在威德尔海豹潜水期间，发现血红蛋白浓度和红细胞压积显著增加，可能是继发于脾收缩。我们试图了解这部分潜水反应是否存在于专业的人类屏气潜水员中。在重复屏气潜水至. apprx之前和之后超声测量脾脏大小。10名韩国女潜水员和3名日本男潜水员在6米深的水下进行屏气潜水。静脉血红蛋白浓度和红细胞压积的测量在九个美国宇航局和所有日本潜水员。在AMA中，脾脏长度和宽度在潜水后减小（分别为P = 0.0007和0.0005），计算出的脾脏体积减小19.5 ± 0.05。8.7%（平均值±）SD，P = 0.0002）。血红蛋白浓度和红细胞压积增加9.5 ±。5.9%（P = 0.0009）和10.5 ±。4%（P = 0.0001）。在日本男性潜水员中，脾脏大小和红细胞压积不受重复屏气潜水的影响，血红蛋白和浓度仅略高于基线（3.0 ± 0.5）。0.6%，P = 0.0198）。韩国阿马犬屏气潜水时发生脾收缩和红细胞压积增加。
Major increases of hemoglobin concentration and hematocrit, possibly secondary to splenic contraction, have been noted during diving in the Weddell seal. We sought to learn whether this component of the diving response could be present in professional human breath-hold divers. Splenic size was measured ultrasonically before and after repetitive breath-hold dives to .apprx. 6-m depth in ten Korean ama (diving women) and in three Japanese male divers who did not routinely practice breath-hold diving. Venous hemoglobin concentration and hematocrit were measured in nine of the ama and all Japanese divers. In the ama, splenic length and width were reduced after diving (P = 0.0007 and 0.0005, respectively) and calculated splenic volume decreased 19.5 .+-. 8.7% (mean .+-. SD, P = 0.0002). Hemoglobin concentration and hematocrit increased 9.5 .+-. 5.9% (P = 0.0009) and 10.5 .+-. 4% (P = 0.0001), respectively. In Japanese male divers, splenic size and hematocrit were unaffected by repetitive breath-hold diving and hemoglobin and concentration increased only slightly over baseline (3.0 .+-. 0.6%, P = 0.0198). Splenic contraction and increased hematocrit occur during breath-hold diving in the Korean ama.
