This randomised controlled study examined the force-velocity relationship changes (force and velocity axis intercepts, slope and estimated maximum power) in response to 5-week training programmes differing in the set configuration. For each session, the traditional group performed 4 sets of 8 repetitions with 5 min of rest between sets and exercises, while the cluster group completed 16 sets of 2 repetitions with 1 min of rest between sets and 5 min between exercises. Both programmes were performed with the 10-repetition maximum load, including bench press, parallel squat, lat pull-down and leg curl exercises. Individual force-velocity profiles were obtained for bench press and squat using a linear velocity transducer before and after the intervention, along with lactate and mechanical performance during the intervention. Results showed in bench press similar changes of the force-velocity profile after both protocols (no shift of the slope and higher force and velocity axis intercept values). For the squat, significant changes in the slope (P = 0.001) and the velocity intercept (P = 0.002) towards a velocity profile were observed after cluster but not after traditional training. These results suggest that set configuration may modulate changes of force-velocity relationship, especially for squat.
这项随机对照研究考察了在不同的组间配置的 5 周训练计划中，力-速度关系变化（力和速度轴截距、斜率和估计最大功率）。对于每个训练组，传统组进行了 4 组 8 次重复，每组之间休息 5 分钟，每组之间和每组之间休息 1 分钟，而集群组完成了 16 组 2 次重复。两组都使用 10 次重复最大负荷进行训练，包括卧推、平行深蹲、下拉和腿弯举练习。在干预前后，使用线性速度传感器获得了卧推和深蹲的个体力-速度曲线，并在干预期间测量了乳酸和机械性能。结果表明，两种方案后，卧推的力-速度曲线都有相似的变化（斜率没有变化，但力和速度轴截距的值更高）。对于深蹲，集群训练后斜率（P=0.001）和速度截距（P=0.002）有显著变化，但传统训练后没有变化。这些结果表明，组间配置可能会调节力-速度关系的变化，尤其是对于深蹲。
