Woods: There have been some more recent studies aimed at determining the role of resistance training and high-intensity interval training on various immune parameters. My take of the literature is that there are still very few studies on this to make firm conclusions. We published a study in 20077 examining the influence of 5 months of Tai Ji Quan/Qigong could influence the immune response to influenza vaccination in older adults. We found significant increases in the magnitude and duration of antibody responses in Tai Ji Quan/Qigong participants when compared to controls. While I am unaware if these data have been replicated, a recent systematic review on the effects of yoga concluded that yoga might be beneficial for those suffering from diseases with an inflammatory component.8
