Abstract :Changes in hemorheological and microcirculatory parameters that occur during exercise and their possible consequences have attracted much attention recently. The aim of this study was to investigate the changes in blood parameters before, after and 24 hours after the Yo-Yo intermittent recovery test (YIRT1) in level 1 professional male badminton players. Sixteen professional male badminton players voluntarily participated in this study. Total blood counts, erythrocyte deformability and aggregation were evaluated in samples taken prior to and following the test and 24h after the completion of the test. During the test, the total distance was recorded. Erythrocyte deformability, evaluated under shear stresses of 0.53, 0.95, 1.69, 3.00, and 5.33 Pascal (Pa), showed a significant increase at the end of the test (p<0.05). Following the test, the aggregation index rose while erythrocyte accumulation decreased significantly (p<0.05). Hematocrit levels, hemoglobin concentrations, and erythrocyte counts also demonstrated significant increases immediately after the test (p<0.05), but these values were significantly lower 24 hours post-test compared to pre-test levels (p<0.05). Leukocyte parameters exhibited a marked increase relative to pre-test values (p<0.05). Additionally, thrombocyte counts displayed significant differences between pre-test, post-test, and 24-hour post-test measurements (p<0.05). Hemorheological changes increase parallel with exercise intensity and it continues after the exercise. YIRT1, which provides information about the physical capacities of the players, was found to affect the hemorheological parameters. In further studies, the possible effects of different exercise protocols can be examined by taking into account the roles of cellular factors (enzymes, hormones, oxidant stress) in hemorheological changes.
