Introduction: This study aimed to investigate the effects of resistance, endurance, and combined training on IL-6 gene expression in the soleus muscle of male Wistar rats.
Methods: In this experimental study, forty-two-month-old male Wistar rats were randomly allocated to four groups (n = 10 per group): control, resistance training, endurance training, and combined training. The individual exercise protocols were implemented for eight weeks. Gene expression levels of IL-6 mRNA were quantified using real-time polymerase chain reaction (RT-PCR). All statistical analyses were conducted using SPSS software.
Results: After eight weeks, rats in the control group displayed a body weight increase exceeding 60%, which was significantly higher than that observed in the experimental groups (less than 50%). Regarding IL-6 gene expression, all experimental groups exhibited a significant reduction compared with the control group (P=0.001). Likewise, the differences in the magnitude of reduction between resistance training and combined training, as well as between endurance training and combined training, were statistically significant (P<0.05). Nevertheless, no significant difference was observed between the resistance and endurance training groups (P=0.001).
Conclusion: The results suggest that resistance, endurance, and combined training protocols may attenuate age-related weight gain in rats. Remarkably, combined training seems to be a particularly effective strategy for mitigating age-associated weight gain and potentially reducing oxidative stress. Future studies are warranted to extend these results and explore their applicability to human populations.
