This study aimed to determine the optimal inter-set rest periods that would maximize the number of repetitions completed before surpassing various cut-off velocities (COVs) during the prone bench pull exercise. Twenty-three physically active individuals, 15 men and 8 women, participated in six random testing sessions. Each session included four sets of the prone bench pull exercise performed with maximum intent on a Smith machine at 75% of the one-repetition maximum (1RM). The length of the inter-set rest interval (1 [R1], 3 [R3], and 5 [R5] min) and COV used (0.65 m•s [COV] and 0.55 m•s [COV]) varied between sessions. Longer inter-set rest periods led to a higher volume of repetitions (R5 > R3 > R1), whereas the differences between the rest protocols were larger for COV (R1: 28.4 ± 6.0 repetitions; R3: 36.4 ± 9.4 repetitions; R5: 41.1 ± 11.4 repetitions) compared to COV (R1: 24.2 ± 7.3 repetitions; R3: 25.4 ± 10.1 repetitions; R5: 28.3 ± 9.7 repetitions). Increasing the number of sets negatively impacted the number of completed repetitions for R1 using both COV and COV, as well as for R3 using COV. The fastest velocity of the set (MV) did not differ between the inter-set rest protocols for COV, while for COV, R3 and R5 provided a greater MV than R1 for sets 2-4. These findings suggest that the duration of inter-set rest periods is an important factor to consider when aiming to maximize mechanical performance across multiple sets of the prone bench pull exercise.
本研究旨在确定在俯卧凳拉练习中，能使在超过不同截止速度（COV）之前完成的重复次数最大化的最佳组间休息时间。23名身体活跃的个体，15名男性和8名女性，参加了六次随机测试 session。每个session包括四组在史密斯机上以最大努力进行的俯卧凳拉练习，强度为一次重复最大值（1RM）的75%。组间休息间隔的时长（1分钟[R1]、3分钟[R3]和5分钟[R5]）以及使用的COV（0.65米·秒[COV]和0.55米·秒[COV]）在不同session中有所变化。更长的组间休息时间会导致更高的重复次数（R5 > R3 > R1），而与0.55米·秒的COV相比，对于0.65米·秒的COV，不同休息方案之间的差异更大（R1：28.4 ± 6.0次重复；R3：36.4 ± 9.4次重复；R5：41.1 ± 11.4次重复） 相较于0.55米·秒的COV（R1：24.2 ± 7.3次重复；R3：25.4 ± 10.1次重复；R5：28.3 ± 9.7次重复）。增加组数对使用0.65米·秒的COV和0.55米·秒的COV时R1的完成重复次数以及使用0.65米·秒的COV时R3的完成重复次数产生负面影响。对于0.65米·秒的COV，组间休息方案之间每组的最快速度（MV）没有差异，而对于0.55米·秒的COV，在第2 - 4组中，R3和R5的MV比R1更大。这些发现表明，当旨在使多组俯卧凳拉练习的机械性能最大化时，组间休息时间的长短是一个需要考虑的重要因素。
