Background: The 1-minute sit-to-stand test (1min-STST) is a field test to assess physical capacity, usually when the 6-minute walk test (6MWT) is not possible to perform. However, normal values are lacking for the Argentine population. For this reason, our objective was to establish reference values for the Argentine population of 1min-STST.
Methods: We performed a multicentric cross-sectional study. Healthy adults between 18 and 80 years in six cities of Argentina (Paraná, Ushuaia, Tandil, Catamarca, Mendoza y Capital Federal) completed the 1min-STST.  The test was performed with a standard height chair (46 cm) without armrests positioned against a wall. The primary outcome was the number of repetitions. Additionally, were registered demographic, anthropometric and physiologic variables during the test.
Results: We included 304 healthy subjects, 154/150 female/male, mean age of 48±15 years, mean height of 169±9 cm, and mean weight of 75±15 Kg. The median of repetitions was 37 (P25-P75, 29-46), and 35 (P25-P75, 28-44) for males and females, respectively. The specific values by sex and age range are shown in Table 1. The only variable that significantly correlated with the number of repetitions was age (r -0.494, p<0.001).
Conclusion: In this study, we determined reference values for the 1min-STST in healthy adults in Argentine. There was a correlation between 1min-STST and age.
