There are no references equations for Spanish population. The aim was to develop reference equations to predict the total distance walked (ISWD) in the ISWT in 45-85 years healthy population from different geographic areas of Spain.Cross-sectional multicenter study carried out in 17 Spanish hospitals and universities. Sociodemographic, toxic habits, regular medication, medical history, anthropometric, habitual physical activity, and exercise capacity data were collected.568 healthy subjects (48% male) were assessed, mean(SD) age 62(11) years, height 164(10) cm, weight 74(13) kg, body mass index (BMI) 27(4) kg/m2, distributed: Andalucía 8% of subjects, Aragon 5%, Asturias 6%, Catalunya 33%, Galicia 8%, Illes Balears 10%, Islas Canarias 4%, Madrid 18% and Murcia 7%. The ISWD (best of two tests) was mean(SD) 632(191) and 497(154) meters for men and women, respectively. The derived reference equations were: for men, IWSD=838-(11.3xage)+(5.87xheightcm)-(3.44xweightkg)-(3.16xHRbaseline*)+131, and for women, IWSD=1291-(9.66xage)-(2.9xweightkg)+106. The resulting equations explained 53% of the variance in the ISWD in healthy Spanish both men and women. * HRbaseline*: baseline heart rate.The variability in the ISWD can be explained from the age, height, weight and baseline HR in men; and the age and weight in women. The equations derived from this study are applicable to Spanish population to predict the theoretical ISWD. Next steps will be to validate these reference equations in subjects with respiratory disease. ER -
