Post-activation potentiation following different modes of exercise, R-31239, Revision 1Post-activation potentiation following exercise 3 ABSTRACTThe performance characteristics of skeletal muscle are transient in nature and have been shown to be significantly affected by its contractile history, where the phenomenon of acute enhancement is termed post-activation potentiation (PAP). Acute enhancement of dynamic activity has been observed when preceded by resistance exercises, however little information exists for plyometric activity as a conditioning stimulus. In addition, no study has examined PAP effects on more than one subsequent performance trial. The purpose of the present study was to determine whether countermovement jump (CMJ) performance could be enhanced if preceded by heavy resistance exercise or by dynamic plyometric activity over three trials.Thirteen anaerobically trained male subjects (mean ± SD: age, 22 ± 3 years; height, 182.4 ± 4.3 cm; body mass, 82.7 ± 9.2 kg) performed in a counterbalanced order 3 half squats using a 3 repetition maximum loading (SQUAT), a set of 24 contacts of lower body plyometric exercises (PLYO), or a control of no activity (REST) 5 min prior to each CMJ. Three sets of each treatment and CMJ were performed in total and maximal displacement (dmax), peak power (Ppeak) and peak vertical force (Fpeak) were recorded, while rate of force development (RFD) and relative force (F / body mass) were calculated for every trial. No significant differences were revealed for any of the other variables, but greater displacement was found for SQUAT compared to REST or PLYO, while no differences were revealed for any of the conditions for the repeated trials. Although heavy resistance-induced PAP seems to enhance jump height compared to REST or PLYO in repeated CMJ performance, it has no additional benef...

Specific warm-up exercise is the best for vertical countermovement jump in young volleyball players

“…In the present study, VCMJ performance increased after resistance exercise, similar to the results of other investigations that demonstrated a positive change in jumping performance after highintensity squat exercises 13,15 . Although the leg press is a multi-joint exercise (similar to jumping), biomechanically the two have some differences (e.g., the ballistic nature of jumping, and the different body positions) that could influence the post-activation potentiation response 16 .…”

Efeito da potencialização pós-ativação no Atletismo: uma revisão sistemática

“…Most studies found in the current review suggest the presence of post-activation potentiation in different athletics events 16,34,35,36,37,38,39 . This may be associated with neuromuscular and molecular changes induced by strength and power activities such as: 1) better recruitment of motor units, especially type-IIx motor units, which have a higher contraction velocity and capacity to generate tension; 2) increased availability of Ca ++ for contraction and 3) increased phosphorylation of light myosin chains, facilitating the interaction of contractile filaments 1,3 .…”

“…Karampatsos et al found greater distance in hammer throw one minute after three countermovement jumps (Pre = 62.92 ± 4.43 m, Post 64.42 ± 5.13 m, p = 0.047) and one minute after 20-m sprint (Pre = 64.87 ± 3.90 m, post = 65.30 ± 4.02 m, p = 0.013) in six experienced male hammer throwers. However, Esformes et al 38 analyzed the effects of 24 plyometric jumps with alternating legs on the height of counter movement jump (CMJ) in well-trained adult jumpers and sprinters and found no difference in CMJ after five minutes of interval between conditioning activities (p> 0.05). According to the author, the duration of jumps used in the study was too long, which required less intensity for its accomplishment.…”

“…Esformes et al 38 analyzed the effects of a series of 3RMs of squats on the height of counter movement jumps (CMJ) in well-trained jumpers. The interval between conditioning activity and main activity was five minutes.…”

“…However, it can also enhance subsequent force generation and improve strength and power performance (3,8,11,16,21,23), a phenomenon termed post-activation potentiation (PAP). PAP has been attributed to three possible mechanisms; regulatory light chains phosphorylation, increased recruitment of motor units, and muscle fibre pennation angle change (for review see 22).…”
