ABSTRACT:
A throwing arm training device is attached to the user's arm to limit the flexion angle of the throwing arm to a maximum angle of 90 degrees or more and also the angle of extension to a desired minimum angle, 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 of the cuffs. The cuffs are attached to the arms by straps having Velcro fasteners, 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 pitchers 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. In a second and third embodiment, the maximum flexion angle may be set at least as high as 120 degrees and the minimum extension angle may be set at least as low as zero degrees, enabling a user's arm to travel through a range of at least 120 degrees between a maximum flexion angle and a minimum extension angle.
