| Purpose:Post-activation potentiation(PAP)is a physiological response and is considered as a muscle strength enhancer.This physiological event may be caused by the conditioned training before the main activity,resulting in an increase in the speed of nerve impulse transmission to the muscle,an increase in the number of motor units recruited,and an improvement in the interaction mechanism between myofilament and sarcomere.In order to verify the promotion of PAP effect on badminton players’ sports ability,this study designed two kinds of PAP activation schemes to explore the performance of badminton players after activation,and provided theoretical and experimental basis for verifying the influence of PAP effect on badminton players’ sports performance.method:Select 30 badminton special college students from Tianjin Institute of Physical Education,and randomly divide them into three groups: experimental group A,experimental group B and control group.After the warm-up activities of all the personnel,the subjects were tested for throwing medicine ball in front of them,fast four-point movement speed in the whole field,hitting score test and badminton spike muscle i ENG test.After the test,the experimental group A adopted activation scheme A,the experimental group B adopted activation scheme B,the control group rested,and the relevant data of the subjects were tested at 3,6,9,12 and 15 minutes after activation,The paired sample t-test was used for the relevant data before and after activation,and the one-way ANOVA was used for the data between different groups to analyze the enhancement effect of PAP effect on the sports ability of badminton players.result:The paired sample t-test showed that compared with the pre-test,the test results of 9 min and 12 min after the activation of the front throwing ball muscle in experimental group A were significantly different(p<0.01);There was a significant difference in the test results 9 minutes after the activation of the four-point fast moving muscle in the whole field(p<0.01);There was a significant difference between the results of 6 min test and 9 min test after muscle activation in the score of fixed ball stroke(p<0.01);There was a significant difference in the results of the swing test of the triceps brachii muscle 3 min and 6 min after the activation of i EMG in group A(p<0.05);There were significant differences in the test results of pectoralis major muscle i EMG 3 min,6 min and 9 min after activation(p<0.05,p<0.01);There was significant difference in the test results of deltoid muscle i EMG 3 min after activation(p<0.05);There were significant differences between the test results of the rectus femoris muscle i EMG 3 min,6 min and 9 min after activation(p<0.05,p<0.01);The test results of semitendinosus i EMG 3 min after activation were significantly different(p<0.05).There were significant differences in the test results of gastrocnemius muscle i EMG 3 min,6 min and 9 min after activation(p<0.05,p<0.01).Through paired sample t-test,it was found that compared with the pre-test,there was a significant difference between the test results of 3 min and 6 min after the activation of the front throwing ball muscle in experimental group B(p<0.05);There was a significant difference between the test results at 3 min and the test results at 9min after the activation of the four-point fast moving muscle in the whole field(p<0.05,p<0.01);There were significant differences in the results of the test at 3 min,6 min and 9 min after the activation of the muscle(p<0.05,p<0.01);There was a significant difference in the test results of triceps brachii i EMG 3 min after activation in group B(p<0.05);There was significant difference between the test results of pectoralis major muscle i EMG 3 min and 6 min after activation(p<0.05,p<0.01);The test results of deltoid i EMG 6 min after activation showed significant difference(p<0.05);There was significant difference between the test results of the rectus femoris muscle i EMG 3 min and 6 min after activation(p<0.05,p<0.01);There was significant difference between the test results of gastrocnemius muscle i EMG 3 min and 6 min after activation(p<0.05,p<0.01).After univariate analysis of three groups of data,it was found that the i EMG of pectoralis major muscle in experimental group A was significantly different from that in control group 3 min after activation(p<0.01);The i EMG of pectoralis major muscle in group B was significantly different from that in control group 3 min after activation(p<0.05).The i EMG of the rectus femoris in group A was significantly different from that in group B 3 min after activation(p<0.05);The i EMG of the rectus femoris in group A was significantly different from that in the control group at 3 and 6min after activation(p<0.05).Conclusion:Compared to ordinary warm-ups,the effects of different intensities of PAP on the improvement of badminton players’ forward throwing distance and muscle i EMG are different,while the effects of high intensity PAP activation schemes on the improvement of subjects’ forward throwing distance and muscle i EMG are better.Compared to ordinary warm-ups,different intensity PAP effects have different effects on improving badminton players’ fast moving speed and fixed path practice scores,while low intensity PAP activation schemes have better effects on both.Research has confirmed that high intensity activation has a better stimulation effect on muscle strength and i EMG,but it does not enhance other athletic performance of athletes as much as low intensity activation,which may be related to fatigue recovery after muscle exertion.Relevant conclusions need further research to confirm. |
