Abstract
BACKGROUND AND AIMS
Exercise activity is an important method for managing type 2 diabetes. This investigation examined the HIIT and continuous training on apelin, APJ receptor, NO, and cardiotrophin-1 in the cardiac tissue of diabetic rats.
METHODS
The animals were categorized into 3 groups of HIIT, continuous (CO), and control (C) (all animals were sacrificed immediately and 2 days after exercise training period). Rats underwent the treadmill exercise program either HIIT (12 bouts at 90-95% of VO2 max with 60 s rest at 50% of VO2 max) or CO (60-65% VO2 max for 40 min). Protocols performed 5 days per week for 8 weeks. Apelin, APJ receptor, NO, and cardiotrophin-1 protein expressions were measured using the Western blotting method in the left ventricle.
RESULTS
Immediately after HIIT and CO exercise protocols, apelin and CT-1 protein showed a significant difference in contrast by the C-0 group (p < 0.01). However, NO values were substantially higher in HIIT-0 compared to C-0 and CO-0 groups rats (p < 0.01). After two days of exercise protocols, apelin and NO protein showed a significant increase in HIIT and CO groups in contrast to the C animals (p < 0.01). Moreover, APJ and CT-1 protein significantly upregulated in CO-2 and HIIT-2 compared to the other groups (p < 0.01).
CONCLUSIONS
This study indicates that exercise training, despite the type, is an efficient method to modify apelin, APJ receptor, NO, and cardiotrophin-1 values in animals with type 2 diabetes.
