The purpose of this study was to investigate the effects of nine months of plyometric training on the muscular strength and power of the lower extremity in athletic girls(aged 16.5±0.5 year). 16 subjects were divided into the control group and the plyometric group. The control group maintained their usual activities and the plyometic group participated in the program that was designed to load the lower extremities. The strength by isokenetic dynamometry and power by Wingate were assessed at baseline and nine months. ANCOVA revealed significant differences between groups for the strength and the power. The trend observed in the strength and the power between groups suggest that plymetric training continued over a longer period of time may increase knee extensor strength.
