Reliability of the velocity achieved during the last repetition of sets to failure and its association with the velocity of the 1-repetition maximum García Ramos, Amador Janicijevic, Danica González Hernández, Jorge M. Keogh, Justin W. L. Weakley, Jonathon Bench press Linear position transducer Minimal velocity threshold Strength testing Velocity-based training Background: This study aimed to determine the reliability of the velocity achieved during the last repetition of sets to failure (Vlast) and the association of Vlast with the velocity of the 1-repetition maximum (V1RM) during the paused and touch-and-go bench press (BP) exercises performed in a Smith machine. Methods: A total of 96 healthy men participated in this study that consisted of two testing sessions. A single BP variant (paused BP or touch-and-go BP) was evaluated on each session in a randomized order. Each session consisted of an incremental loading test until reaching the 1RM, followed by two sets of repetitions to failure against a load ranging from 75% to 90% of 1RM. Results: The reliability of Vlast was unacceptable for both BP variants (CV > 18.3%, ICC < 0.60). The correlations between V1RM and Vlast were small for the paused BP (r = 0.18) and moderate for the touch-and-go BP (r = 0.37). Conclusions: Although these results suggest that Vlast could be a better indicator of the minimal velocity threshold than V1RM, the low reliability of Vlast and the similar values of Vlast for both BP variants suggest that a standard V1RM should be used to estimate the 1RM from the individualized load-velocity relationship. 2020-04-15T11:45:40Z 2020-04-15T11:45:40Z 2020-03-11 info:eu-repo/semantics/article García-Ramos A, Janicijevic D, González-Hernández JM, Keogh JWL, Weakley J. 2020.
