Effects Of Taekwondo Body Composition Of Primary School Students

Esearch purposes: the Taekwondo exercise intervention experiment,effects of exercise on body composition related to pupils through the experimental observation of Taekwondo,explore the positive role of Taekwondo to improve body composition of students,provide reference and theoretical basis for the growth of primary school physical exercise and physical health project selection of Taekwondo.The research object of the third grade students in Hebei District the crescent River Primary School in Tianjin city were randomly selected from the height of 40 people are basically the same as the experimental group and control group 20,the experimental group is the exercise intervention group of Taekwondo,the experimental time is 16 weeks,every week 2 hours class,each class.The weight,height,body mass index(BMI)percentage of body fat,muscle index,content percentage as effect indicators.The selected indicators were measured before and after the experiment,and the data.Were analyzed by SPSS17.0 and EXCEL2003,significant differences between the two groups before and after the experiment data(p value),and statistical analysis was performed by the group and between groups of the experimental results.Methods: After 16 weeks of exercise intervention on Taekwondo pupils body weight and height,body mass index(BMI),has a certain guiding the healthy development of body fat and muscle content to promote the role of specific performance is as follows: Pupils' body weight,body mass index(BMI)and the body fat percentage had no significant difference in the experiment compared with before the obvious change,the body fat content significantly,body fat percentage decreased,with significant difference,with reduced fat and reduced to a series of diseases caused by obesity on children's physical morbidity after the experiment;percentage of height and muscle content than before the experiment is improved,but the change small,no significant difference.During the experiment,the experimental group in the control group and the intervention of Taekwondo together in the school physical education and school sports activities,will also be on children's body function component has the influence of weight and height and other indexes of the control group are increased,the growth rate of experimental group was significantly higher than the control group,and the most obvious effect of body fat percentage in the experiment were decreased compared with the control group,body fat percentage growth,to a good control effect on Pupils' body fat growth rate,so that has a good role in promoting the practice to improve the development of Taekwondo on body composition of pupils.
