Effect of exercise, aging and functional capacity on acute secretory immunoglobulin A response in elderly people over 75 years of age

Background:  Age‐associated decline in immune function and regulation, referred to as immunosenescence, brings about an increased incidence of infectious diseases in the aged; however, there are few data on the effect of aging and exercise on mucosal immune function in elderly people. Moreover, there is no evidence on whether the change in functional capacity affects mucosal immunity in elderly people. Therefore, the aim of the present study was to examine the effects of exercise, aging and functional capacity on mucosal immune function in elderly people over 75 years of age.
