Abstract/Description:
This study examined the accuracy of predicting back squat and bench press one repetition maximum (1RM) from submaximal average concentric velocity (ACV).Seventeen resistance trained men performed a warm-up and 1RM test on the squat and bench press, in which ACV was assessed on all repetitions. The ACVs during the warmup closest to 1.0 and 0.5 m.s-1 were used in a 2-point linear regression forecast of 1RM and the ACVs established at the loads closest to 20, 50, 70, and 80% of 1RM were used in a 4-point 1RM prediction. An ANOVA indicated significant differences between predicted and actual 1RM for all predictions (p<0.001). Both Bland-Altman and Mountain plots confirmed the findings of the ANOVA as data were not tightly conformed to the respective zero difference lines. Therefore, these results suggest that a linear regression forecast using submaximal ACV does not accurately predict 1RM in the ¬back squat and bench press.
