Objective: This investigation involved examining whether Rest-Redistribution Set (RR) and Traditional-Set (TS) resistance priming (RP) protocols could induce a Delayed Potentiation Effect (DPE). Additionally, it was analyzed whether the RR protocol demonstrated significant advantages over the TS protocol in various performance parameters across different testing time points following the RP. Method: Twenty-four male collegiate Physical Education majors participated in this study, each completing two resistance protocols involving the back squat exercise: (1) a RR protocol incorporating a 30-s intra-set rest and a 200-s inter-set rest, and (2) a TS protocol without intra-set rest and with a 240-s inter-set rest. Both protocols comprised four sets of five repetitions performed at 85 % of one-repetition maximum (1RM). Performance outcomes, including countermovement jump (CMJ), sprint time, Y-balance test scores, change of direction (COD) ability, and agility, were evaluated at three time points: baseline (Pre), 6 h post-exercise (Post-6h), and 24 h post-exercise (Post-24h). Data were analyzed using a two-way repeated-measures analysis of variance (ANOVA) with factors for protocol (RR vs. TS) and time (Pre, Post-6h, Post-24h). When significant main effects or interaction effects were identified, Bonferroni-adjusted post hoc pairwise comparisons were conducted. Results: < 0.001). Conclusion: Both the RR and TS protocols induced DPE at the Post-6h mark. The RR protocol improved CMJ...
