摘要：In order to investigate the effects of physical training on red blood cell properties, in particular erythrocyte 2, 3-DPG, the present study was examined using 10 alpine skiers (Athlete) and 7 untrained persons (Control) aged from 19 to 26 years. The results were obtained as follows : 1) The average Vo2max value of Athlete was significantly higher than that of the Control. 2) With regards to the red blood cell properties (RBC, Hb, Hct), there was no significant difference between the two groups. However MCV, MCH values of Athlete were significantly Iower, and MCHC of Athlete was significantly higher in comparison with those of the Control. 3) The erythrocyte 2, 3-DPG concentration levels were significantly higher in Athlete as compared with those of Control. 4) The relationship between Vo2max and erythrocyte 2, 3-DPG was significantly correlated for all subjects composing the two groups. A significant correlation was also found between MCHC and erythrocyte 2, 3-DPG for the group of all Subjects. These results suggest that MCHC and erythrocyte 2, 3-DPG are closely correlated. Therefore, it is conceivable that improvement of aerobic work capacity as a physical training effect is because of the simultaneous increase of both MCHC and erythrocyte 2, 3-DPG and decrease in MCV.
