| 摘 要： | 目的：探究激活后增强效应（PAP）间歇时间对下蹲跳高度影响。方法：检索PubMed等数据库，查找相关随机对照试验，检索时间从建库至2017年11月30日。按纳入与排除标准筛选文献、提取数据和评价纳入文献研究方法质量后，采用Review Manager 5.3软件进行Meta分析。结果：共纳入15篇文献286名受试者。Meta分析结果显示：间歇时间为0~3 minMD=-1.46，95% CI（-2.15，-0.78），P<0.000 1]，实验组优于对照组；间歇时间为4~7 minMD=1.90，95% CI（0.81，2.99），P=0.000 6]和8~12 minMD=1.46，95% CI（0.78，2.15），P<0.000 1]，对照组优于实验组；间歇时间为13 min以上MD=-0.45，95% CI（-2.26，1.36），P=0.62]，对照组与实验组间的差异无统计学意义。敏感性分析提示：改变研究质量差异、纳入标准、统计模型以及效应量的选择等，发现合并结果改变不明显，且受异质性影响的可能较小。结论：诱导方式为杠铃深蹲，诱导强度在85%~93% 1RM之间，重复次数为5~10次，可诱导产生PAP。间歇时间为0~3 min，可以明显提高受试者下蹲跳高度，间歇时间为4~7 min和8~12 min时下蹲跳高度未能显著增加，间歇时间为13min以上时，仍需更多高质量随机对照试验进一步研究证实。在制定诱导PAP方案时，还需考虑诱导对象的年龄与性别、训练经历和力量水平对PAP的影响。

| Abstract: | The purpose of this study was to explore the effect of the postactivation potentiation intermittent time on squat jump height. PubMed and other databases were electronically searched to collect the randomized controlled trials(RCTs) from the date of their establishment to November 30th, 2017. According to the inclusion and exclusion criteria, literature was screened, data were extracted, and the methodological quality of included studies was also assessed. Meta-analysis was performed using Review Manager 5.3 software. It was seen that fifteen RCTs were included involving 286 cases. Meta-analysis showed that the results of RCTs depended on intermittent time, the experimental group was better than the control group in 0~3min(SMD=-1.46,95%CI -2.15 to -0.78, P<0.000 1). The control group was better than the experimental group in 4~7min(SMD=1.90, 95%CI 0.81 to 2.99, P=0.000 6) and 8~12min(SMD=1.46,95%CI -0.78 to -2.15, P<0.000 1). There was no significant difference between the control group and the experimental group above 13min(SMD=-0.45,95%CI -2.26 to 1.36, P=0.62). The results of sensitivity analysis showed that there was a little change in the result of the merger after changing the quality of research, inclusion criteria, statistical models, and the selection of effects, the impact according to heterogenicity was fairly low. It could be concluded that the induced pattern was barbell squat, the induced intensity was between 85%~93%1RM, and the repetition is 5~10 times, which could induce PAP. The height of the squat jumps varied from intermittent times, there was an obviously increase in 0~3min, no significant increase in 4~7min and 8~12min, while there needed further verification by high quality, large scale and double blinded RCTs above 13min. When formulating the PAP plan, the influence of the age and gender, training experience and strength level on the PAP should also be considered. |
