Paired sets and alternative set configurations (e.g., cluster sets) are frequently employed by strength and conditioning practitioners; however, their synergistic impact remains underexplored in research. This study aimed to elucidate whether the set configuration used in a lower-body exercise affects mechanical performance during paired sets of upper-body exercises.
Twenty-one resistance-trained individuals (14 men and 7 women) randomly completed three experimental sessions that involved four sets of five repetitions at 75%1RM during both the bench press and bench pull exercises. The three experimental sessions varied solely in the activity conducted during the inter-set rest periods of each upper-body exercise: (i) Traditional squat - six squat repetitions without intra-set rest at 65%1RM; (ii) Rest redistribution squat - two clusters of three repetitions of the squat exercise at 65%1RM with 30 s of intra-set rest; and (iii) Passive rest - no exercise.
The rest redistribution set configuration allowed the sets of the squat exercise to be performed at a faster velocity than the traditional set configuration (p = 0.037). However, none of the mechanical variables differed between the exercise protocols neither in the bench press (p ranged from 0.279 to 0.875) nor in the bench pull (p ranged from 0.166 to 0.478).
Although rest redistribution is an effective strategy to alleviate fatigue during the sets in which it is implemented, it does not allow subjects to perform better in subsequent sets of the training session.
力量与体能训练从业者经常采用配对组和替代组配置（如集群组）；然而，它们的协同影响在研究中仍未得到充分探索。本研究旨在阐明在下半身运动中使用的组配置是否会影响上半身运动配对组期间的力学性能。
21名经过抗阻训练的个体（14名男性和7名女性）随机完成三个实验环节，在卧推和坐姿下拉练习中，以75%的1RM进行四组，每组五次重复。这三个实验环节的唯一区别在于每个上半身练习组间休息期间所进行的活动：（i）传统深蹲——以65%的1RM进行六次深蹲重复，组内无休息；（ii）休息重新分配深蹲——以65%的1RM进行两组，每组三次深蹲练习，组内休息30秒；（iii）被动休息——不进行运动。
休息重新分配组配置使得深蹲练习组的完成速度比传统组配置更快（p = 0.037）。然而，在卧推（p值范围为0.279至0.875）和坐姿下拉（p值范围为0.166至0.478）中，各运动方案之间的力学变量均无差异。
尽管休息重新分配是一种在实施过程中减轻组内疲劳的有效策略，但它并不能使受试者在后续训练组中表现得更好。
