The optimal minimum-velocity threshold (MVT) was recently\n                    proposed to increase the accuracy of 1RM predictions. Individual load-velocity\n                    profiles (LVP) were obtained in 18 athletes enrolled in recreational soccer.\n                    Reliability analyses were computed for all LVP-derived variables. Estimations of\n                    1RM were made based on general (0.3\u2009m.s\u2212\u20091), pre-individual (mean\n                    velocity at 1RM obtained in a preliminary session) and optimal MVT (velocity\n                    that eliminates the difference between actual and predicted 1RM, determined in a\n                    preliminary session). The accuracy of 1RM predictions was examined using\n                    absolute-percent error and Bland-Altman plots. Between-day reliability of the\n                    LVP and 1RM was good (intraclass-correlation coefficients \u2013 ICCs&gt;0.9 and\n                    coefficients of variation \u2013 CVs&lt;5%). The individual and optimal MVT reached\n                    moderate-to-good reliability (ICCs&gt;0.9 and CVs&lt;10%, respectively). The\n                    predictions based on the optimal MVT displayed greater accuracy than those\n                    obtained with the individual and general MVT (absolute percent error: 2.8 vs.\n                    5.5 vs. 4.9%, respectively). However, wide limits of agreement (LoA) were found\n                    between actual and estimated 1RM using this approach (~15\u2009kg). Data indicate\n                    that the optimal MVT provides better estimations of 1RM for the free-weight back\n                    squat than the general and the individual MVT.<\/jats:p>","DOI":"10.1055\/a-2335-4143","type":"journal-article","created":{"date-parts":[[2024,7,28]],"date-time":"2024-07-28T22:30:31Z","timestamp":1722205831000},"page":"923-929","source":"Crossref","is-referenced-by-count":7,"title":["Optimal
