摘　　要：探讨了最大自主等长收缩(MVIC)运动对大学生男子短跑运动员激活后增强效应(Post-Acti?vation Potentiation,PAP)的影响.研究招募40名大学生男子短跑运动员进行对比实验,通过对实验组进行3组的5秒MVICs(5 MVICs)运动训练,对照组进行3组的50米快速热身训练,记录训练后实验组与对照组采用45度倒蹬机的运动表现,记录两组运动员的腿部功率,以分析实验组与对照组激活后增强效应(PAP)的异同.研究表明,热身后第1分钟,5 MVICs运动和普通热身后,腿部力量和功率峰值均低于前测平均值;第5分钟后,实验组的后测功率显著高于前测平均值,力量与前测平均值无差别,出现了一定的激活后增强效应,而对照组后测力量与前测平均值无显著性差异,但后测功率显著高于前测平均值,出现了一定的激活后增强效应;第10分钟,实验组腿部功率和力量依然高于前测平均值,而对照组腿部力量和功率低于前测平均值,对照组并未诱发激活后增强效应.This paper discusses the effect of MVIC on post-activation Potentiation(PAP)of male sprinters in college students.Study recruited 40 male sprinters college students’experiment,through the study of the three groups of experimental group of 5 seconds MVICs in sports training,control group 3 group of 50 meters rapid warm-up exercises,the experimental group and control group after training record USES 45 degrees of pedal machine movement performance,record the leg power of the two groups of athletes,with the analysis of the experimental group and control group after activation enhanced the similarities and differences(PAP).The study showed that the peak strength and power of the legs were lower than the premeasured mean one minute after the warm-up,after 5 MVICs exercise and normal warm-up.After 5 minutes,the post-measured power of the experimental group was significantly higher than the average value of the pre-measured power,and there was no difference between the power and the average value of the pre-measured power,showing a certain post-activated enhancement effect.However,there was no significant difference between the post-measured power and the average value of the pre-measured power in the control group,but the post-measured power was significantly higher than the average value of the pre-measured power,showing a certain post-activated enhancement effect.At the 10th minute,the power and strength of the legs of the ex?perimental group were still higher than the pretest mean,while the power of the legs and strength of the con?trol group were lower than the pretest mean,and the control group did not induce the enhancement effect af?ter activation.
