One of the most used methods for measuring muscular strength is the one repetition maximum test (1-RM), since its versatility for use in different exercises, its specificity of movement and low operating cost. Despite the advantages, some questions remain unclear. In this study we discuss about the available evidences regarding safety, reproducibility, intervenient factors and the practical applicability of the 1-RM test. The available evidence suggests that the 1-RM test is cardiovascular and orthopedic safely and Its reliability depends on the appropriate test procedures used for load stabilization as well as the control of intervenient factors that may influence the test performance. Although the applicability for the diagnosis and monitoring of muscular strength is large, the use of the 1-RM tests for the prescription of weight training is highly debatable.
