ABSTRACT:
An athletic training device is provided for determining the forward rotation of the hand in relation to the wrist of an athlete. The device comprises a pair of bands, a first band disposed about the wrist and a second band disposed about the knuckles of a hand of an athlete. A strap is connected between the two bands. The length of the strap is greater than the distance between the two bands when the hand is not rotated forwardly. When the wrist is rotated forwardly, the strap is placed under tension and pulled toward the hand of the athlete. This movement of the strap triggers a sensing mechanism, which in turn closes a circuit and triggers a signalling mechanism. Thus, an athlete can determine when complete forward rotation of his or her wrist has occurred. In a preferred embodiment, the signalling mechanism includes an audible sound generating device.
