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 10repetition 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 transducerbeforeandaftertheintervention,alongwithlactateand mechanicalperformanceduringtheintervention.Resultsshowedin bench press similar changes of the force-velocity profile after both protocols (no shift of the slope and higher force and velocity axis interceptvalues).Forthesquat,significantchangesintheslope(P= 0.001) and the velocity intercept (P = 0.002) towards a velocity profile were observed after cluster but not after traditional training.
