研究概览
简要总结
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.
详细描述
Resistance exercise, particularly novel eccentric exercise, recruits immune cells to the targeted muscle. The exercises selected here targets the deltoid and biceps brachii muscles-those same muscles that the flu vaccine is delivered to during typical vaccination.

结局指标
主要结局
Cell mediated immunity change at 6 weeks post-vaccine
时间窗: baseline and 6 weeks
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
Antibody titer change at 6 weeks post-vaccine
时间窗: baseline and 6 weeks
The change in influenza-specific antibody titers in serum measured by hemagglutination inhibition assay will be calculated from baseline at 6 weeks post-vaccine
Antibody titer change at 6 months post-vaccine
时间窗: baseline and 6 months
The change in influenza-specific antibody titers in serum measured by hemagglutination inhibition assay will be calculated from baseline at 6 months post-vaccine
Cell mediated immunity change at 6 months post-vaccine
时间窗: baseline and 6 months
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
次要结局
- Influenza-like symptoms(Measured monthly for six months)
- Muscle soreness(7 days)
