We determined whether a different approach of load\u2013velocity profiling affects the accuracy of estimating 1RM.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Predictions based on a practical 2-point approach (no pre-determination of 1RM) were compared to those obtained with the conventional multipoint and 2-point approach (pre-determination of 1RM). 1RM was estimated relying on a reference minimum velocity threshold (MVT) of 0.3\u00a0ms<jats:sup>\u22121<\/jats:sup>. Analyses were conducted for separate back-squat variations (<jats:italic>n<\/jats:italic>\u2009=\u200913 Smith machine; <jats:italic>n<\/jats:italic>\u2009=\u200913 free-weight). Slopes and y-intercepts were compared. The accuracy of 1RM prediction was determined by contrasting actual vs. predicted 1RM values.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The individual MVT did not differ from the general 0.3\u00a0ms<jats:sup>\u22121<\/jats:sup> value in either back-squat variation. Slopes and y-intercepts were similar between all determination approaches. For the Smith machine, estimated 1RM did not differ from the actual value with either approach (mean misestimate: \u22121.83 to 0.02\u00a0kg). However, the limits of agreement were wide (~\u200912\u00a0kg) and the absolute percent error was significantly different from 0 with all approaches (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>1RM can be estimated with similar accuracy with all profiling methods, irrespectively of the back squat variation.
