Abstract |
INTRODUCTION The purpose of this study was to investigate the influence of basic ballet practice on walking pattern and type of ground reaction force for elementary students. METHOD 16weeks ballet program was conducted with practice group and non practice group, consisting with 3 low elementary students for each group. Differences between pre and post test for step length and step width, change of body center position, upper body angle, impulse and maximum impact force were examined by using 3 dimension cinematography and ground reaction force. Mean and standard deviation were calculated and two-way ANOVA with repeated measure were conducted using PASW. RESULT First, basic ballet practice influenced to increase stability for children's step and muscle training showed a significant effect. Second, basic ballet practice resulted unstable step with left and right movement by influencing left and right of the center of gravity, and left and right of upper body angle from the practice. Also, there was a inter-relation among step width, left and right of the center of gravity, and left and right of upper body angle. Third, basic ballet practice helped stable step because of its effect on ground reaction force peak. CONCLUSION Basic ballet practice for children increased stability of step and control ground reaction force peak for step. In turn, basic ballet practice has much change of left and right which results on shakily walking and may has negative effect on step. |
