abstract = {This study compared the accuracy of the fastest mean velocity from set (MVfastest) to predict the
maximum number of repetitions to failure (RTF) between 2 variants of prone bench pull (PBP)
exercise (Smith machine and free-weight) and 3 methods (generalized, individualized multiplepoint,
and individualized 2-point). Twenty-three resistance-trained males randomly performed
2 sessions during Smith machine PBP and 2 sessions during free-weight PBP in different weeks.
The first weekly session determined the RTF-MVfastest relationships and subjects completed single
sets of repetitions to failure against 60-70-80-90%1RM. The second weekly session explored the
accuracy of RTFs prediction under fatigue conditions and subjects completed 2 sets of 65%1RM
and 2 sets of 85%1RM with 2 min of rest. The MVfastest associated with RTFs from 1 to 15 were
greater for Smith machine compared to free-weight PBP (F ≥ 42.9; P < 0.001) and for multiplepoint
compared to 2-point method (F ≥ 4.6; P ≤ 0.043). The errors when predicting RTFs did not
differ between methods and PBP variants, whereas all RTF-MVfastest relationships overestimated
the RTF under fatigue conditions. These results suggest that RTF–MVfastest relationships present
similar accuracy during Smith machine and free-weight PBP exercises and it should be constructed
under similar training conditions.},
