Purpose: The objective of this study was to investigate the influence of the grip width on the power-force-velocity-profile, the maximal strength, and performance during a repetition to failure test in the pull-up exercise (PU). Method: Fourteen trained males performed an incremental loading and repetitions to failure test with the PU exercise using biacromial and free grip widths. Power-force-velocity relationship, 1RM, and repetitions completed were determined. Results: The mean grip width used by participants was 20.04% higher in the free grip width condition (p < 0.001). There were similar results in the 1RM (p = 0.954), repetitions to failure test (p = 0.117), and power-force-velocity profile (p > 0.05) in both grip width conditions. A stronger relationship was observed between 1RM and repetitions to failure test during the biacromial (R[superscript 2] = 0.720; p < 0.001) with respect to the free grip width (R[superscript 2] = 0.607; p = 0.002). Conclusion: Therefore, the choice of a free or a biacromial grip width does not affect the maximal strength, power-force-velocity relationship, nor the repetitions to failure during the PU exercise.
