The purpose of the present study was to verify the impact of posture education by observing changes in standing posture before and after posture educational intervention in K junior high school and clarifying the influence of the intervention on center-of-gravityfluctuation and muscular strength. A total of 58 students (28 boys and 30 girls) wereanalyzed. Before the intervention, a good posture (i.e., the ideal and military postures) and a bad posture (i.e., kyphosis-lordosis, flat-back and sway-back postures) were observed in 14 (24%) and 44 (76%) students, respectively. After the intervention, however, the number of students with a good posture increased to 36 (62%) students and the number of those with abad posture was halved to 22 (38%). Furthermore, the deviation of the bodyʼs center of gravity shortened, muscle strength of the hip adductor increased, and the number of students who have completed standing tests (both dominant and non-dominant legs) increased.These findings indicate that intervention of posture education dramatically improvedstanding posture and increased muscular strength related to hip joint movement, suggesting that posture education of K junior high school was effective
