COMPLEX TRAINING: AN EVALUATION OF POTENTIATION BETWEEN A 3RM BACK SQUAT AND A SQUAT JUMP

Abstract

Complex training (CT) is increasingly popular among strength and conditioning coaches. CT hypothesises that a near maximal muscle contraction will enhance the explosive capabilities of the muscle given the exercises are biomechanically similar (Docherty et al., 2004). Previous CT research has focused on intra-complex potentiation between near maximum exercises and a similar stretch-shortening cycle exercise. The effect of CT on starting strength (SS) has yet to be explored. The optimal rest interval between the loaded exercise and the explosive exercise is somewhat unclear. Comyns et al. (2006) investigated potentiation between a 5RM back squat (BS) and a counter movement jump. Results varied between individuals. The purpose of this study was to determine if a heavy loaded exercise (3RM BS) results in a performance increase on a SS exercise (squat jump).
