Abstract

International Journal of Exercise Science 17(4): 154-171, 2024. The purpose of this study was to evaluate the effectiveness of implementing task-specific, post-activation performance enhancement (PAPE) strategies, to acutely improve Army Combat Fitness Test (ACFT) performance. Nineteen ROTC cadets completed two ACFTs, separated by 72 hours. Approximately half (n = 10) completed the traditional “Preparation Drill” as their warm-up prior to the first session and added PAPE warm-up strategies as part of their second session. The other group (n = 9) completed the treatments in the opposite order to facilitate a repeated-measures, crossover design. The participants’ composite ACFT score was used as the primary outcome measure of interest to explore mean difference in a two-way (Time x Treatment), repeated measures ANOVA. There was no interaction [F(1,8) = 0.075, p = 0.79] nor main effect of treatment [F(1,8) = 0.084, p = 0.78]. However, there was a main effect of Time [F(1,8) = 58.87, p < 0.001, d = 0.25] (mean ACFT score ± SD: Session 1 = 527 ± 43, Session 2 = 537 ± 39). The results of this study did not support the use of additional PAPE strategies to improve ACFT performance. However, there was a practice effect when the test was completed twice, separated by 72 hours in those with ACFT experience. The effect of Time was present for ACFT cumulative score, as well as event-level differences in three out of six events. Further research should implement familiarization sessions to minimize a practice effect from influencing results.
