well as other diabetes-related biomarkers, in middle-aged women diagnosed with type 2 diabetes.
This quasi-experimental study involved thirty women diagnosed with type 2 diabetes. After a thorough review of medical records and assessment of inclusion criteria, participants were randomly assigned to either a combined training group (CT) or a control group (CO). The exercise group underwent a structured training protocol three times a week for a duration of eight weeks. Blood samples were collected pre- and post-intervention by a qualified laboratory specialist and were analyzed using human ELISA kits. Data analysis was conducted utilizing the Shapiro-Wilk test, Levene’s test, and independent and paired samples t-tests via SPSS software version 26.
The findings revealed significant weight increases (P< 0.001), Body Mass Index (BMI) (P< 0.001), waist-to-hip ratio (WHR) (P< 0.001), and skeletal muscle mass (SMM) (P< 0.001) following the implementation of the combined exercise program. Additionally, fasting insulin levels (P< 0.001), fasting blood glucose levels (P< 0.001), and HbA1c levels (P< 0.001) significantly decreased in the exercise group in comparison to the control group. However, no significant difference was observed in the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) index (P= 0.758) between the groups. Notably, serum levels of the muscle atrophy markers MuRF-1 (P< 0.001) and Atrogin-1 (P< 0.001) exhibited significant reductions following eight weeks of combined exercise training.
This study represents one of the few investigations to concurrently examine alterations in serum levels of both MuRF-1 and Atrogin-1 following combined exercise training. The results indicate that combined exercise training may effectively reduce muscle atrophy in individuals with type 2 diabetes by lowering serum levels of MuRF-1 and Atrogin-1. Furthermore, engaging in combined physical activity may yield overall health benefits for individuals affected by type 2 diabetes.
