Aim: Precise therapeutic strategies and simultaneous investigation of the mechanisms involved in obesity are essential. Therefore, the present study aimed to investigate the effect of high-intensity interval training on soleus muscle FGF21 expression and lipid profile in rats fed a high-fat diet. Methods: For this purpose, 24 healthy adult male rats (Age: six weeks, weight: 200±20 grams) were randomly divided into four groups: control (CON) (N=6), control+exercise (CON+EXE) (N=6), high-fat diet (HFD) (N=6), and high-fat diet+exercise (HFD+EXE) (N=6). Diet and exercise interventions were initiated simultaneously and continued for 10 weeks. HIIT training consisted of eight periods of interval activity (90% MRC for 2.5 min) with active rest periods (50% MRC) for 2.5 min). The PCR_ method was used to examine FGF21 expression in the soleus muscle. Serum lipid indices were also measured. One-way ANOVA and Tukey's post hoc test were used to analyze the data. The significance level was considered to be P<0.05, and statistical analyses were evaluated using SPSS27 software. Results: By performing HIIT, weight and BMI were reduced, and LDL, cholesterol, HDL, and HDL/LDL ratio were increased in the training groups compared to those in the control group (P=0.001). The expression of FGF21 in the soleus muscle was significantly higher in the training group than in the control group (P=0.001). Conclusions: Ten weeks of HIIT without caloric restriction could potentially increase FGF21 expression and improve lipid profiles and weight loss. Therefore, this type of training can modulate and regulate obesity and its complications, without caloric restriction.
