摘要： A training aid for persons using a hand-held sporting implement which strikes a ball. The training aid controls the bending of the wrist. The training aid includes a housing which is removably secured to the person's wrist and forearm. A sliding latch is formed in the housing and is removably restrained in the housing. A member is pivotally attached to the housing. An opening to receive the thumb is formed in the pivotally attached member. A bowed connector connects the pivotally attached member to the sliding latch. When the training aid is mounted on the person's wrist and forearm and the person holds the sporting implement in a position to swing the sporting implement, the bowed connector restrains movement of the pivotally attached member and restrains uncocking of the wrist. When the person swings the sporting implement close to impact with the ball, the wrist uncocks and pulls the bowed connector to release the sliding latch.
