The 6-min walk distance (6MWD) correlates well with functional capacity. However, previous reference equations for the 6MWD have failed to accurately predict the 6MWD due to variations in population ethnicity and geography.
The aims of this study were 1) to measure 6MWD in healthy North Indian adult males, 2) to determine the applicability of Enright and Sherrill's reference equation to healthy North Indian adult males, and 3) to develop a regression equation for Indian males.
After physical examination and investigations, the 6-minute walk test was conducted in male subjects aged 40-60 years.
The mean (±SD) 6MWD was 536.1 ± 46.9 m. Enright and Sherrill's reference equation did not correctly predict distance in an Indian population: walk distance was overestimated by a mean (±SD) of 46.8 ± 32.9 m. The regression equation developed for males was 6MWD (m) = 3.654 × height (cm) - 4.139 × age (years) + 127.121, and accounted for 63.9% of total variance.
Enright and Sherrill's equation cannot be used to predict the 6MWD in healthy North Indian adult males. The new regression equation is expected to prove useful for various purposes in healthy North Indian adult males.
6 分钟步行距离（6MWD）与功能能力密切相关。然而，由于人群种族和地理位置的差异，以前的 6MWD 参考方程未能准确预测 6MWD。
本研究旨在：1）测量健康的北印度成年男性的 6MWD；2）确定 Enright 和 Sherrill 的参考方程是否适用于健康的北印度成年男性；3）为印度男性制定回归方程。
在体格检查和检查后，对 40-60 岁男性进行 6 分钟步行测试。
6MWD 的平均值（±SD）为 536.1 ± 46.9m。Enright 和 Sherrill 的参考方程不能正确预测印度人群的距离：步行距离平均高估（±SD）为 46.8 ± 32.9m。为男性制定的回归方程为 6MWD（m）= 3.654×身高（cm）- 4.139×年龄（岁）+ 127.121，占总方差的 63.9%。
Enright 和 Sherrill 的方程不能用于预测健康的北印度成年男性的 6MWD。新的回归方程有望在健康的北印度成年男性中用于各种目的。
