... Effect of external wrist weights on maximal countermovement vertical jump height in Loughborough University Sports Technology students. Abstract The aim of this study was to investigate the effect of external wrist weights on maximal countermovement vertical jump height. Data was collected from a group of eight Loughborough University students, who each performed three sets of jumps on a Kistler Quattro Jump platform with a variety of wrist weights. Though there were individual differences between subjects in the results, generally higher jumps were achieved when using external wrist weights, leading us to the conclusion that external weights on the wrists enhance performance, even if this is not the case when weights are attached to different body landmarks. Introduction Vertical jumping is a simple plyometric activity common to many different sports and tasks such as vertical jumps, hops, and/or bounding movements are often used to increase explosiveness and strength of the lower extremities (Ebben, 2005).
