ABSTRACT
Background and objectives: Sirtuin-1 (SIRT1) is a conserved a NAD+-dependent protein deacetylase essential for cellular metabolism and defence against oxidative stress and endothelial dysfunction. This study aimed to compare effects of 8 weeks of aerobic and combined training on serum level of SIRT1 and PGC1-α in coronary artery bypass graft patients.
Methods: In this semi-experimental study, 45 non-active men (mean age 47.4 ± 3.3 years) who had undergone coronary artery bypass graft surgery were randomly divided into three groups: aerobic training, combined resistance and aerobic training and control. Trainings were performed at 80% of maximum heart rate, three sessions a week for 8 weeks. Blood samples were collected 24 hours before the first exercise session and 48 hours after the last training session. T-test and one-way analysis of variance were used for assessment of within-group and between-group differences, respectively. P-values less than 0.05 were considered as statistically significant.
Results: The 8-week aerobic and combined training increased serum levels of SIRT1 and PGC-1α compared with the control group, and significantly decreased the weight of subjects (p=0.001). There was no significant difference in serum levels of SIRT1 and PGC-1α between the two training groups (P≥0.05).
Conclusion: Both combined and aerobic training significantly improve the SIRT1 and PGC-1α levels in coronary artery bypass graft patients.
KEYWORDS: Combined training, Aerobic training, PGC-1α, SIRT1, CABG patient.
