Aquatic training has become more prevalent as a means of training power, and provides unique features such as buoyancy and inflicting less stress on the body than traditional land based training. Purpose: The purpose of this study was to assess absolute and relative peak propulsive and mean power in loaded countermovement jumps (CMJ) performed on land and in water in Division I soccer players and gymnasts. Methods: Twenty-four Utah State University soccer players (N=12) and gymnasts (N=12) performed randomized countermovement jumps in eight conditions (Land BW, BW+10%, BW+20%, BW+30%; Chest-height water BW, BW+10%, BW+20%, BW+30%). Peak power (PP), relative peak power (rPP), mean power (MP), and relative mean power (rMP) were examined for all jumping conditions. A 2 (sport team) by 2 (environment) by 2 (load) repeated measures ANOVA was used to evaluate main effects and interactions. Results: PP, rPP, MP, and rMP were not significantly different for increased loads within the same environment. When compared to jumps performed on land, all four variables were significantly higher for water conditions (p
