The purpose of this study was to develop an equation to estimate maximum strength (1-RM) in elderly adults based on anthropometric and strength parameters. Initially, 20 subjects participated in the first equation (E1). Fifteen of the 20 completed the 12 wks of resistance training (RT). They were included in the second equation (E2). Anthropometric variables were measured pre- and post-intervention as were maximum dynamic strength (1-RM), number of repetitions (Reps), and Total Work (TW) of the maximum repetitions test (X-RM). The relationship between anthropometric, Reps, TW, and 1-RM were analyzed using Pearson’s correlation. Backward multiple regression analyses were used to determine the independence and mutual contribution from anthropometric and X-RM parameters to predict 1-RM with P<0.001), as did E2 (R² = 0.830; P<0.001). The findings can be used to safely determine 1-RM.
