Crow Hop
For long throw preparation, the crow hop is recommended, since it:
- Regains the body balance and sets up side-on position,and
- Adds fprward momentum in the direction of the target through a quick weight transfer.
- Short distance short crow hop, long distance long crow hop
- Hop generates good reaction force from ground
- It increases force summation
- Biomechanical considerations lay down that for a long throw requiring maximum force, the whole body shuld be used in throw. In short throws, the emphasis is on a quick release rather than maximum force. In this instance, the thrower employs the quiker moving muscles of the arm and hand. There is no need to use the larger muscles of the legs and trunck.
- Hay ( 1973 ) states that a quick return depends on:-
- The time spent on applying force to the ball
- The time the ball spends in flight
- To throw a maximum distance (daish 1972) , it is recommended that the projection angle of the ball should be 40-45 degrees into a headwind. The optimal angle is less in order to keep the ball low.
