| Motor development is a complicated process,and it crosses in our whole life cycle.To carry out the study of children's movement development,on the one hand,it helps us to understand and control the growth period of the child's health and the actual condition of sports level,on the other hand,the corresponding research results can also be a good guide of the school sports teaching practice about the choice of teaching contents and teaching methods."Hop" as one of the basic skills of the human body,the quality of movement affects the strength and speed of human body,physical coordination and physical balance ability.The study of analysis children`s hop,not only can it find change regularity of the human basic movement skills,but also the study has important effects on school sports and lifelong sports.This paper analysis children's basic motor skills development characteristics by literature method,observation method and interview method.Picking out 180 students of six grade from Hebei province Tangshan city Luannan county Shangpozi primary school,and in order to analysis the hop,it adopts test method,video analysis,and mathematical statistics methods.the video uses video studio software,and the research result reveals the part movement technology characteristics,the whole movement development characteristics and different gender children of different ages 7 to 12 years old children`s hop.The conclusion is as follows:1.7-12 years old children hop action main link characteristics:(1)Kick off stage : Most of the head movements remain upright;The trunk is primarily a slightly tilted forward;Both arms lift up to the head,shoulder position,gradual transition to coordinated swing.The supporting leg is gradually moving towards full extension.(2)Empty stage: The head is mostly kept upright;The two arms are gradually formed on both sides of the body to coordinate the oscillating technique;The supporting leg has a slight bend in the knee joint;The swing leg is on the side of the leg supporting the leg,the wiggle foot lags behind supporting the leg is the main characteristic.(3)Landing buffer phase: keep your head upright;The degree of tilting in the torso is very different2.7-12 years old children hop integral action characteristics:(1)different age children's upper extremity movement performance: by the two arms of irregular fluctuation gradually to the coordination of two arms in development;(2)the upper limb movement performance: different gender children at the age of 7 men and women embrace mutually to exert oneself to do this action has not been achieved,at the age of eight girls first appeared opposite force ACTS.(3)lower limbs in children of different age movement performance: the swinging leg folded in front of the support leg side or basic not moving gradually to the swinging leg actively,support legs fully stretching in development;(4)different gender children lower limb movement performance: at the age of 7 men and women embrace no hop senior movement performance,swinging leg at the age of eight began to significantly stretching movements,9 years old began to appear completely stretching,swinging leg support leg coordination of oscillating movement performance.3.Children aged 7-12 continuous hop performance characteristics: from the point of finished time,the time required is on the decline,the speed has enhanced,;From the point of failure times,it is generally a downward trend,It shows strength,speed,endurance,sensitivity and balance. |
