ABSTRACT:
A tennis training aid that also operates to reduce the likelihood of developing tennis elbow. The training aid is comprised of a flexible strap that extends from a fitting on the head of the player's racquet to a member engaging his wrist. The fitting is attached to the racquet head at approximately its widest transverse point. The connecting strap is an aid in establishing a desired angular relation between the player's arm and the longitudinal axis of the racquet. At the same time, the connecting strap minimizes the possibility of stretching or overextending the extensor muscles of the players's forearm which stretching frequently leads to the injury known as tennis elbow.
