In order to select the index for evaluating the static balance,establish the digital standard evaluating and give service to identification of the static balance in technology difficulty programs in sports.The authors adopted the balance force plate and computer as well as interrelated software produced by Hefei institute of intelligent machine,Chinese Academy Sciences,and tested untrained 140 boys aged 8,and got every subject thirty-six indexes.Then with the methods of Hierarchical Cluster Analysis and Factor Analysis,7 indexes were selected as factors for evaluating the static balance,and the evaluating system was established based on the evaluating system,evaluating structure was also established.After getting the definitive score of the static balance of all subjects by using the formula of single index and evaluating structure,the five-grade standard to evaluate the static balance of boys age 8 was established.
