Abstract :The aim of this study was to investigate the acute effects of eccentric contraction performed at different angular velocities (60°/s and 150°/s) on jump performance and to comparatively evaluate the contribution of eccentric loading at different velocities to the post activation performance enhancement (PAPE) effect. The study was completed in three sessions with 8 male participants. In the first session, anthropometric measurements, dominant leg determination, vertical jump test performance for the control condition and Familirization for eccentric contraction were performed. The next sessions were randomized at 48-hour intervals. In the second session, participants performed a single set of 5 repetitions (rep) maximal eccentric contractions at an angular velocity of 60°/s and after a 7-minute transition phase, vertical jump tests were performed. In the third session, participants performed a single set of 5 rep. maximal eccentric contractions at an angular velocity of 150°/s and after a 7-minute transition phase, vertical jump tests were performed. The results showed that two different angular velocities had no statistically significant effect on jumping performance (p>0.05). However, when compared with the control condition, 150°/s (+2.24 cm) has a higher delta value than 60°/s (+0.71 cm). As a result, especially eccentric contractions applied at higher angular velocity showed an increases in jump performance, indicating that angular velocity may be an important factor in the emergence of the PAPE effect ( Cohen d: 0.56).
