Key result
Long-term cold water diving among Jeju female divers was associated with significantly lower right-femoral pulse wave velocity and a higher ankle-brachial index compared to normal same-aged women.
Why the study?
Does long-term cold water diving without oxygen assistance affect arterial stiffness in Jeju female divers compared to normal women?

Does long-term cold water diving without oxygen assistance affect arterial stiffness in Jeju female divers compared to normal women?
Long-term cold water diving in Jeju female divers is associated with lower arterial stiffness compared to age-matched controls, suggesting vascular adaptation to their unique physical activity and environment.
May indicate vascular adaptation in divers without supporting practice change; leaves open causal effects and need for prospective confirmation.
In this study, we tried to analyze arterial stiffness of Jeju female divers who diver into cold water without the assistance of oxygen. For this purpose we measured pulse wave velocity and ankle-brachial index of Jeju female divers and same aged females who didn't have any cardiovascular risk for comparing the vascular stiffness. The results were the following : First, the light-femoral pulse wave velocity of Jeju female divers was significantly lower than normal women of the same ages. Second, Jeju female divers's ABI showed higher tendency than normal same aged women. These result showed that Jeju female divers' body had been completed for adaptation to low temperature and high pressure water environment through a long-term immersion activities in old age, as well as due to higher physical activity levels of Jeju female divers peripheral vascular resistance was not reduced.
