THE EFFECTS OF ENDURANCE TESTS ON BLOOD PARAMETERS IN PROFESSIONAL BADMINTON PLAYERS

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
