This study was undertaken to examine the role of interset stretching on the time course of acceleration portion AP and mean velocity profile during the concentric phase of 2 bench-press sets with a submaximal load (60% of the 1 repetition maximum). Twenty-five college students carried out, in 3 different days, 2 consecutive bench-press sets leading to failure, performing between sets static stretching, ballistic stretching, or no stretching. Acceleration portion and lifting velocity patterns of the concentric phase were not altered during the second set, regardless of the stretching treatment performed. However, when velocity was expressed in absolute terms, static stretching reduced significantly (p <0.05) the average lifting velocity during the second set compared to the first one. Therefore, if maintenance of a high absolute velocity over consecutive sets is important for training-related adaptations, static stretching should be avoided or replaced by ballistic stretching.
本研究旨在探讨在进行两组次最大负荷（1 重复最大值的 60%）的卧推时，中间间隔拉伸对向心阶段加速段 AP 和平均速度曲线的影响。25 名大学生在 3 天内连续完成了两组导致失败的卧推，每组之间分别进行静态拉伸、弹振拉伸或不拉伸。无论采用哪种拉伸处理，第二组的向心阶段加速段和提升速度模式都没有改变。然而，当速度以绝对值表示时，与第一组相比，静态拉伸显著降低了第二组的平均提升速度（p<0.05）。因此，如果要在连续的几组中保持较高的绝对速度对于训练相关的适应很重要，那么静态拉伸应该避免或被弹振拉伸取代。
