Abstract:
OBJECTIVE:To test the static balance function of boys aged from 6 to 8 years and then to establish a system of evaluating the static balance function.METHODS:A total of 388 boys aged from 6 to 8 years were randomly selected from 16 kindergartens of 8 counties(cities)in 4regions of Hebei Province.The inclusive cdteria were as follows:no systematic training of sports,no myopia,normal body shape and no obvious obesity.The balance force-measuring plates made by Hefei Institute of Intelligent of Chinese Academy of Sciences,computer and the supporting software were adopted.The subjects received an indoor test of 6 testing postures,namely,standing on two feet with eyes open(and closed),standing on left leg with eyes open(and closed),standing on right leg with eyes open(and closed).Six indexes relating to balance abilities including the mean of X direction,the mean of Y direction,R value,track length per unit time and track location variance of the envelop area.RESULTS:The original screening of all indexes showed that 6 kinds of postures reduced to 4 and that indexes reduced from 36 to 24.The second screening with cluster analysis which was conducted to the 4 kinds of postures showed that 24 indexes reduced to 17 when selecting typical indexes from each cluster.The third screening with factor analysis showed that 7 out of the 17 indexes were remained.Seven representative indexes corresponding to these 7 factors were concluded and considered as the comprehensive evaluation indexes of the static balance.The comprehensive static balance evaluation index systems for 6-year-old.7-year-old and 8-year-old boys were established respectively.CONCLUSION:Three systems for evaluating the static balance function of the boys aged from 6 to 8 years are established successfully based on 7 indexes.The evaluation of static balance function should be based on the comprehensive evaluation of multiple indexes.The evaluation indexes for 6-year-old,7-year-old and 8-year-old boys are identical in number,but different in content.Accordingly,a specific evaluation index system should be established for them separately.
