6分钟步行距离（6MWD）预测值主要来自单个国家的小队列。本研究的目的是调查国家之间的差异，并确定新的参考值，以提高6MWD的解释。我们研究了来自7个国家（10个中心）的444名受试者（238名男性），年龄在40-80岁之间。我们测量了6MWD、身高、体重、肺活量、心率（HR）、6分钟步行试验期间最大HR (HRmax) /预测最大HR （HRmax % pred）、Borg呼吸困难评分和氧饱和度。平均+/- SD 6MWD为571 +/- 90 m（范围380-782 m）。男性比女性多走30米(p
The 6-min walk distance (6MWD) predicted values have been derived from small cohorts mostly from single countries. The aim of the present study was to investigate differences between countries and identify new reference values to improve 6MWD interpretation.We studied 444 subjects (238 males) from seven countries (10 centres) ranging 40-80 yrs of age. We measured 6MWD, height, weight, spirometry, heart rate (HR), maximum HR (HRmax) during the 6-min walk test/the predicted maximum HR (HRmax % pred), Borg dyspnoea score and oxygen saturation.The mean +/- SD 6MWD was 571 +/- 90 m (range 380-782 m). Males walked 30 m more than females (p
