| Summary: | Introduction:The aim of the present study is to investigate the variations of hematological parameters following two bouts of selected concurrent endurance and resistance exercises in one day.Material and Methods:Eight male students of physical education in Guilan University volunteered for our study. The participants performed concurrent endurance-resistance exercises for 90 minutes in the morning and afternoon bouts. Blood samples were obtained before, immediately after and three hours after the exercise to measure for hematological parameters – white blood cell, red blood cell, hemoglobin, hematocrit, mean hemoglobin concentration, mean corpuscular volume, platelet, and plasma volume. The participants were fasting for at least 12 hours prior to the first blood sampling. We used analysis of variance with repeated measures and Bonferroni’s post hoc test to evaluate the hematological variations, with p values ≤ 0.05 considered significant.Results:Our findings indicate that white blood cell and platelet counts increased significantly three hours after, and immediately after exercise, respectively. Furthermore, hematocrit, hemoglobin, and red blood cell counts decreased significantly three hours after exercise (p<0.05). However, no significant variations were observed for MCH, MCHC, MCV and PV parameters (p>0.05).Conclusion:Considering the fall in blood factors essential for gas exchange and its possible impact on oxygenation of active muscles, as well as the rise in coagulative and immunity factors following two bouts of exercise, trainers and athletes are advised to be wary about the impacts of performing concurrent and repeated exercises in one day. |
