Introduction: The National Rower Evaluation System [Sistema Nacional de Avaliação do Remador] (SNAR), adopted by the Brazilian Rowing Confederation, aims to establish a national ranking, and is a prerequisite to participation in National Championships and Selective Games, in its different categories, as well as for joining the Brazilian Rowing Team. Objective: This study aimed to analyze the relationship and the prediction of the SNAR results with competitors’ times in a Brazilian Rowing Championship (CBR). Methods: The investigation involved 11 female rowers (18.00 ± 0.89 years) and 16 male rowers (18.18 ± 0.91 years), participants in a CBR, in the junior category. The research was qualitative, with content analysis of the data available on the Confederation's website. Results: In the junior female category, of the ten variables studied, three showed a correlation r≥0.50; in the junior male category, nine showed a correlation r≥0.50. The multiple linear regression equation, with all the variables studied, showed R2 = 0.86 and SEE = 5.30, in the female category; and R2 = 0.90 and SEE = 3.56, in the male category. Conclusion: Based on our results, the tests indicated by SNAR can be an important source of information, offering significant support for managers, athletes and coaching staff, for use in performance diagnosis and in particular, competition prognosis. It can also be used to adapt training schedule where necessary. Level of evidence I; Diagnostic studies-Investigation of a diagnostic test.
