The purpose of this study was to investigate coordination structure of infront kick in women soccer as a function of skill level. To succeed this purpose, four girls' high school students who had never experienced soccer before were selected as novices, and four girls' high school students who had played soccer for over three years as experts in this lab. To recognize the change of coordination structure according to practice, novices had practiced infront kick in soccer for two weeks. consequently they were taken films of kicking motion three times -before practice, after one week practice, after two weeks practice. However, experts were taken once. The experimental instruments for this study consisted of a video camera, reference frame. LED and APAS for digitizing. Angle to angle diagrams and phase plan portraits for qualitative analysis of coordination structure were gotten with LabVIEW 6i. The conclusions are as follow: firstly, novices' coordination structure had been changed since practice. Secondly, there were significantly different between coordination structures of experts and pre-practice novices. Lastly, there were similar between coordination structures of experts and post practice novices.
