These studies suggest that regular exercise can enhance immune responses and delay immunosenescence in aging individuals, although aging-related changes in neuroendocrine function and T cell-dependent functions can impact the immune response to exercise.

Aging is associated with a decline in immune function, a phenomenon known as immunosenescence. This decline contributes to increased susceptibility to infections, poorer vaccine responses, and higher incidences of malignancies in the elderly. Exercise has been studied for its potential to modulate immune responses and possibly mitigate some of the adverse effects of aging on the immune system.
Exercise and Enhanced Immune Function in the Elderly:
Neuroendocrine Changes and Immune Modulation:
Impact of Lifelong Exercise:
Resistance Exercise and Immune Response:
Gender and Age Differences in Immune Response to Exercise:
Aging leads to a decline in immune function, but regular exercise can mitigate some of these effects. Physical activity enhances various aspects of immune function in the elderly, including T-cell activity, NK-cell cytotoxicity, and cytokine production. Neuroendocrine changes with age also play a significant role in modulating immune responses to exercise. Lifelong exercise appears to preserve immune function better, and resistance exercise can help restore some age-related immune alterations. Gender and age differences further influence how the immune system responds to exercise, underscoring the complexity of the interaction between aging, exercise, and immune function.
