The focus of this study was to determine if adding hang clean (HC) to a structured weight training program can make an improvement in vertical jump (VJ). High school student athletes (N=173), were randomly assigned to three groups that all performed the same secondary lifts. The control group (SQG) performed six sets of squat (SQ). Another group performed three sets of HC and three sets of SQ (CSG). The remaining group performed six sets of HC and no SQ (HCG). Pre- and post-assessments of VJ were recorded at the beginning and end of the six week study using a Vertec. The study determined a significant difference of average VJ improvement between both the CSG (1.48 inches) and HCG (1.05 inches) when compared to the SQG (.26 inches). There was also a significant difference between the CSG and HCG leading to the recommendation to implement HC equally with SQ to maximize VJ.
