The purpose of the present study was to classify standing posture of the upper grade elementary school children in the second sexual stage into five types according to Kendall's method, and to clarify factors affecting those postures by using seven muscle strength or flexibility tests. A total of 196 children (104 boys, 92 girls) were analyzed. Only 22% of children were a good posture even if the ideal and military postures were combined, whereas a bad posture, i.e., kyphosis-lordosis, flat-back and sway-back postures, accounted for 78%. The deviation of the body's center of gravity was significantly shorter in the good pasture than in the bad posture. When principal component analysis was applied to the data for seven muscular strength or flexibility tests, military posture had high overall evaluation of muscular strength and flexibility and kyphosis-lordosis posture was lower, whereas ideal posture was mainly held by muscular strength and flexibility of lower body and flat-back posture was mainly held by those of upper body. These findings suggest that it is necessary to improve muscle strength and flexibility in order to improve the bad standing posture of upper grade elementary school children.
