American football players vary in body composition across player positions. Components of body composition may affect jumping performance. The purpose of this study was to investigate the relationships between lean body mass, fat mass, total body mass, vertical jump (VJ) height, VJ reactive strength, and VJ kinetic asymmetry. 39 players had their body composition assessed using a BOD POD and VJ kinetics via a force plate. Pearson correlation coefficients quantified relationships between the variables, allpha =.05. VJ height and reactive strength were highly and very highly negatively associated with lean body mass, fat mass, and total body mass, p
