Abstract
It was known that physical training caused temporary changes in property of erythrocytes in a trainee.
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.
The number of long-distance runner was twelve, throughout a regularly training program for a month.
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.
The results obtained are as follow:
1) After the physical training, the macrocytes were decreased and microcytes were increased. Therefore red cell distribution curves shift to the left.
2) Red blood cell count was not influenced by regular training over a month.
3) MCV became markdly smaller between before and after the training, indicating a significance of p<0.01.
4) The hemoglobin content increased between before and after the training, indicating a significance of p<0.05.
5) It has been confirmed that hemoglobin content and density of a red blood cell was increased by the effect of physical training.
