Background and Purpose: The aging process is associated with a state of chronic low-grade systemic inflammation, characterized by elevated serum levels of inflammatory markers such as interleukin-17 (IL-17) and interferon-gamma (IFN-γ). IFN-γ, a pro-inflammatory cytokine primarily produced by Th1 and CD4+ T cells, natural killer (NK) cells, and CD8+ T cells, serves as the primary activator of macrophages and plays a crucial role in both innate and adaptive cell-mediated immunity against intracellular pathogens. Considering the role of chronic inflammation in the development of age-related diseases and the importance of regulating inflammatory mediators, such as IFN-γ and IL-17, to improve the health of older adults, this study investigated the effects of a 12-week multicomponent exercise program, including aerobic, resistance, balance, and flexibility training, on serum levels of these cytokines in older men.
Materials and Methods: In this quasi-experimental study thirty-six volunteers (age, 66.88±3.96 years) were randomly assigned to either the multi-component exercise group (n=18) or the control group (n=18). The exercise program, was designed based on the ACSM guidelines for older adults, for 12 weeks, three sessions per week, incorporating a gradual progression in intensity tailored to participants’ capacities. Each exercise session included a 10-minute warm-up, the main exercise component (resistance, aerobic, and balance exercises), and a five-minute cool-down. Five milliliters of blood were drawn from the antecubital vein after a 12-hour overnight fast, and IFN-γ and IL-17 levels were measured using the ELISA laboratory method. Statistical analysis was performed using two-way repeated measures of ANOVA with SPSS software.
Results: The multi-component exercise program resulted in a significant decrease in serum levels of both Interferon-Gamma (p<0.001) and Interleukin-17 (p=0.001). Specifically, in the exercise group, IFN-γ and IL-17 levels decreased by 23.2% and 53%, respectively. No significant changes in the levels of these cytokines were observed in the control group during the study period.
Conclusion: The findings of this research clearly demonstrated that a 12-week multi-component exercise program, encompassing resistance, aerobic, and balance training, can effectively reduce key inflammatory markers such as interferon-gamma and interleukin-17 in older men. Therefore, these types of exercises can serve as a safe, effective, and non-pharmacological strategy for modulating immune responses, controlling chronic inflammation, and ultimately promoting overall health in the older adult population.
