Abstract: The purpose of the following study was first to identify an optimal warm-up to maximise countermovement jump (CMJ) performance, and second to investigate whether a conditioning activity (CA) of half-squats could potentiate CMJ performance above that of the optimal warm-up.Sixteen resistance trained males were recruited for the study.Participants performed six different warm-up volumes over six sessions.Warm-ups consisted of submaximal running, dynamic stretching and practice CMJs.After the warmup, participants rested for four minutes before performing three CMJs on a force platform.The warm-up which resulted in the best CMJ relative peak power (RPP) was considered to be that individual's optimal warm-up.Participants attended another testing session where they performed their optimum warm-up followed by a pre-CMJ test.Participants then performed a CA of four half-squats with a 5RM load followed by post-CMJ tests after fourand eight-minutes recovery.No CMJ variable displayed significant improvements at either four or eight minutes recovery after the CA when compared to the pre-test.However, when everyone's optimum recovery period was considered, CMJ height significantly improved by 5.2% (p = 0.009) when compared with pre-CMJ performance.If the optimum recovery period is considered, a half-squat CA can further improve CMJ height above that of a general warm-up alone.
