Abstract Background The six-minute walking test (6MWT) is a tool that plays key role in evaluating the functional exercise capacity, prognosis and evaluation of treatment response patients with various cardiopulmonary diseases. However, standard reference equations are currently unavailable for distance (6MWD) people aged 60–85 years China. purpose this study was to 1) measure 6MWD healthy Chinese years, 2) establish predicting 6MWD, 3) compare our reported previously published studies. Method We obtained informed consent from each participant prior test, research design approved by Ethics Committee Wenzhou People’s Hospital. demographic anthropometric data subjects old were measured using standardized protocol. Every subject completed two 6MWTs, longest further analyzed. Results Two hundred sixty-six (128 males 138 females) 6MWT, mean 518 ± 72 m. Males achieved longer than females (518 m vs. 487 70 m; p < 0.0001), active nonactive (512 76 485 63 0.0001). According univariate analysis, significantly associated age, height, body mass index (BMI), heart rate blood pressure after changes before exercise. stepwise multivariate regression analysis identified height BMI as independent predictors 6MWD. Caucasians South Americans tended overestimate subjects, while Asian African populations underestimate Conclusions This first describe prediction proposed. These findings will help improve diseases affect capacity.
