STUDY OF THE EFFECT OF PHYSICAL TRAINING ON THE RED CELL DISTRIBUTION CURVES INFLUENCED FOR A MONTH / 体力科学

ABSTRACT

It was known that physical training caused temporary changes in property of erythrocytes in a trainee.<BR>The purpose of this study is to determine how physical training bring about changes in blood corpuscle on long-distance runners under training for a month. In addition, a comparative study of distribution curves of red blood cell and changes of blood corpuscle was investigated.<BR>The number of long-distance runner was twelve, throughout a regularly training program for a month.<BR>Blood corpuscle (RBC, WBC, Ht, MCV) were count by Coulter Counter, and the hemoglobin content was measured by the Hemoglobinometer. The red cell distribution curves were analyzed, using Coulter Channelyzer.<BR>The results obtained are as follow<BR>1) After the physical training, the macrocytes were decreased and microcytes were increased. Therefore red cell distribution curves shift to the left.<BR>2) Red blood cell count was not influenced by regular training over a month.<BR>3) MCV became markdly smaller between before and after the training, indicating a significance of p<0.01.<BR>4) The hemoglobin content increased between before and after the training, indicating a significance of p<0.05.<BR>5) It has been confirmed that hemoglobin content and density of a red blood cell was increased by the effect of physical training.
