An Experimental Study On The Effect Of Table Tennis Exercise On The Cognitive Function Of 4th Grade Students In Elementary School

Objectives: By observing the changes of indicators such as memory,attention,executive ability,reaction time,brain-derived neurotrophic factor(BDNF),insulin-like growth factor-1(IGF-1),and vascular endothelial growth factor(VEGF)in 4th grade elementary school students by 16 weeks of table tennis exercise,and analyzing the changes of memory,attention,executive ability,reaction time caused by16 weeks of table tennis exercise and BDNF,IGF-1,VEGF and other indexes changes,to explore the effect of table tennis exercise on the cognitive function of 4th grade elementary school students,and to provide a scientific theoretical basis for the development of cognitive function of elementary school students by table tennis exercise.Methods: The 4th grade elementary school students were used as the experimental subjects and divided into experimental group(N=24)and control group(N=15).The experimental group was required to perform table tennis exercise for 16weeks(3 times per week,90 min per session)in addition to completing the school physical education curriculum,while the control group did not participate in other physical activities in principle in addition to completing the school physical education curriculum.In this experiment,the subjects’ cognitive episodic behavioral indicators(memory,attention,executive ability,reaction time)were measured using the alphabet without regular order,Schulte’s square,Flanker’s task,and HHTC100/FY’s selective reaction time tester before,at the end of 8 weeks,and on the day after the table tennis exercise experiment,respectively,while elbow venous blood was collected in the morning of the day,and the serum was separated and stored at low temperature,to be measured BDNF,IGF-1,VEGF and other indices were collected in the morning.SPSS 27.0 was used for statistical analysis of the data,Graph Pad Prism was used for charting and graphical analysis,repeated measures ANOVA was used to analyze the differences and interactions between groups,and Pearson was used for correlation analysis,with r indicating the correlation coefficient and P < 0.01 or P <0.05 indicating a significant difference.The result are as follows: 1.Compared with the pre-experimental period,the cognitive episodic behavioral performance of the experimental group and the control group gradually improved at the end of 8 weekends and in the late experimental period,in which the control group had no significant improvement in all cognitive behavioral performance(attention,inhibitory control,and reaction time)except for memory(P < 0.05),and the experimental group had significant improvement in all cognitive episodic behavioral performance(P < 0.05),and in the Later in the experiment,the cognitive behavioral performance of the experimental group was better than that of the control group,and there was a significant difference between the two groups in all cognitive episodic behavioral test results(P < 0.05).2.Compared with the pre-experimental period,the concentration levels of BDNF,IGF-1 and VEGF in the experimental group and the control group gradually increased at the end of the 8th week and at the later stage of the experiment,but the concentration levels of BDNF,IGF-1 and VEGF in the control group did not increase significantly(P > 0.05),and the experimental group showed a significant increase in the concentration levels of all indicators(P < 0.05),and the BDNF,IGF-1 and VEGF concentration levels were higher than those of the control group,and the two groups reached significant differences in the concentration levels of BDNF and IGF-1(P <0.05).3.Pearson correlation analysis showed that the values of change in BDNF concentration were significantly positively correlated with the values of change in memory score(P < 0.01),significantly negatively correlated with the values of change in time spent on Schulte’s square(P < 0.01),significantly negatively correlated with the values of change in time spent on Flanker task response(P < 0.01),and significantly negatively correlated with the values of change in time spent on response(P < The change in IGF-1 concentration was significantly positively correlated with the change in memory score(P < 0.01),significantly negatively correlated with the change in Schulte’s square time(P < 0.01),not correlated with the change in Flanker task reaction time(P = 0.10 > 0.05),and significantly negatively correlated with the change in reaction time(P < 0.01),respectively.concentration change values were significantly positively correlated with the change values of memory score(P < 0.01),significantly negatively correlated with the change values of Schulte’s square time use(P < 0.01),significantly negatively correlated with the change values of Flanker task reaction time(P < 0.05),and significantly negatively correlated with the change values of reaction time(P < 0.01),respectively.Conclusions: 1.16 weeks of moderate-intensity table tennis exercise could effectively improve cognitive-related episodic behavioral performance such as memory,attention,inhibitory control and reaction time.2.16 weeks of moderate-intensity table tennis exercise was effective in increasing BDNF,IGF-1,and VEGF concentrations,with the best promotion of BDNF and IGF-1 concentrations and the second best promotion of VEGF.3.In the 16-week table tennis exercise intervention,table tennis exercise increased the concentration levels of cognitive episodic behavioral performance and cognitive neurobiological indicators with increasing practice time in 4th grade students.4.The increase in memory,attention,inhibitory control,and reaction-time behavioral performance in elementary 4th graders due to 16 weeks of moderate intensity table tennis exercise was associated with elevated levels of BDNF,IGF-1,and VEGF.
