Postactivation Potentiation Following Acute Bouts of Plyometric versus Heavy-Resistance Exercise in Collegiate Soccer Players

Abstract

Postactivation potentiation is referred to as an acute and temporary enhancement of muscle performance resulting from previous muscle contraction. The purpose of this study was to compare the acute effect of plyometric exercise (PLY) and heavy-resistance exercise (RES) on the blood lactate level (BLa) and physical performance. Fourteen male collegiate soccer players were randomized to perform either RES or PLY first and then crossed over to perform the opposite intervention. PLY consisted of 40 jumps, whereas RES comprised ten single repetitions at 90% of one repetition maximum. BLa and physical performance (countermovement jump height and 20-m sprint) were measured before and at 1 and 10 min following the exercise. No significant difference was observed in the BLa for both exercises (PLY and RES). Relative to baseline, countermovement jump (CMJ) height was significantly better for the PLY group after 1 min (P = 0.004) and after 10 min (P = 0.001) compared to that of the RES group. The 20-m sprint time was significantly better for PLY at 10 min (P = 0.003) compared to that of RES. The present study concluded that, compared to RES, PLY causes greater potentiation, which leads to improved physical performance. This trial is registered with NCT03150277.

Effects of Plyometric and Whole-body Vibration on Physical Performance in Collegiate Basketball Players: A Crossover Randomized Trial

“…Similarly, Requena et al, 40 reported an increase in CMJ height of 3.08 cm at a 5-minute rest interval after 25 plyometric repetitions. Additionally, Sharma et al, 41 reported decreased CMJ height by 4.8% immediately after plyometric exercise, however, after 10 min of recovery the CMJ height was increased by 13%. The contrary, Esformes et al, 42 reported no additional bene t of plyometric exercise in increasing the performance of CMJ height.…”

“…The speculated mechanism for this potentiation was enhanced activation of the musculature and an increased recruitment of type 2 motor units. 49 Sharma et al, 41 reported increased sprint time by 2.4% immediately after plyometrics, however, the sprint time was reduced by 8.9% after 10-min of recovery. This improvement in sprint performance could be because of optimal motor neuron excitability and recruitment of fast twitch bres.…”

Effects of plyometric and whole-body vibration on physical performance in collegiate basketball players: a crossover randomized trial

“…Once a participant fulfilled the eligibility criteria and agreed to participate, an independent assessor drew the next folder of the file to assign the group. Participants were randomized to first receive either WBV or plyometric training and after 48 h of the wash-out period 35 , they were crossed over to receive the opposite intervention. Participants in group one (n = 12) first did WBV followed by plyometric training, while the other group (n = 12) first did plyometric training followed by WBV (Fig.…”

The Use of Different Modes of Post-Activation Potentiation (PAP) for Enhancing Speed of the Slide-Step in Basketball Players

“…In training practice, the potentiation can be achieved by the execution of biomechanically similar conditioning activity (CA) at maximal or near-maximal intensities prior to the subsequent athletic task (e.g., heavy-load back squat before countermovement jump) [17]. Over the past years, there has been a large amount of scientific research related to the use of various CA exercises to enhance the performance of movements such as lifting of free weights [18][19][20], performing ballistic and plyometric exercises [21,22], and maximal isometric voluntary contractions [23]. Although that assisted [24,25] and resisted sprint modalities [26][27][28] are the two commonly used filed methods of improving acceleration and velocity of sprint, the available data regarding their use as CA to induce potentiation of subsequent performance is scarce.…”
