The purpose of this study was to determine short-term effect of complex training with inclusion of postactivation potentiation (PAP) on average power output (Pmax) and countermovement jump (CMJ) in competitive athletes. Sixteen athletes (age: 21.3±3.3 years, height: 178.9 ± 8.6 cm, weight: 74.8±9.9 kg) were pair-matched and randomly assigned into intervention (INT) (n=8), and control group (CON) (n=8). Over a training period of a 6-weeks with training frequency 2 days per week, the subjects underwent pre-, mid(after 3 weeks), and post-testing (after 6 weeks) in CMJ and Pmax. Before the start of each training session EXP performed PAP protocol which consisted of 3 sets and 4 repetitions of half-squat jump exercise with individualized loads on (Pmax), whereas CON continued their normal complex training without the inclusion of PAP. Both groups significantly improved performance after 6 weeks of training. Novel findings of this study have shown that the INT which has been regularly performing PAP protocol before each training session achieved greater gains in Pmax (16.5 % vs. 4.9 %, p<0.01, from preto mid-training) and CMJ (15.4 % vs. 8.3 %, p<0.05, from preto post-training) compared to the CON. In conclusion, it seems that performing potentiating protocols before complex training sessions can potentially enhance motor performance in competitive athletes.

半蹲跳跃增强协议对功率输出和反向运动跳跃性能的短期影响

这项研究的目的是确定复杂训练的短期影响，其中包括后激活电位（PAP）对竞技运动员的平均功率输出（Pmax）和反运动跳跃（CMJ）的影响。对16名运动员（年龄：21.3±3.3岁，身高：178.9±8.6 cm，体重：74.8±9.9 kg）进行配对，并随机分为干预（INT）（n = 8）和对照组（CON）（n = 8）。经过为期6周的训练，每周训练2天，对受试者进行CMJ和Pmax的前，中（3周后）和后测试（6周后）。在每次训练开始之前，EXP进行了PAP协议，该协议包括3组和4次重复的半蹲跳高运动，并在（Pmax）上施加个性化负荷，而CON则继续进行其常规的复杂训练而未包括PAP。训练6周后，两组均显着改善了运动表现。这项研究的新发现表明，在每次训练之前一直定期执行PAP协议的INT在训练前至中期的Pmax（16.5％vs. 4.9％，p <0.01，p <0.01）和CMJ（15.4％vs.与CON相比，从训练前到训练后8.3％，p <0.05）。总而言之，似乎在进行复杂的训练之前执行增强协议可以潜在地提高竞技运动员的运动表现。（从训练前到训练后）与CON进行比较。总而言之，似乎在进行复杂的训练之前执行增强协议可以潜在地提高竞技运动员的运动表现。（从训练前到训练后）与CON进行比较。总而言之，似乎在进行复杂的训练之前执行增强协议可以潜在地提高竞技运动员的运动表现。
