Hematological changes were studied in physically fit young soldiers who marched 35 km/d for 6 d, working at 35% of their Vo2 max. Four days of marching produced decreases in numbers of erythrocytes (RBC) and in hematocrit (Hct). This "sports anemia" persisted beyond day 6 into the post-march period and was accompanied by decreases in hemoglobin (Hb), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and mean corpuscular volume (MCV). The latter decrease was attributed to a preferential destruction of large RBC. The post-march period was characterized by an early (2 d) recovery of RBC numbers, Hct, and MCV, and a persistent (greater than 4 d) decrease in Hb, MCH, and MCHC. This pattern, characteristic of hypochromic macrocystosis, possibly reflects a premature release of young RBC from the bone marrow. Clearly, "Sports anemia," previously reported to occur with intensive physical exercise, can also result from sustained and repetitive submaximal exercise.
对身体健康的年轻士兵进行了血液学变化研究，这些士兵以其最大摄氧量的35%的强度，每天行军35公里，持续6天。行军4天后，红细胞（RBC）数量和血细胞比容（Hct）下降。这种“运动性贫血”在第6天之后持续到行军后阶段，并伴有血红蛋白（Hb）、平均红细胞血红蛋白（MCH）、平均红细胞血红蛋白浓度（MCHC）和平均红细胞体积（MCV）的下降。后者的下降归因于大红细胞的优先破坏。行军后阶段的特点是红细胞数量、血细胞比容和平均红细胞体积早期（2天）恢复，而血红蛋白、平均红细胞血红蛋白和平均红细胞血红蛋白浓度持续（超过4天）下降。这种低色素大细胞性贫血的模式可能反映了年轻红细胞从骨髓的过早释放。显然，先前报道的高强度体育锻炼时发生的“运动性贫血”也可能由持续和重复的次最大运动引起。
