Does Adolescent Awkwardness Existence ——A Comparative Study Of Motor Performance Among Adolescents Of Different Ages

As the second growth peak of an individual,the most obvious change during puberty is the rapid increase in height and the length of trunk and legs,but the muscle volume and strength cannot reach the year-on-year increase.The physiological changes in a certain extent can make teenagers to get the development of individual growth,but also may lead to the emergence of some bad posture even movement disorders,and the movement of the normal process and actions have influence,temporary movement performance decline,which appeared in the traditional sense of the "clumsy" puberty（Adolescent Awkwardness）phenomenon.At present,part of the research through the study of the test and analysis of some indicators has been found that the phenomenon of "clumsy" adolescence is may not be,but domestic youth movement performance for different ages and "awkward adolescence" phenomenon exists study is less,for the development of the youth movement performance and its influencing factors of system of empirical study is less,the lack of domestic hard study in this paper,the "clumsy" puberty this phenomenon.This paper USES the methods of literature material method,test method,using the Mr’s second edition version of Jane action proficiency test（BOT-2SF）assessment scale,action and action proficiency test of 302 different ages,different puberty and different gender youth a comparative study of the movement performance,in order to determine the domestic different ages youth movement performance is declining in the adolescent stage,whether there is "awkward adolescence" phenomenon,its gender performance if there is a difference.The main conclusions of the study are as follows:1.Through the BOT–2SF,different stages of adolescence adolescents,action performance tests show that the total score of different stages of puberty overall movement performance of teenagers and various specific movement performance scores are presented after a stage than the previous stage growth the tendency,not temporary movement performance difficulties,which does not exist "awkward adolescence" phenomena of the youth movement performance.2.The continuity of growth and development at various stages of adolescence and the social and psychological factors such as the adolescent’s experience and mental maturity may be the reason why there is no "awkward adolescence".3.The development speed of specific indicators of adolescent motor performance is different at various stages of adolescence,among which the early to middle adolescence is the period when all indicators of girls and most indicators of boys increase the fastest.4.There is no gender difference in the scores of specific action performance indicators of adolescents in the early stage of puberty,while there is gender difference in the scores of specific action performance indicators of adolescents in the middle and late stages of adolescence.Specifically,girls are higher than boys in fine motor accuracy and manual dexterity in mid-adolescence,and boys are higher than girls in upper limb coordination and strength.In late adolescence,girls are higher than boys in fine motor accuracy and manual dexterity,and boys are higher than girls in upper-limb coordination,speed and agility,and strength.5.There are gender differences in the growth rate of adolescent behavior at different stages of puberty.Specific performance in: in early adolescence to the intermediate stage,fine motor accuracy,fine motor integration and hand dexterity index,and middle to late adolescence stage upper limb coordination,power,one of the few indexes such as girls are growing faster than boys and dexterity is growing faster than equal,other indicators,whether at any stage during adolescence,boys are growing faster than the girl.
