Does cardiovascular exercise training improve influenza vaccine seroprotection in sedentary older adults?
Regular endurance exercise improves influenza vaccine responses and reduces illness severity in sedentary older adults.
Participants randomized to cardiovascular exercise experienced improvements in influenza seroprotection throughout the entire influenza season, whereas those in the balance and flexibility intervention did not. Although there were no differences in reported respiratory tract infections, the exercise group exhibited reduced overall illness severity and sleep disturbance. These data support the hypothesis that regular endurance exercise improves influenza vaccine responses.
