Reliability of the velocity achieved during the last repetition of sets to failure and its association with the velocity of the 1-repetition maximum.

Although these results suggest that V last could be a better indicator of the minimal velocity threshold than V 1RM, the low reliability of V last and the similar values of V last for both BP variants suggest that a standard V 1RM should be used to estimate the 1RM from the individualized load-velocity relationship.
