The authors previously reported that many of sports-player on a way of training tended to suffer form "Sports-anemia". This fact was confirmed in this paper by increasing its data. The authors obtained the following results by carrying on a few experiments on the relation between sports anemia and motor ability. 1) When a player was under the condition of anemic tendency, his maximum oxygen-intake and -debt were small and R. Q. in muscular exercise was high, as compared with normal condition. 2) In the rat from which the blood was drawn to cause anemia, its oxygen intake became less, the endurance worse, and R. Q. higher as anemia grew worse. 3) In person with superior stamina who was selected out of long-distance runners as a Ekiden (a long-distance race) runner, erythrocyte count was more and hemoglobin concentration was higher than those unselectee. 4) It is quite natural that the erythrocyte, above all hemoglobin, should participate in the transport of oxygen to tissue, However, the authors stressed here that the hypoproteinemia arise from anemia, which causes an increase in R. Q. and reduction in oxygen debt capacity, and it decreases the buffer capacity of protein and prmoted the buffer capacity of bicarbonate.
