Subjects were given real-time feedback for every repetition during the training sessions. EXP performed jump squat training 3 times per week using loads that allowed all repetitions to be performed with ≥90% of maximum average power output (13 sessions with 4 sets of 8 repetitions and 13 sessions with 8 sets of 4 repetitions). Tests were completed pre-, mid- and post-training. Sixty eight subjects (~21 years, ~180 cm, ~75 kg) were divided into experimental (EXP n = 36) and control (CON, n = 32) groups. The purpose of the study was to determine the effects of 8 weeks of jump squat training on isometric half squat maximal force production (Fmax) and rate of force development over 100ms (RFD 100), countermovement jump (CMJ) and squat jump (SJ) height, and 50 m sprint time in moderately trained men.
