Countermovement jump (CMJ) height and Peak Power Output (PPO) were measured at 3, 6, 9, 12, 15, and 18 minutes post-activation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A significant condition \u00d7 time interaction was observed for CMJ height (p = 0.039), which was primarily driven by the divergent time-course trends between conditions in the early (3-6\u00a0min) and late (12-18\u00a0min) recovery phases.\n                      <jats:italic>Post-hoc<\/jats:italic>\n                      pairwise comparisons did not reach statistical significance (p &amp;gt; 0.05), while effect size analysis (HBS and MEB vs. Control at each time point) indicated practical improvements. The MEB protocol induced a rapid potentiation response, demonstrating moderate effect sizes in CMJ height and PPO as early as 3 minutes post-activation. In contrast, the HBS protocol exhibited delayed potentiation, with improvements appearing only after 9 minutes, likely due to residual fatigue.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Multi-dimensional elastic resistance is a time-efficient alternative for inducing Post-activation Performance Enhancement (PAPE), offering a rapid onset of practical potentiation (within 3\u00a0min) based on effect size analysis. These findings suggest MEB is particularly suitable for pre-competition warm-ups where recovery time is severely constrained.<\/jats:p>\n
