The Study Of The Influence Of Special Class Exercises On The Physical Fitness Of Elementary School Students In Dalian

Research purposeLiang qichao once said that "the youth is strong",the youth is the future and hope of the motherland.However,in recent years,the decline of teenagers has become an urgent problem to be solved.Special class exercises is on the basis of the traditional class exercises the plait,jump rope as a "national students physical health standard" test indicators will measure project,"football into campus" as countries develop and support the policy,this paper mainly studies figure jump rope exercise,football exercise the class exercises two characteristics influence on elementary school students physical fitness,to compare the physique between primary school students who participated in characteristic recess exercises and primary school students attending radio gymnastics for one year,in order to provide theoretical basis for improving pupils' physique.Research objects and methodsThis article selects 180 second grade students in dalian as the research object,with an average age of 8,each group of 60 people(males = 30 people,female = 30 people),as figure jump rope exercise,soccer exercise group,broadcast Gymnastics group.The figure jump rope exercise is selected from Shahekou District fushun street primary school,football exercises selected from Shahekou District jinxiu primary school,broadcast gymnastics is selected from Shahekou District wenyuan primary school.Test students body shape index(height,weight,body mass index),body function index(lung capacity,quiet heart rate),physical quality index(50 m running,1 minute sit-ups in succession,crook proneness,grip,standing long jump,quadrant jump,close my eyes on one foot).Using the team's heart rate table to monitor the changes of heart rate of middle school students,and to evaluate the intensity of exercise intensity.The subjects were given two physical fitness tests before and after the break.SPSS21.0 data package,this paper analyses the statistics,descriptive statistics,statistical data of the test process,data with average ± standard deviation,according to difference between groups by comparing the mean of the single factor analysis of variance,P< 0.05 showed statistically significant difference.Results(1)Before the experiment,the body shape indexes of the three groups were compared with each other.There was no significant difference in height,weight and BMI(P > 0.05).After the experimentt,the body morphological indexes of the three groups were compared,and there was no significant difference in height,weight and BMI(P > 0.05).(2)Before the experiment,there was no significant difference in the body function indexes between the three groups,and there was no significant difference in vital capacity and quiet heart rate(P > 0.05).After the experiment,there was no significant difference between the three groups in their physical function indexes,and there was no significant difference in vital capacity and quiet heart rate(P > 0.05).(3)There was no significant difference in physical fitness between the three groups before the experiment(P > 0.05).After the experiment,compared with the radio gymnastic group,there was a significant difference in the grip strength between the two groups of boys(P < 0.01),and the figure skipping group was better than the radio gymnastic group.Standing long jump,50 m,synchronized rope skipping exercise group is better than radio gymnastics group.Compared to the two groups of girls,there was a significant difference in grip strength(P < 0.01).There were significant differences between the two indexes of standing long jump and 50 m running(P < 0.05).The figure jump rope gymnastics group was better than the radio gymnastic group.Compared with the radio gymnastic group,there was a significant difference between the two groups of boys in the standing and quadrant jump(P < 0.01),and the football team was better than the radio gymnastic group.There was a significant difference in standing long jump index(P < 0.05),and the football gymnastics group was better than the radio gymnastics group.The comparison between two groups of girls in football gymnastics and radio gymnastics was that there were significant differences between the quadrant jump and the closed eye single foot standing index(P < 0.01),and the football gymnastics group was better than the radio gymnastic group.There is a significant difference in standing long jump index(P < 0.05),and the football gymnastics group is better than the radio gymnastics group.Compared with pattern jumping and football gymnastics,the two groups of boys had significant differences in the standing index of closed eye and foot(P <0.05),and the football gymnastics group was better than the figure skipping group.The comparison results of the two groups of girls were that there was a very significant difference between the grip strength and the quadrant jump(P < 0.01),and the figure jump rope group of the grip strength index was obviously superior to the football team.The quadrant jump index is better than the figure skipping exercise group.(4)The average heart rate of students do rope skipping exercises and football exercises process compared no significant difference(P > 0.05),the average heart rate of students do rope skipping exercises and gymnastics in the process of broadcasting are very significant difference(P < 0.01),the average heart rate of students do exercises and gymnastics in football in comparison there was significant difference(P < 0.01).Conclusions(1)The characteristics of one year's special class break exercises are compared with that of radio gymnastics.(2)A year's synchronized rope skipping exercise can improve the upper limbs strength,lower limbs strength and speed quality of pupils.(3)A year's soccer exercise and radio gymnastics can improve pupils' basic physical strength such as strength,sensitivity and balance.(4)A year of synchronized skipping and football exercises compared with one year's broadcast gymnastics have more emphasis on the physical quality of primary school students,so the effect of pattern jumping and football exercises on the physique of primary school students is better.(5)The selected pattern jumping rope and football operation are of moderate intensity exercise for primary school students,and the heart rate is in the effective value range of fitness load(60%MHR~80%MHR),which conforms to the HR training standard of fitness.radio gymnastics is a small intensity exercise for primary school students,and the heart rate is not in the effective value range of fitness load(60%MHR~80%MHR).
