| Research Abstract |
In this study, we found that when the muscle metaboreflex activation by forearm muscle ischemia after the handgrip exercise caused increase in sympathetic nerve activity and secretion of catecholamine without large rise in circulatory blood flow, the circulating count of NK cells as well as NK cell cytotoxicity increased. In addition, when passive bicycle exercise induced increase in circulatory blood flow and the fall of catecholamine concentration, we found that the circulating count of helper T cells, killer T cells and B cells increased. These findings advance elucidation of regulatory mechanisms of immune-cells dynamic state in circulatory blood during exercise, and will be a significant academic base in considering the efficacy of the exercise training in promotion of health.
