Study On The Development Characteristics And Promotion Strategies Of Fundamental Motor Skills For Children Aged 7-10

Research purposes: Starting from the definition of fundamental motor skills,the fundamental motor skills include locomotor skills,object-control skills,stability skills.Through the construction of the stability skill evaluation scale,and on the basis of the TGMD-2 scale,the overall development evaluation model of children's fundamental motor skills is constructed to comprehensively evaluate the development of children's fundamental motor skills.In addition,from the perspective of human movement development,the general characteristics of the development of children's fundamental movement skills at the stage of 7 to 10 years are summarized according to the movement development sequence theory.At the same time,the age and gender differences of the fundamental movement skills development level and mastery of children aged 7-10 were tested,and the relationship between the development of fundamental movement skills and body mass index,physical fitness and other indicators of children aged 7-10 years was discussed.Finally,based on the fundamental movement skills promotion strategy and the development status of children's fundamental movement skills in China,a program for promoting fundamental movement skills development for children was formulated to explore the effects of fundamental movement skills development promotion programs on children's fundamental movement skills.Research methods:(1)In the compilation of the stability skills assessment scale for children aged 7 to 10 years old and the construction of the overall assessment scale for fundamental movement skills development,the investigation is mainly through the Kendall's coefficient of concordance,Average,Coefficient of Variation and Cumulative percentage the degree of recommendation,the degree of divergence of recommendation and the concentration of recommendation of experts on differentindicators;the retest reliability,inter-rater and intra-rater reliability of the Pearson related check scale;Cronbach ? coefficient is used to test the internal consistency of the scale The Extreme analysis is used for the analysis of project differentiation;the evaluation of the content validity of the scale mainly uses the evaluation team to evaluate the validity of each indicator,including the item-level content validity index(ICVI)and the scale-level Content Validity Index(SCVI);Exploratory factor analysis and confirmatory factor analysis are mainly used for the structural validity test of the scale.(2)In the current situation of 7-10 year old children's fundamental movement skills development,single-factor analysis of variance is mainly used to examine the age difference of children's fundamental movement skills development;independent-sample T test is used to examine the gender differences of children's fundamental movement skills development.(3)Pearson correlation was used to investigate the relationship between the development of fundamental movement skills and BMI of children aged 7 to 10 years;single-factor analysis of variance was used to investigate the differences in the development of fundamental movement skills among children with different body mass index levels.(4)Pearson correlation and Multiple stepwise regression are used to simultaneously explore the relationship between the development of fundamental movement skills and physical fitness of children aged 7 to 10,and the relationship between the two is explained from different angles.(5)In the study of children's fundamental movement skills promotion interventions,the difference test of cardinal data mainly uses the independent-sample T test,and Repeated measurement analysis of variance mainly analyzes the time point factors(pre-test,post-test,follow-up test)and group Test the difference between different levels of other factors(control group,experimental group).Analysis conclusion:(1)The stability skills can be used as an independent dimension of the holistic measurement model for the development of children's fundamental motor skills.It mainly includes four test indicators: log roll,rock,balance beam,and landing buffer.(2)The general characteristics of the development of fundamental motor skills in children ages of 7 and 10 : the coordination of children is poor and the movement patterns is unstable;imbalanced development of left and right limb movements,performance of dominant side movements is higher than non-dominant side;the balance ability and posture control ability is low,the movement is not smooth;the sensory integration and the hand-eye coordination is poor.(3)There are age and gender differences in the development level and mastery of fundamental motor skills among aged 7 to 10 years in children.As the age increases,the development level and mastery of fundamental motor skills increase non-linearly.The development and mastery of locomotor skills and stability skills in girls are better than boys,and the development and mastery of object-control skills in boy is better than girls.(4)There is a significant correlation between the development of fundamental motor skills of 7 to 10-year-old children and BMI.There is a significant negative correlation between locomotor skills and stability skills and BMI.There is no significant relationship between object-control skills and BMI.There are differences in the relationship between age and gender.As the age increases,the relationship between fundamental motor skills and BMI becomes more significant,and the development of fundamental motor skills in boys has a significant correlation with BMI.(5)Different BMI levels have different effects on the development of fundamental motor skills in children.Obesity has a significant impact on the development of fundamental motor skills in children.There is no significantdifference in the effects of underweight,healthy weight and overweight on children's fundamental motor skills development.Obesity is a threshold that affects the development of children's fundamental motor skills.(6)There is a very significant positive correlation between the development of children's fundamental motor skills and total physical fitness scores.Among them,the correlation between locomotor skills and stability skills and the total physical fitness score is medium,and the correlation between object-control skills and total physical fitness score is low.(7)The fundamental motor skills promotion program should be supported by a multidisciplinary theoretical knowledge system,combined with the development status of children's motor skills,setting specific,systematic and operable action development goals,focusing on the content of motor education framework,teaching equipment,teaching methods,exercises Methods,evaluation systems and other multi-dimensional teaching strategies are used reasonably.(8)The fundamental motor skills promotion program can effectively promote the development of fundamental motor skills in children and improve their mastery of fundamental motor skills.The development of fundamental motor skills in children does not develop with age,but requires certain learning,practice,and enhanced exercises to develop.
