| description | The purpose of the present study was to investigate effect of post-activation performance enhancement (PAPE) induced by the eccentric half-squat exercise on vertical jump performance in male jumpers. The jumping height, peak power, and work were measured and evaluated in twenty male jumpers (age: 21.2 ± 1.7 years, height: 191.1 ± 3.3 cm, body mass: 81.56 ± 7.3 kg) who participated in the national championship last year. Participants performed five eccentric half-squats at 85% of their one-repetition maximum (1 RM), with a knee angle below 90°, followed by immediate and 2 min delayed jump assessments using the Squat Jump (SJ) and Countermovement Jump (CMJ) tests. Results showed that this specific PAPE protocol did not significantly improve jump performance for the SJ (Height: ES = 0.613, <i>p</i> = 0.462, Work: ES = 0.124, <i>p</i> = 0.231, Power: ES = 0.382, <i>p</i> = 0.125) or CMJ (Height: ES = 0.523, <i>p</i> = 0.368, Work ecc: ES = 0.133, <i>p</i> = 0.505 (only main effect time <i>p</i> < 0.05), Work con: ES = 0.114, <i>p</i> = 0.101, Power ecc: ES = 0.134, <i>p</i> = 0.177, Power con: ES = 0.182, <i>p</i> = 0.195, Leg stiffness: ES = 0.095, <i>p</i> = 0.358) tests. Factors such as stimulus specificity, rest intervals, muscle length, and the balance between potentiation and fatigue may explain these results. This study highlights the complexity of PAPE responses and suggests that a single set of eccentric squats with a short rest may not improve jump performance in male jumpers. Further research is required to optimize the interplay between conditioning stimuli and rest periods to maximize PAPE effects in athletic performance enhancement. |
