| Outline of Final Research Achievements |
This study aimed to provide effective training for improving change of direction performance (CODp) of female athletes. For this purpose, we analyzed the development of CODp from junior-high-school age to adult and the correlation among CODp and body size, sprint speed, and muscular power. In addition, we investigated the relation between kinematic characteristics during COD maneuver and CODp. Consequently, CODp considerably improved from junior-high-school to high-school age. This improvement had only a weak correlation with body size, sprint speed, and muscular power, regardless of age category. Moreover, shorter contact time during deceleration and the stop phase correlates with a faster COD. Quick movement of the center of body mass (COM) toward Z axis (downward)/sec. during the deceleration phase increases the COD speed. Thus, we planned a training procedure to control COM, and this program effectively improved CODp of female athletes.
