Can A Dynamic Warm-Up Reduce The Magnitude Of Immune Perturbation Following Vigorous Aerobic Exercise, Mahmoud T. Elzayat, Emily C. Lavoy

International Journal of Exercise Science: Conference Proceedings

Exercise transiently increases several leukocyte populations in peripheral blood in an intensity-dependent manner, with numbers returning to baseline or lower during recovery. This mobilization of immune cells is explained in part by sympathetic activity and the release of stress hormones (catecholamines and cortisol). The literature examining immune responses to exercise has by and large failed to control for the presence of a warm-up prior to the experimental bout. Gradually increasing exercise intensity over a period of minutes may reduce the stress of the exercise bout and thus may influence the immune response to a given exercise protocol. PURPOSE: To …
