Özet
Drop jump is widely used in training sessions, aiming for chronic effects on long jump performance. However, the acute effect of drop jump on long jump performance through its use as a Conditioning Activity (CA) has not been explored. The objective of this study was to verify the Post-activation Performance Enhancement (PAPE) responses induced by successive Drop Jumps (DJ) on competitive long jump performance. Eleven male jumpers (19.0 +/- 2.0 years; 178.0 +/- 9.0 cm; 73.1 +/- 8.9 kg; and personal record 5.78 +/- 0.44 m) volunteered for participation. The athletes performed 5 drop jumps 2 min (1 ' 45-2 ' 15 min) before the second, and fourth attempt during official competition of state level, the attempts without the use of CA were considered controls. The performance of the second (5.63 +/- 0.43 m), third (5.65 +/- 0.46, g = 0.24) and fourth (5.71 +/- 0.34 m) jumps performed after activation were higher than the first (5.54 +/- 0.45 m) in the control condition, p = 0.02, and p = 0.01 respectively. Differences were also found in the take-off vertical velocity of the jump between the fourth (1.55 +/- 0.21) and the first jump (1.30 +/- 0.40), p = 0.006. Jump performance showed positive correlation with approach velocity, r = 0.731, vertical take-off velocity, r = 0.412, and take-off duration, r = 0.508. The mean performance in jumping post-activation (5.67 +/- 0.38 m) was higher than that without the use of previous CA (5.59 +/- 0.44 m), p = 0.02, g = 0.19. The use of DJs as a CA prior to the long jump promotes improvements in the performance of the jump, which can be explained by the increase in the take-off vertical velocity in the athletes.
