Peripheral blood leukocyte subsets are mobilized distinctly upon two different types of exercise. Blood samples were collected from 15 subjects at the indicated time points after maximal and endurance exercises. Leukocytes were enumerated by flow cytometry. Eight major subsets are shown: granulocytes, lymphocytes, monocytes, Natural Killer (NK) cells, B cells, T cells including CD4⁺ and CD8⁺ subsets. For each subset, the means were significantly different (p < 0.0001 by repeated measures ANOVA). ** = p <0.01 by the Bonferroni’s multiple comparison post-test of all pairs
