Leukocytosis and lymphocyte counts (including subpopulations CD3, CD4, CD8, CD19, CD16) were determined in two groups of young athletes subjected to exercise tests. The "Acute exercise" group consisted of 25 sprinters who performed Wingate test, and the "Endurance" group consisted of 13 competitive middle-distance runners who performed graded endurance treadmill exercise. Venous blood for lymphocyte phenotyping was sampled before, immediately after and 30 min after having completed the exercise. The counts of leukocytes, lymphocytes and their subpopulations significantly increased in both groups immediately post-exercise and decreased to initial values 30 min later. The type of exercise test and, presumably, of training had no effect on changes in the blood cell counts. Verf.-Referat
