ABSTRACT:
The present invention is directed to a tethered ball training device that has an adjustable chaotic motion. The invention includes a supporting frame and a non-elastic line suspended from the frame. A resilient ball is mounted at the bottom end portion of the line and a weight slidably attached to the line is positioned in between the lower ball and the upper frame. In a method of training, a player first hits the tethered ball in a first direction of rotation. The ball will undergo chaotic motion as it rotates in this first direction. The player then tries to hit the ball to rotate it in the opposite direction and provide it with a different chaotic motion. This hitting of the ball is repeated. In a method of training a crane operator, a load is placed in motion and a trainee practices bringing the load under control.
