The Effect Of Taekwondo Exercise Intervention To Primary School Students’ Physique Level

Research objectives: Using taekwondo exercise interventionexperiment study not only to observe the influence of primaryschool students’ physical quality, functional status body shape, andthe influence of mental health quality indicators, but also to explorethe role of taekwondo practice in improving primary schoolstudents. What’s more, it can provide theoretical basis andreference for people to choose the exercise project which canimprove primary school students physical.Research methods:1. Reviewing relevant literature tounderstand the physical status of primary school students atpresent stage in China and the situation which taekwondomovement carry out in primary and secondary schools, also tounderstand the research progress of this subject and the relatedresearch methods.2.Use the intervention of experiment study. InEight One Street primary school (Grade four) from Chang zhi, ShanxiProvince, randomly selected40male students,40female students,and then randomly divided into intervention group and control groupby sex. During the experiment, the control group only participate inphysical activities (physical education classes and extracurricular sports activities, etc.), while intervention group in addition togeneral sports activities, they increase taekwondo practiceintervention. The experimental intervention time is12weeks.Selects the Height, Weight, Thigh circumference, Calfcircumference, Step index, Lung volume, RHR, Sit and reach,Lateral front split, Standing long jump, Supine leg lift30times, Leglifts50times, Knee cocked30times,50-meters coming-and-goingrun8times, Standing on one foot with closed eyes and the qualityindex for the effect index of mental health.Experiment on theselected indicators respectively before and after the experimentmeasurement, using SPSS17.0to process and analyze the data, andthen statistical inspection between the two groups and statisticalinspection of each group.Research results:1. The physical aspects:(1) flexible quality:after the experiment, boys and girls from the intervention grouphave significantly increased in sit and reach and lateral front split (P<0.01),while the boy and the girl from the control group change verylittle (P>0.05).Compared two groups, we can see very significantdifference (P <0.01).(2) the power quality: after the experiment,boys and girls from the intervention group standing long jumpperformance has significantly improved (P <0.05),also the boy andthe girl from the control group have significantly increased (P <0.05),but the girls from the control group do not have significantdifference (P>0.05). Compared two groups, we can see the boy hasa significant difference (P <0.05),the girl has no significant change(P>0.05).(3) speed quality: after the experiment, boys and girlsfrom the intervention group significantly shortened the time when they do supine leg lift30times (P <0.05) while boys and girls fromthe control group do not have significant difference (P>0.05).Compared two groups of completion time there was nosignificant difference (P>0.05).The time of boys and girls from theintervention group complete leg lifts50times compared with theexperiment before there was no significant difference (P>0.05),boys and girls from the control group also have no significantdifference (P>0.05).After the experiment, the intervention groupcompared with the control group in the time of leg lifts50times,there was no significant difference (P>0.05).The time of boys ofintervention group complete knee cocked30times changed notobvious (P>0.05),the girls finish time compared with theexperiment before there are significant differences (P <0.01),andthe time of the boys and girls from the control group complete kneecocked30times do not have significant change (P>0.05).After theexperiment, the intervention group compared with the controlgroup, the time they complete knee cocked30times do not havesignificant difference (P>0.05).(4) the endurance quality: after theexperiment, the time of boys from the intervention group50-meterscoming-and-going run8times don’t have significant change (P>0.05), the girl’s scores increased significantly (P <0.05) and theboys and girls from the control group compared with the experimentbefore50-meters coming-and-going run8times don’t havesignificant change (P>0.05).After the experiment, the interventiongroup compared with the control group50-meters coming-and-goingrun8times do not have significant difference (P>0.05).(5)Sensitiveand balance quality: after the experiment, the time of boys from the intervention group standing on one foot with closed eyes obviouslylonger than the boys from the control group (P <0.05),while the girlsfrom both group standing on one foot with closed eyes don’t havesignificant change (P>0.05),the time of boys and girls from thecontrol group standing on one foot with closed eyes compared withthe experiment before don’t have significant difference (P>0.05).After the experiment, the time of the boys from theintervention group standing on one foot with closed eyes muchlonger than that of the boys from the control group, it hassignificant difference (P <0.01), and compared two groups of girls,the time of standing on one foot with closed eyes is not difference (P>0.05).2.Physical function: after the experiment, the step index andlung volume of boys and girls from the intervention group increasedsignificantly (P <0.01),the RHR of boys and girls from theintervention group did not change significantly (P>0.05),the stepindex, lung volume and RHR of boys and girls from the control groupdid not change significantly (P>0.05).After the experiment, theintervention group compared with the control group did not changesignificantly in each index (P>0.05).3.Body shape: after the experiment, the weight of boys and girlsfrom the intervention group was obviously lower (P <0.05),while theweight of boys and girls from control group increased a little but notobvious (P>0.05).Compared two groups, it have no significantdifference (P>0.05).the height of boys and girls from interventiongroup were significantly increased (P <0.05),while the height ofboys from the control group increased not obvious (P>0.05),the girls significantly increased (P <0.01),after the experiment,intervention group compared with control group, the height changehad no significant difference (P>0.05), thigh circumference andcalf circumference of boys and girls from intervention group andcontrol group compared with before the experiment don’t havesignificant change (P>0.05).After the experiment, interventiongroup compared with control group, the thigh circumference andcalf circumference don’t have significant difference (P>0.05).The quality of mental health: after experiment, boys and girlsfrom the intervention group mental health diathesis (MHRSP value):learning disorder(A),mood disorders (B),the character flaws(C),social adaptation obstacles (D),character flaw (E),badhabits(F),behavior disorders (G),seven scores were significantlydecreased (P <0.05), special obstacles (H) don’t have significantchange (P>0.05).boys and girls from the control group mentalhealth diathesis (MHRSP value): learning disorder (A) and so oneight score values don’t have significant difference (P>0.05), afterthe experiment, the intervention group compared with the controlgroup,it don’t have significant difference (P>0.05).Conclusion:(1)12weeks of taekwondo practice interventionpromote the primary school students’ physical flexibility, speed,strength, stamina, agility, balance, quality, the manifestation is thatboth boys and girls’ the speed of sit and reach, lateral front splitbecome faster, standing long jump improve, supine leg lift30timesfaster, the girls’ knee cocked30times faster;girls’50-meterscoming-and-going run8times faster; boys standing on one foot withclosed eyes can insist longer. it promote the function of cardiovascular system for primary school students. themanifestation is step index, lung volume increased significantly. butthe RHR don’t effect too much. In terms of body shape: it can loseweight, reduce the role of the incidence of obesity, but comparedwith control group, the effect on height, thigh circumference andcalf circumference, it don’t have significant difference. It promoteprimary school students mental health, making MHRSP valuedecreased obviously.(2) During the experiment, the control group join the physicaleducation, participate in physical activities also can conducive tothe physical quality, functional status, physical form and thedevelopment of mental health diathesis. The reason is that pupilsare in the growth development period, even if they don’t participatein any sports activities, the physical indicators will also have acertain degree of increase. But compared with the interventiongroup, the increase rate is relatively low, slower, which can furtherillustrate taekwondo practice has good effect to promote thedevelopment of primary school students physical fitness.
