The aim of this study was to determine the level of agreement between estimation equations with the 1RM method in a sample of 30 experienced young people. Four exercises were performed: barbell squat (SQ), horizontal bench press (BP), dead weight (DW), and military press (MiP), with a minimum and a maximum of 1 to 7 repetitions respectively. Six prediction equations were considered: Brzycki (1993), Epley (1995), Lander (1985), Cummings and Finn (1998), O'Conner et al. (1989), and Abadie et al. (1999). The mean and standard deviation were calculated, as well as the level of intraclass correlation and the Bland-Altman method to study the association. The mean values of 1RM obtained very good correlation in the equations of Brzycki (1993) and O'Conner et al. (1989) in the SQ, Epley (1995) in the BP exercise, and Cummings and Finn (1998) in the DW exercise. The predictive equation of Cummings and Finn (1998) and Epley (1995) can also be used to calculate 1RM in MiP. To improve the dosage of loads, it is recommended to use the predictive equations according to the exercise to be performed.
