日本女性采珠者阿玛专门在寒冷的海水中自由潜水，采集食物和牡蛎中的珍珠。在水中运动结合明显的心动过缓和升压反应提供了循环挑战，以适当缓冲或缓冲升高的心脏搏动。由于Ama在其一生中反复进行自由潜水，因此它们可能已经适应了与潜水哺乳动物相似的动脉结构和功能。我们比较了日本采珠潜水员与生活在同一渔村的年龄匹配的身体不活跃的成年人的动脉硬度。对115名日本女性采珠者进行了研究。此外，还研究了居住在同一沿海村庄的50名身体不活跃的成年人和33名身体活跃的成年人（参加社区健身计划）。两组之间在年龄（~ 65岁）、体重指数和肱动脉血压方面没有差异。采珠者和体力活动活跃的成年人的动脉硬度、心踝血管指数和β硬度指数低于体力活动不活跃的同龄人（P < 0.05）。以心率75次/min调整后的增强压力和增强指数，采珠者明显低于其他组（P < 0.05）。这些结果表明，与生活在同一渔村的年龄匹配的身体不活跃的同龄人相比，终身日本采珠潜水员表现出动脉硬度和动脉波反射降低。
Japanese female pearl divers called Ama specialize in free diving in the cold sea for collecting foods and pearls in oysters. Exercising in the water combined with marked bradycardia and pressor responses provides a circulatory challenge to properly buffer or cushion elevated cardiac pulsations. Because Ama perform repeated free dives throughout their lives, it is possible that they may have adapted similar arterial structure and function to those seen in diving mammals. We compared arterial stiffness of lifelong Japanese pearl divers with age-matched physically inactive adults living in the same fishing villages. A total of 115 Japanese female pearl divers were studied. Additionally, 50 physically inactive adults as well as 33 physically active adults (participating in community fitness programs) living in the same coastal villages were also studied. There were no differences in age (∼65 yr), body mass index, and brachial blood pressure between the groups. Measures of arterial stiffness, cardio-ankle vascular index and β-stiffness index were lower (P < 0.05) in pearl divers and physically active adults than in their physically inactive peers. Augmentation pressure and augmentation index adjusted for the heart rate of 75 beats/min were lower (P < 0.05) in pearl divers than in other groups. These results indicate that lifelong Japanese pearl divers demonstrate reduced arterial stiffness and arterial wave reflection compared with age-matched physically inactive peers living in the same fishing villages.
