20 male elite long distance runners were compared to a control group of blood donors to determine the effect of training on red blood cells. The acute effects of exercise on red cells were investigated in 11 of the runners following a race of 15-30 km. The runners had elevated resting values of red cell 2,3-DPG (P less than 0.05) and mean cell volume (P less than 0.01); blood Hb and ATP were not different from concentrations in the control group. The red cell status of the athletes may be explained by an increased proportion of young erythrocytes in runners. No statistically significant changes in red cell 2,3-DPG, ATP, mean cell volume or blood Hb were found post exercise.
将20名男性精英长跑运动员与一组献血者对照组进行比较，以确定训练对红细胞的影响。在11名运动员跑完15 - 30公里的比赛后，研究了运动对红细胞的急性影响。运动员静息时红细胞2,3 - 二磷酸甘油酸（2,3 - DPG）值升高（P < 0.05），平均红细胞体积升高（P < 0.01）；血液血红蛋白（Hb）和三磷酸腺苷（ATP）浓度与对照组无差异。运动员的红细胞状态可能是由于跑步者中年轻红细胞比例增加所致。运动后红细胞2,3 - DPG、ATP、平均红细胞体积或血液Hb未发现有统计学意义的变化。
