Acute Effect of Resistance Exercise on Red Blood Cells (RBC), Red Blood Cell Distribution Width (RDW) and Mean Corpuscular Volume (MCV) Among Physically Trained Boys

Abstract

Introduction: In this research, the examination of the acute effect of resistance exercise on Red blood cell (RBC), Red blood cell distribution width (RDW) and mean corpuscular volume (MCV) of physically trained boys has been aimed. Methods: Ten (10) physical education male students with an average age of 23.16±1.85 years participated in this study on voluntary basis. Red blood cell (RBC), Red blood cell distribution width (RDW) and mean corpuscular volume (MCV) of the students were analyzed before exercise (Pre-test) and just after 35 minutes of resistance exercise (Post-test). In order to determine all those hematological parameters, blood samples with 5 ml EDTA were taken from the forearm ante-cubical area before and after resistance exercise, and analyzed in laboratory with using auto-analyzer (Sysmex XP- 100). Result: Measurement results were presented as average and standard deviation. Student T-test for dependent samples was used in order to make a comparison between BE and AE values. P<-0.01 value was considered to be significant. The result of the study revealed that, the increase in AE than BE values for Red blood cell (RBC), Red blood cell distribution width (RDW) and mean corpuscular volume (MCV) significantly. Conclusion: Conclusively, red blood cell (RBC) count, red cell distribution width (RDW), and mean corpuscular volume (MCV) increased significantly following acute resistance exercise in physically active males.
