Ball for racquetball with training markings

Abstract

Markings are added to the conventional solid color racquetball ball, which gives the player additional information on the likely trajectory of the ball, and the player is thus able to make a more precise return stroke. When a ball is marked in some visible manner, the player is better able to judge the rotation caused by the walls of the racquetball court, and can adjust his stroke or swing to improve the accuracy of the return. In racquetball the rotation of the ball is particularly important because many shots are received after having bounced off one, two, or three walls, and the rotations are thus difficult to predict. In racquetball the conventional ball is a solid color and the rotation of the ball is not discernible to the player's eye. The markings introduced by this invention make the wall-induced rotation more discernible.
