Load-velocity Relationship for 1rm Prediction

Jidovtseff, B, Harris, NK, Crielaard, J-M, and Cronin, JB. Using the load-velocity relationship for 1 RM prediction. J Strength Cond Res 24(x): 000-000, 2009-The purpose of this study was to investigate the ability of the load-velocity relationship to accurately predict a bench press 1 repetition maximum (1 RM). Data from 3 different bench press studies (n = 112) that incorporated both 1 RM assessment and submaximal load-velocity profiling were analyzed. Individual regression analysis was performed to determine the theoretical load at zero velocity (LD0). Data from each of the 3 studies were analyzed separately and also presented as overall group mean. Thereafter, correlation analysis provided quantification of the relationships between 1 RM and LD0. Practically perfect correlations (r = ~0.95) were observed in our samples, confirming the ability of the loadvelocity profile to accurately predict bench press 1 RM.
