Background and Aim: Considering the roles of resistin, leptin and adiponectin in metabolic activities, especially in relationship with exercise and adipose tissue, and the lack of research in a related context this study was carried out to examine the effect of aerobic training and high-fat diet on leptin, adiponectin and resting serum levels of resistin in male rats.
Methods: This research was conducted using an experimental method. For this purpose, 28 male rats with an average weight of 152 ± 5g and the age of four weeks were divided into four groups: normal diet (N = 7), high-fat diet (N = 7), training (N = 7) and high-fat diet+ training (N = 7) groups. High-fat diet groups underwent high-fat diet (HF: 5/817 kcal/g) for 30 days. From the 60th day of life, a normal fat diet (NF: 3/801 Kcal/g) was applied Aerobic exercise wascarries out on a treadmill, for four weeks, three times a week (12 weeks from 60th to 98th days of life), 40 minutes with 50 cm/s speed. ELISA method was used to measure the biochemical markers including resistin, adiponectin and leptin. Factorial analysis of variance was used for statistical analysis. If post hoc comparisons were needed to compare groups two by two, Turkey’s post hoc test was used according to the results of Levine’s test.
Results: The resultes showed that high fat diets cause a significant increase (p = 0/001) in serum levels of leptin (12/77 ± 1/12), leptin to adiponectin ratio (0/62 ± 0/13) and resistin (4/22 ± 0/58), and a decrease in (p = 0/01) adiponectin (21/12 ± 4/28) in male rats. However, aerobic exercise was accompanied by a significantdecrease(p = 0/003) in serum levels of leptin (6/17 ± 0/96), leptin to adiponectin ratio (0/14 ± 0/03), and resistin (2/42 ± 0/69). Moreover, an increase in (p = 0/001) adiponectin serum levels (42/74 ± 4/9) was observed.
Conclusion: Aerobic exercise might have beneficial effects on adiponectin, leptin, and leptin toadiponectin ratio in people with high-fat diet. On the other hand, high-fat diet is associated with detrimental effects on these cytokines and resistin.
