Abstract

Purpose: Physical inactivity is considered an important risk factor for osteoporosis, however, some athletes performing extremely high training volumes can also develop bone mass loss. Moreover, the effect of total body mass or body surface area on bone mineral density remains controversial. Therefore, the aim of this study was to compare the absolute bone mineral density and bone mineral density adjusted to body surface area between amateur triathletes and nonactive women.

Methods: Forty-two healthy women (23 amateur triathletes and 19 nonactive individuals) were evaluated for body composition using a dual-energy X-ray absorptiometry system.

Results: Compared to nonactive women, amateur triathletes exhibited lower body mass index (p < 0.001), lower bone mineral density (p < 0.001), and body surface area (p < 0.001). However, bone mineral density adjusted by body surface area in the triathletes was higher than in the nonactive women (p = 0.03).

Conclusion: These findings showed that amateur triathles presented lower absolute bone mineral density, but higher bone mineral density adjusted to body surface area. Future studies are recommended to identify if the higher bone mineral density adjusted to body surface area are associated with a lower bone fragility.

业余铁人三项女运动员与非运动员骨质密度的比较：横断面研究

目的：缺乏运动被认为是骨质疏松症的一个重要风险因素，然而，一些进行超高训练量的运动员也会出现骨质流失。此外，总体重或体表面积对骨矿物质密度的影响仍存在争议。因此，本研究旨在比较业余铁人三项运动员和非运动员女性的绝对骨矿物质密度和根据体表面积调整后的骨矿物质密度：方法：使用双能 X 射线吸收测量系统对 42 名健康女性（23 名业余铁人三项运动员和 19 名非运动员）的身体成分进行评估：结果：与非运动女性相比，业余铁人三项运动员的体重指数较低（p p p = 0.03）：这些研究结果表明，业余铁人三项运动员的绝对骨矿物质密度较低，但根据体表面积调整后的骨矿物质密度较高。建议今后开展研究，以确定根据体表面积调整的较高骨矿物质密度是否与较低的骨脆性有关。
