The Study Of National Rhythmic Gymnastics(Primary School) Motion Intensity And Energy Consumption Characteristics

Objective:The purpose of this study is to compare the changes of exercise intensity,energy consumption and heart rate during the national youth rhythmic gymnastic exercise to the radio waves the youth,and to analyze the changes of exercise intensity and energy consumption during the national rhythmic gymnastic exercises,Provide further theoretical basis for further development and promotion.Research Methods:40 primary school students were drawn,randomly divided into ethnic rhythm group and dancing youth group.Ethnic rhythmic gymnastics group practice rhythmic gymnastics for 5 minutes,3 times a week for 8 weeks;dancing youth group in the same time and frequency practice during the practice of radio gymnastics youth,for 8 weeks.The two indexes are collected.The first acquisition was during the third exercise of the first week and the second was during the third exercise of the eighth week.The two indicators collected telemetry jerk when the subjects in two groups quiet before the jump 3 minutes,during and after the jump operation to return to a quiet state of heart rate;test energy consumption before the jump 3 minutes,during jump and after the jump to return to a quiet state.Data were processed using SPSS Statistics 18.0 software,all data expressed as mean ± standard deviation(x ±s),one-way ANOVA(one-way ANOVA)was used to test the differences between groups,paired t test before and after the group,significant Levels were defined as P<0.05 and very significant levels as P<0.01.Using GraphPad Prism software to make plot.Results:The rhythms of rhythmic gymnastics of primary school students are generally consistent with those of rhythmic youth.The results of the first test showed that the rhythms of rhythmic gymnastic exercise and the youth boys were both lower than those of boys.The MET classification belonged to moderate intensity.The results of the second test of ethnic rhythmic gymnastics,dance youth girls sports intensity HR classification,MET classification were moderate intensity,ethnic rhythmic gymnastics,dancing youth boys sports intensity HR classification was low intensity,MET classification was moderate intensity.The first test of energy consumption of national rhythmic gymnastics 13.20 ± 4.27kcal,boys 13.71 ± 5.38kcal,ethnic rhythmic gymnastics energy consumption of girls 15.25 ± 3.57kcal,boys 15.52 ± 2.78kcal;the second test of national rhythmic gymnastics The energy consumption of girls 12.84 ±3.90kcal,boys 10.57 ± 6.94kcal,the energy consumption of national rhythmic gymnastics girls 14.69 ± 3.83kcal,boys 11.21 ± 4.49kcal.There was no significant difference in the energy expenditure of practicing national rhythmic gymnastic exercises and dancing youth in two tests.Exercise two exercise gymnastics when the trend of heart rate changes the same problem,exercise rhythmic gymnastics rhythm heart rate appeared first increased then decreased and then increased the trend of practice dancing youth heart rate was gradually increasing trend.Conclusion:By comparing the results of two national rhythmic gymnastic exercises,the intensity of exercise,the change of heart rate and the energy consumption of national rhythmic gymnastic exercises,the first section of rhythmic gymnastics can be slightly improved to be a better choice for practicing aerobics among the pupils.
