Abstract

Jump squats are a simple exercise that can be used to train lower body power. Unlike many other methods of power training, jump squats do not require any specialized equipment (platforms, bumper plates, etc.). Jump squats can be used when other forms of power training are not available or are not allowed. In order to most efficiently train power, the intensity must balance force and velocity. The purpose of this study was to find the intensity that yields the peak power output of a jump squat. 12 participants (9 males, 3 female) participated in the study. Each participant completed a parallel back squat one repetition maximum (1RM) test. The results of the test were used to assign the loads for the jump squats. On a separate day, each participant completed a series of jump squat trials starting at 0% of the back squat 1RM and working up to 50% in 10% increments. A one-way repeated measures ANOVA showed that power output was significantly higher at the 30% and 40% intensities than the 0%, 10%, and 20% intensities (p<0.05). Power output was significantly higher at the 50% intensity than the 0% and 10% intensities (p<0.05). It was concluded that power output is maximized with jump squats when an intensity of 30%-40% of parallel back squat 1RM is used.
