The Initial Establishment Of The Evaluation System For Juvenile Static Balance Ability (Age Between 14-18)

The essay is set in the harmonious society,national fitness programme and the mass sports,and it is based on the balanced ability test technology and the computer software programming.It is necessary to establish a set of evaluation system and necessary software to analyze the balanced ability of human body,which also take advantages of mathematical statistics,biomechanics of sports,graph and iconography,information fusion to solve a series of key issues from theory and applications,such as the test information extraction,analysis,fusion of many parameters,and the inosculation and adhocery of multiple target component. The investigation of Juvenile Period of Balance Evaluation System will make the evaluation process of human balance ability more convenient and fast.The system may help to complete the ,increase the test method of disease control and prevention of juvenile,help couch analyze and evaluate athlete's balanced ability conditions,and make the training and the competition more scientific,digitization and theorization.We can also use it in many fields such as gymnastics,shooting,martial arts,figure skating,and other sports items of having especial requirement for balance,so as to make contributions to the Chinese sports in personnel reserve.The basic information and balance parameters can be obtained through test.Testing equipment contains height and weight measuring instrument,Chinese Academy of Sciences,Hefei Institute of Intelligent balance production load Units and Computer and the corresponding software.Test objects are No.25^th junior high school students of Shijiazhuang City and High school students of Subsidiary of Hebei Normal University,it Contains 155 males and 174 females.There are 6 different postures in each test,that is,standing quietly on the force plate with double feet and eye opening(DFDOE);with double feet and eye closing (DFDCE);with left foot and eye opening(LFDOE);with left foot and eye closing (LFDCE);with right foot and eye opening(RFDOE);with left foot and eye closing (RFDCE).There are 96 indicators in total,each posture contains 16 indicators.Among these indicators,8 of them are comprehensive balance ability indexes(Env Area,Lng,Lng·t^-1,Lng·A^-1,V,Wavvol,Deg,Eng),4 of them are left and right direction balance ability indexes,and 4 of them are forward and backward direction balanced ability indexes.All of the factor analysis,exploratory data analysis and deviate score methods have been used as mathematical statistics to help to establish the evaluation system of juvenile period of balance ability.The computer technology(VC++6.0,VC++2005) also have been introduced to assisting the set up of software foundation of human body static balance ability evaluation system,by extract the information,analyze and process,module set up and multiple parameters objectives integrating.The factor analysis can be used to analyze parameter and extract common factors,make sure the contribution rate of each common factor,and make the contribution rate as a weight score to set up score formula.The deviation score method divides the balanced ability into upper,middle upper,middle,middle lower and lower levels, and creates the evaluation system to two aspects,one is male and the other one is female.Use the VC++6.0 and VC2005 technology to edit the following five modules:the module of basic software information,module of newly promoted evaluation indicators,the show module of curve and parameters,the module of evaluation of youth's balanced ability,the module of data Storage and Excel-compatible.Eventually,structures the software system of balanced ability evaluation.The measurement indexes may divide into the comprehensive balance ability index,the direction balance ability index and around the direction balanced ability index.Based on the design of six different postures and three different kinds of balance ability indexes,the essay is trying to make the evaluation criteria more specific and more directive.In addition to evaluation of balance ability overall and refinement indicators,this system divided evaluation into comprehensive evaluation,the direction balance ability evaluation and around the direction balanced ability evaluation.Because of the different superiority legs,bringing appraisal error of the single foot to stand the posture(RFDOE,RFDCE,LFDOE,LFDCE),so that we can divide evaluation of balance ability into four different kinds DFDOE,DFDCE, single foot and eye opening(LFDOE) and with single foot and eye closing(OFDCE). Juvenile Period of Static Balance Ability Evaluation System including five modules:the module of Basic information,the module of evaluation index,the show module of curve and parameters,the module of evaluation of youth's balanced ability and the module of data Storage and Excel-compatible.Compared with the similar software,the function,the data storage and the information feedback which expected or pursued by this evaluation system is more comprehensive,formidable,convenient,and immediate.
