Validity of the 1RM equations with stop technique: a new approach
Abstract
This study validates new regression equations to estimate the value of the absolute maximum dynamic strength (1RM) by means of a maximum number of repetitions test to muscular failure (nRM) executed with stop technique. Also, this study assesses the validity of the equations that are already stablished in the international publications to estimate the load (% 1RM) and the 1RM value from a nRM test in executions with stop technique. The results indicate that the new equations proposed in this research [Bench Press 1RM = weight lifted in kg (-0,01841*nRM)+0,981; Full Squat 1RM = weight lifted in kg (-0,01176*nRM)+0,975] show substantially better validity levels (SEM = 1,8-2,2 kg; R2 = 0,956-0,988), and therefore of greater predictive ability, than the rest of equations described in the international literature to date.
