The jump squat is one of the exercises most frequently used to improve lower body power production, which influences sports performance. However, traditional determination specific workload at production maximized (i.e., optimum load) time-consuming and requires one-repetition maximum tests. Therefore, aim this study was verify whether elite athletes from different would produce mean propulsive values a narrow range velocities, resulting in similar heights. One hundred nine several individual/team sport disciplines underwent repetitions maximal velocity with progressive loads, starting 40% their mass increments 10% determine individual zone. Results indicated that regardless discipline, athletes' achieved close 1.0 m.s(-1) (1.01 ± 0.07 m.s(-1)) height 20 cm (20.47 1.42 cm). Data were narrowly scattered around these values. load can be determined simply by means or training/testing settings, allowing it implemented quickly strength/power training.
