The aim of this study was to compare the number of maximal intended velocity (MIV) barbell squat repetitions performed at different loads (40%, 60%, and 80% 1RM) to a 10% velocity loss threshold between physical education students (n = 26) with endurance- (E-group) and resistance-training (R-group) backgrounds. Mixed-model ANOVA results indicated an interaction between loads and training groups (p < 0.05, η² = 0.162) in number of repetitions performed. In the E-group, the number of repetitions decreased as load magnitude increased (10, 6 and 5 at 40%, 60% and 80% 1RM, respectfully). Differences between groups were observed only at the 40% 1RM load, where the E-group performed ~50% more repetitions compared to the R-group (10 vs. 5; p < 0.05). Training history influences the number of MIV squat repetitions at lower loads. Thus, monitoring repetition velocity at the individual level is essential for optimizing strength and power training adaptations.
