| Research Abstract |
The purpose of this study was to clarify the kinematical characteristics of the high and low skilled female students on some selected moter skills. The techniques of hurdling on obstacle race, successive movements on liorizoiital bar and kicking of soccer ball were chosen. The performances of respective skills were analyzed kinematically by means of einematography. The main results were as follows;
1. Hurdling on obstacle race Eight of variables on hurdling techniques were analyzed such as initial velocity of take-off, take-off length, landing length, rate of take-off length, maximal height of center of gravity, take-off angle, angle of trunk lean during hurdling, and angle of trunk lean at landing. As the results, the low skilled students were shown to be shorter on take-off length and slower on velocity of take-off than the highly skilled students.
2. Movements on horizontal bar The successive movements were pullovers, forward rolls and forward roll landing. Variables were swing-up angle of foot, awing-up velocity of foot, backward lean angle of head and changes of knee angle during pullovers, the velocity of trunk rotation, angular velocity of trunk rotation. angle of trunk lean, and changes of knee angle during forward rolls and locus of tip toe during forward roll landing. As the results, the low skilled students were shown to be inferior on rotating the trunk around the horizontal bar smoothly to the highly skilled students.
3. Kicking of soccer ball Variables analyzed were initial velocity of kicked ball, velocity of kicking foot, angles of hip and knee at ball inpact, angle of projection of kicked ball and horizontal moving distance of body segments. As the results, the low skilled students were shown to be inferior on utilizing the body segments to kick the ball efficiently to highly skilled students.
