Lifestyle modification with regular exercise can improve metabolic diseases by reducing lipid profile and inflammation. Probiotics have been recently recommended not only for gastrointestinal diseases but also for metabolic and even degenerative diseases. Therefore, in the present study, the effect of high-intensity interval training (HIIT) and Lacticaseibacillus rhamnosus strain GG (LGG) as a probiotic on tetracycline-induced hepatic steatosis in an animal model was evaluated. Eighty male Wistar rats were randomly divided into eight groups (n = 10 in each group): control, LGG, HIIT, LGG + HIIT, tetracycline-induced (TTC), TTC + LGG, TTC + HIIT, and TTC + LGG + HIIT. The rats are treated by intraperitoneal injection (IP) with 140 mg kg−1 tetracycline, an antibiotic previously known to induce steatosis. The exercise training groups performed HIIT 5 days/week for 5 weeks, and 107 CFU/ml of Lacticaseibacillus rhamnosus GG was gavaged for the LGG groups 5 days/week for 5 weeks. Fatty droplets in the hepatocyte were considered with Oil Red staining. TTC-receiving rats have more lipid accumulation and larger lipid droplets in the liver compared to healthy animals. The two-way ANOVA showed that the interaction of LGG and HIIT significantly decreased LDL, cholesterol, and triglyceride in the healthy rats (p < 0.05). In TTC-receiving rats, the interaction of LGG and HIIT significantly increased HDL and SOD and significantly decreased triglyceride, ALP, AST, and ALT (p < 0.05). The consumption of probiotic LGG, along with HIIT with control of lipid profile and liver enzymes and improvement of the oxidative capacity, neutralizes the damage of TTC to liver tissue. Therefore, this protocol can be recommended for people with hepatic steatosis. [ABSTRACT FROM AUTHOR] |
