PRE and POST values are mean ± SD. Changes are POST − PRE means with 95% confidence intervals; the paired sample size is shown in each change cell. F and p values test whether PRE-to-POST changes differed among PBT, RIR, and VBT. Pairwise comparisons are reported in Table S5. Jump height was calculated using the impulse–momentum method; power and propulsive impulse were normalized to body mass. Abbreviations: PBT, percentage-based training; RIR, repetitions in reserve; VBT, velocity-based training; SJ, squat jump.
