Exercise >>> Immune Response

[Guest guest]

Hi folks:

" Exercise Increases Immunity in Older Men

Men 65 and older who exercise regularly can better battle antigenic

challenge than sedentary older men, and their immune response was

equal to that of active younger men, according to a study published

in the August 2004 Journal of Applied Physiology. Monika Fleshner,

MD, and colleagues at the University of Colorado studied the immune

system response of 46 physically active and sedentary younger (ages

20 to 35) and older (ages 60 to 79) men by twice injecting them with

a benign substance during a month to measure the immune response in

the blood. The sedentary men had not exercised regularly in the two

years prior to baseline; physically active men exercised at least

three times per week for two or more years. The blood tests showed

that older active seniors had significantly higher immune system

responses than sedentary seniors, and that the immune response

matched that of the younger men. "
