Research On Optimizing Model Of Basic Physical Fitness From The Perspective Of Coordination Ability

INTRODUCTION:The coordination ability is the comprehensive performance ability,which is the cooperative work of various qualities and occupies a dominant position in the various qualities.To date,the research on the internal relationship of the whole quality including coordination ability is lacking.OBJECTIVES:To explore the internal relationship between children's coordination ability and strength,speed,endurance,flexibility and agility quality.METHODS:This study involved 550 children aged between 10-12 years old.In this study,six indicators representing children's physical fitness were selected and tested.This paper analyzes the relationship between basic physical quality and coordination ability,and constructs the optimization model of basic physical quality under the guidance of coordination ability.CONCLUSIONS:(1)The average body mass index of children aged 10-12 in Suzhou city is in the normal range.The average level of speed,strength,flexibility,sensitivity and coordination ability of children with different genders was significantly different.The average level of strength,speed,endurance,sensitivity and coordination ability of children with different ages is significantly different.(2)According to the correlation analysis,The speed ability and coordination ability of boys and 12-year-old children are remarkably closely related;the strength ability and coordination ability of girls,children aged 10 and 11 are remarkably closely related;the flexibility ability of boys and 12-year-old children are not significantly related to coordination ability.(3)According to the regression analysis,the coordination ability of boys and girls,children aged 10 and 11 mainly depends on strength quality,and that of children aged 12 mainly depends on speed quality.Secondly,the coordination ability of boys and girls and 10-year-old children depends on speed quality,the coordination ability of 12-year-old children depends on strength quality,and the coordination ability of 11-year-old children depends on flexibility quality.(4)According to the path model,The endurance quality of children aged 10-12 years has the greatest influence on the coordination ability,among which the direct influence is less,mainly through strength,speed and other qualities indirectly affect the coordination ability.PROPOSE:(1)Coordination ability directly affects children's mastery of future motor skills,and basic physical quality is one of the factors affecting coordination ability,so it is an effective way to improve children's basic physical quality by improving their coordination ability.Many qualities of 10-12 year old children are in the period of rapid development,at this time their coordination ability and basic physical quality especially need the attention of schools,society and parents.(2)The results show that the speed quality and coordination ability of boys and 12-year-olds are the most closely related,while the strength quality and coordination ability of girls,10-11-year-olds are the most closely related.Therefore,for children aged 10-12 to improve the coordination ability,boys and children aged 12 can pay attention to the development of speed quality,girls,10 and 11 years old children pay attention to the development of strength quality,so as to achieve a variety of effects.(3)For physical trainers of children aged 10-12 years,more attention should be paid to improving the strength quality of boys and girls,the strength quality of children aged 10 and 11 years,and the speed quality of children aged 12 years in practice.Secondly,it is necessary to improve the speed quality of boys and girls and children of 10 years old,the strength quality of children of 12 years old and the flexibility quality of children of 11 years old.These differences in size and sequence largely determine the level of children's coordination.(4)It is found that the coordination ability level of 10-12-year-old children is mainly affected by endurance quality,followed by speed and strength quality,while speed and strength quality are also mainly affected by endurance quality.Therefore,the physical training of 10-12-year-old children can pay attention to the development of endurance quality when developing speed and strength quality,and more exercise endurance quality based sports exercises,such as swimming,timed obstacle running,chase running,etc.It can not only improve the development speed and strength quality,but also indirectly develop the coordination ability.
