Abstract:
This study assesses the effects of Qi-training on natural killer cell cytotoxicity. Nine experimental subjects did 1 h of Qi-training, and 9 control subjects relaxed during the same time. Natural killer cell cytotoxicity increased 60% immediately after Qi-training (p<.01) and returned to the basal level within 2 h after training. Natural killer cell subset number did not change after Qi-training. Natural killer cell cytotoxicity and cell number were not significantly correlated. These data suggest that Qi-training has an acute stimulatory effect on natural killer cell activity, but has no effect on phenotypical changes in the natural killer cell subset.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
