This study aimed to investigate the effects of a marine exercise retreat program on thyroid-related hormone levels. A total of 62 middle-aged euthyroid women participated in a 6-day marine exercise retreat program. Using thyroid-stimulating hormone (TSH) and free thyroxine (fT4) hormone levels, the participants were divided into high and low-hormone-level groups. Despite decreased TSH and fT4 levels after the program, the factors influencing changes in each group were different. TSH levels were influenced by changes in the normalized low frequency (nLF) of heart rate variability and carbon monoxide (CO) from all the participants, and changes in body fat percentage, nLF, and nitrogen dioxide (NO) exposure level in the high TSH group. fT4 levels were influenced by changes in body mass index (BMI), NO exposure, and particulate matter diameter of 10 µm or less (PM) exposure in all participants. Changes in BMI and CO exposure influenced the low fT4 group. Lastly, changes in the exercise stress test affected the high fT4 group. Thus, the marine exercise retreat program affected euthyroid thyroid-related hormone levels, and influencing factors differ depending on the initial value of the hormone.
本研究旨在探讨海洋运动疗养对甲状腺相关激素水平的影响。共有 62 名中年甲状腺功能正常的女性参加了为期 6 天的海洋运动疗养。利用促甲状腺激素（TSH）和游离甲状腺素（fT4）激素水平，将参与者分为高激素水平组和低激素水平组。尽管该项目后 TSH 和 fT4 水平降低，但两组的影响因素不同。TSH 水平受心率变异性的归一化低频（nLF）和所有参与者的一氧化碳（CO）变化的影响，以及高 TSH 组的体脂百分比、nLF 和二氧化氮（NO）暴露水平的变化的影响。fT4 水平受所有参与者的体重指数（BMI）、NO 暴露和直径为 10 µm 或更小的颗粒物（PM）暴露的影响。BMI 和 CO 暴露的变化影响低 fT4 组。最后，运动应激测试的变化影响高 fT4 组。因此，海洋运动疗养会影响甲状腺功能正常的甲状腺相关激素水平，而影响因素则取决于激素的初始值。
