Abstract: This investigation aimed to examine horizontal displacement and the ground reaction forces (GRF) attained in the standing long jump (SLJ) with varying squat depths and projection angles, and to see the relationships between squat strength, sprinting ability, and SLJ. Thirteen recreationally active performed a one repetition maximum back squat (1RM), a 40 yard sprint with five and 10 yard splits, and 18 SLJs. Subjects randomly performed three jumps at each of the six types of jumps: self-selected angle (SSA), lower angle (LA), higher angle (HA), self-selected depth (SSD), deeper depth (DD), and shallow depth (SD). A significant negative correlation was observed between SLJ and five and 10 yard sprints, and a moderate correlation was observed between SLJ and 40 yard sprints. A non-significant correlation was seen with the 1RM back squat relative to body mass and SLJ performance and all sprints. Vertical impulse (VI) generated during DD jumps was significantly greater than SSD and LD; however, SD jumps produced a non-significant greater distance than DD and SSD. Resultant impulse and resultant velocity were significantly greater in the HA condition compared to LA and SSA. A moderate, non-significant correlation was observed between VI and distance jumped when all jumps were considered.
