US Patent 7677939 Arm brace for swimming

The present invention is directed to an arm-brace for improving the efficiency of a swimmer's stroke. In accordance with the embodiments of the invention, the arm brace includes a first closed loop and a second closed loop that together form a figure-eight configuration. The first closed loop and the second closed loop are preferably at an angle with respect to each other such that the swimmer's hand is positionable through a portion of the first closed loop and the swimmer's forearm is positionable through the second closed loop. The arm brace is configured to control an angle between the swimmer's elbow and wrist in order to promote early vertical forearm positioning as the swimmer's arm moves through a catch phase of a swimming stroke.
