This is to make a comparable analysis on jump-shoot motions of handball players in the long-shoot zone.
For this analysis, the writer has referred to a 16mm motion picutre showing complete performance of the Korean, Japanese and Chinese players who participated in the Asia Regional Qualification Games for the 7th world Ladies’ Indoor Handball Championship.
The subjectors were selected each 2maximum scoring players among who does the shooting players among who doer the shooting with the ball grasped in one hand (Group-A) and not grasped (Group-B).
The result of this study are summarized as follows:
1. As for the angle of take-off leg in jump motion. Group-A proved superior to Group-B.
2. Concerning the flying time (from take-off till release). Group-A stayed longer than Group-B.
3. Group-A rendered longer horizontal transfer distance then Group-B.
4. In ball velocity. Group-A was 18.73m/sec. Group-B 16.04m/sec to 16.64m/sec wher-by group-A was faster.
5. In height of release. Group-A was higher than Group-B.
6. Group-A was longer in horizontal transfer distance of individual joints jump till Release, and faster than Group-B enen in transfer velocity.
7. As for the angle of elbow joint while swing, Group-A stretched the arm longer than Group-B, making the resistance arm longer extended. In velocity change of shoulder. elbow and wrist of the throwing arm, Group-A made more use of joint of such components than Group-B.
8. Concerning the angle changes of the shooting shoulder, Group-A wound the shoulder widly lowback-wards and then released at 30˚-35˚ ahead of perpendicular line, whereas Group-B pulled in the ball-grasping hand towards the shoulder and made a narrow swing and then released near the perpendicular line.
9. In the extent of shoulder-mobilizing angle, Group-A was wider than Group-B, where Group-A made a circular motion on an axis of the waist and Group-B on an axis of the shoulder.
10. Group-A showed higher leap-up of the leg opposite to the take-off leg than Group-B, consquently releasing a larger transition in the center of grauity.
