Population aging requires the elaboration of public policies that guarantee access to health, quality of life for the elderly; Thus, the city of Rio de Janeiro created the Rio Outdoor project, which uses outdoor fitness centers to conduct physical exercises in city squares. Although organized, the project does not have a tool to evaluate the physical fitness of the elderly. The objective of this study was to validate a submaximal field test that evaluates the cardiorespiratory condition of elderly people who attend the Rio Outdoor Project, using the specific equipment of the same. It was tested the hypothesis that the Outdoor Circuit Test-TCAL is valid for the project population. A literature search was carried out to verify if any already validated field test was adequate to the reality of the project. Seven studies were found, but none meets the needs and physical and structural realities of the project. In this way, a specific field test was validated, based on the circuit performed by the elderly in the specific equipment of the project. The concurrent validity was tested by correlation between the predicted VO2max through the model generated by the TCAL and the VO2max observed in the maximal stress test in cycloergometer, and obtained r = 0.64. The reproducibility of the circuit was tested by test and re-test and r = 0.93 was observed. The stepwise forward model yielded the following prediction equation (R2 = 0,41, SEE = 2,86 ml.kg-1.min-1, F (5,43) = 5,90, P <0,001): VO2max (ml.kg-1.min-1) = 38,77 - 4,11 (sex; M=0, F=1) -0,12 (Age, years) + 0,19 (BMI, kg.m2) 0,13 (time circuit, min) 0,13 (waist circumference, cm). In summary, the predictive model was able to explain 41% of variance in VO2max (moderate association), with an approximate error of 3 ml.kg-1.min-1. Despite the small contribution of the circuit execution time, the maintenance of this variable in the model is justified by the fact that it was able to increase the R2 and decrease the SEE. It is concluded that the proposed test can be considered valid and applicable to the Rio Outdoor project, presenting as a tool to evaluate the cardiopulmonary capacity of the elderly, for the use of professionals who participate in it
