Effect of Resistance Training on the Accuracy of Predicting 1-RM Bench Press From Repetitions

The purpose of this study was to evaluate the accuracy of predicting maximal bench press strength (1-RM) from submaximal load and repetitions following training in high- and low-strength college men. High-strength (HS, n = 56) and low-strength (LS, n = 58) men were measured for 1-RM, submaximal repetition load, and repetitions before training. The same measurements were assessed again following 12 weeks of resistance training. Multiple regression analysis at pre-training allowed accurate prediction of 1-RM (R2 = 0.92, SEE = 5.9 kg). After training, the absolute strength gains made by both groups were not significantly different while the percent gain was significantly less for the HS group than for the LS group. The difference between predicted and actual post-training 1-RM was significantly greater for the HS group than for the LS group. Similar resistance training programs are likely to have slightly different effects on HS and LS men.
