The effect of eight weeks of aerobic training with stevia herbal supplement on heart tissue structure in obese rats
Understanding how aerobic exercise with herbal supplements can cause structural changes in the heart could lead to the development of new treatments to improve heart health. The aim of this study was to evaluate the effect of eight weeks of aerobic training with stevia herbal supplement on heart tissue structure in obese rats.
To implementation of this experimental research, 25 male wistar rats (5 healthy adult rats and 20 adults’ obese male rats) were divided into five groups: control (healthy), obese, obese-garlic, obese-aerobic training and obese-garlic. Aerobic training was performed. Aerobic exercise was performed on treadmill, 5 days week for eight weeks. The dose of stevia was 250 mg per kilogram of body weight in gavage. After anesthesia, an autopsy was performed and heart tissue was removed. Cardiac tissue sections were studied by hematoxylin-eosin (H&E) staining. The changes of heart tissue, Muscle cells, necrosis, inflammation and hyperemia were assessed, the severity and degree of these changes were performed based on microscopic and photomicrographs observations.
The results showed that in obese rat’s pathological changes of heart muscle and heart cells were observed in comparison with the control group. Aerobic training, consumption of stevia herbal supplement and aerobic training with consumption of stevia herbal supplement were associated with improvement of tissue and cellular changes in heart tissue.
the present intervention can probably have benefits for the structure of heart tissue during obesity.
