: 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). : 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. : The mean grip width used by participants was 20.04% higher in the free grip width condition ( < .001). There were similar results in the 1RM ( = .954), repetitions to failure test ( = .117), and power-force-velocity profile ( > .05) in both grip width conditions. A stronger relationship was observed between 1RM and repetitions to failure test during the biacromial ( = 0.720; < .001) with respect to the free grip width ( = 0.607; = .002). : 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.
本研究旨在探讨握距对引体向上(PU)运动中力量-功率-速度特征、最大力量和重复至力竭测试表现的影响。 14 名训练有素的男性使用双肘宽距和自由握距进行递增负荷和重复至力竭测试。确定功率-力量-速度关系、1RM 和完成的重复次数。 参与者在自由握距条件下的平均握距高 20.04%(<0.001)。在两种握距条件下,1RM(=0.954)、重复至力竭测试(=0.117)和功率-力量-速度特征(>0.05)均具有相似的结果。与自由握距相比,双肘宽距条件下 1RM 和重复至力竭测试之间的关系更强(=0.720;<0.001)(=0.607;=0.002)。 因此,在 PU 运动中,选择自由握距或双肘宽距不会影响最大力量、力量-功率-速度关系或重复至力竭次数。
