看见他们专业健身戴那种高原训练口罩，看了一些介绍说要先戴一次性口罩慢慢来，请问健身戴口罩有什么用？

可模仿高原低氧训练，增强心肺功能，提升表现。
高原训练是一种通过高海拔低氧环境来提升运动员耐力表现的方法。高原的空气比较稀薄，氧气分压下降，因此身体需要制造更多的红血球、血红素和肌红蛋白来提升摄氧能力。
在实际应用上，不少格斗比赛运动员/从事体能工作的朋友（如消防员） 均指出戴上口罩时的缺氧感觉更贴近真实比赛/工作环境，能提升专注度，克服心理恐惧。此外，适时加入新的训练元素也能提高运动的新鲜感和趣味性，打破常规，让身体有新的刺激。

高原训练法，运动训练方法之一。自1968年第19届奥运会赛址设在海拔高度为2240米的墨西哥城之后。高原训练法引起世界体育界的重视。
中度高原空气密度只有海拔平面的77%．氧含量只有平原地区的3/4左右，氧分压大于平原地区的20—25%、当运动员在这样的环境下进行训练时、由于"调节适应期"产生应激，呼吸频率和心率加快、溶解在血管里的部分氧气受低气压的影响不易被身体吸收。
使血管体积增大、血管扩张，血管壁增厚，血管变粗，通过的血量增多，从而更好地锻炼了运动员的心血管系统，提高了最大摄氧量和血色素浓度，增强了耐受乳酸的能力，产生了高原驯化（高原习服）。在返回平原时，失去了获得性适应性条件，运动员会产生新条件的应激，即晚驯化——脱服习。在大赛前进行高原训练．对运动成绩的提高效果员为显著。每次训练三周左右。

估计是为了增加无氧运动吧。现在口罩都比较闷气，健身时配带口罩可以使无氧运动增加，从而模拟高原缺氧的状态，模拟高原反应。这或许是健身口罩的作用。
不过这种口罩不适合平常状态下佩戴，会一定程度上阻塞血管，不适合长时间佩戴。如果是平常徒步和户外慢跑等有氧运动建议不佩戴口罩，可选择呼吸阻力较小的口罩或隐形口罩。我是一个对新奇事物比较好奇的人，在一些网站上看到过，好像叫什么普滤佳还是普滤+，记不得啦。
