Brief Summary
This study evaluates whether resistance exercise will improve immune responses to the seasonal influenza vaccine in older adults. One third of the participants will perform exercise in the arm that receives the vaccine, one third of the participants will perform the same exercise in the arm that does not receive the vaccine, and one third will only receive the vaccine.

Outcome Measures
Primary Outcomes (4)
Cell mediated immunity change at 6 weeks post-vaccine
The change in the peripheral blood mononuclear cell response to overnight ex vivo culture with the seasonal quadrivalent vaccine detected via Interferon-gamma ELISPOT will be calculated from baseline at 6 weeks post-vaccine
baseline and 6 weeks
Antibody titer change at 6 weeks post-vaccine
The change in influenza-specific antibody titers in serum measured by hemagglutination inhibition assay will be calculated from baseline at 6 weeks post-vaccine
baseline and 6 weeks
Cell mediated immunity change at 6 months post-vaccine
The change in the peripheral blood mononuclear cell response to overnight ex vivo culture with the seasonal quadrivalent vaccine detected via Interferon-gamma ELISPOT will be calculated from baseline at 6 months post-vaccine
baseline and 6 months
Antibody titer change at 6 months post-vaccine
The change in influenza-specific antibody titers in serum measured by hemagglutination inhibition assay will be calculated from baseline at 6 months post-vaccine
baseline and 6 months
Secondary Outcomes (2)
Muscle soreness
7 days
Influenza-like symptoms
Measured monthly for six months
Study Arms (3)
Exercise and vaccine in same arm
EXPERIMENTAL20 min eccentric resistance exercise of deltoid and biceps brachii in non-dominant arm, followed immediately by intramuscular injection of seasonal quadrivalent influenza vaccine in non-dominant arm
Exercise and vaccine in different arms
ACTIVE COMPARATOR20 min eccentric resistance exercise of deltoid and biceps brachii in dominant arm, followed immediately by intramuscular injection of seasonal quadrivalent influenza vaccine in non-dominant arm
vaccine only
NO INTERVENTION20 min rest followed immediately by intramuscular injection of seasonal quadrivalent influenza vaccine in non-dominant arm
Interventions
10 sets of 5 repetitions of 80% of calculated one-repetition maximum weight of lateral side arm raise and biceps curls, alternating
