A Research Note on Relationships Between the Vertical Jump and Standing Broad Jump in Law Enforcement Recruits: Implications for Lower-Body Power Testing

Lockie, RG, Moreno, MR, and Dawes, JJ. A research note on relationships between the vertical jump and standing broad jump in law enforcement recruits: implications for lower-body power testing. J Strength Cond Res 36(8): 2326–2329, 2022—Jump testing is often used to infer lower-body power in law enforcement recruits. The vertical jump (VJ) is most common, but can be equipment-intensive. The standing broad jump (SBJ) also provides a measure of lower-body power, requires less equipment, and could be practical for training staff with limited resources. There has been no analysis of the relationships between the VJ and SBJ in law enforcement recruits to ensure they measure similar qualities. This research note investigated the relationships between the VJ and SBJ in recruits from one agency. The sample included 71 men and 23 women who completed the VJ and SBJ before academy. Independent samples t-tests compared the sexes in both jump tests. Pearson's correlations calculated relationships between the VJ and SBJ variables (VJ height, height relative to body mass, peak power and power-to-body mass ratio calculated from VJ height; SBJ distance and distance relative to body mass) in all recruits combined, men, and women. Male recruits outperformed females in all absolute VJ and SBJ variables (p
