ABSTRACT:
A throwing arm training device is attached to a user's arm to limit the flexion angle of the throwing arm to a maximum angle of 90 degrees and also the angle of extension to a desired minimum angle less than 90 degrees, thereby, encouraging maximum use of the latissimus dorsi muscle while discouraging sidearm throwing. The device comprises an upper arm and a forearm cuff having bars extending therefrom pivotally connected in the vicinity of the elbow by pivot screws mounted on a plate and connected to a limit plate having two arcuate slots centered on the pivot screws. Limit screws are slidably and lockably mounted in the slots to engage and limit the pivoting of the bars, and therefore of the cuffs. The cuffs are attached to the arms by straps having VELCRO or hook fasteners and loop, and include cushioning liners therein. The preferred materials for forming the straps include polypropylene, polyethylene, and copolymers of polypropylene and polyethylene. The device may be used by football quarterbacks and baseball pitcher to teach them the proper way to throw by maximizing shoulder use or movement in the throwing motion which results in an increase in the distance thrown.
