  • Patent number: 4867720
    Abstract: A device and method for swimmers to enhance propulsion from the swimmer's kick. The device resists flexure of the swimmer's knees by providing a first band secured typically to the thigh, a second band secured typically to the lower leg, and a flexurally resistant member coupled to the first and second bands. By resisting knee flexure, the swimmer is forced to power a flutter kick with hip muscles rather than leg muscles, resulting in a generally more powerful and efficient flutter kick. In one embodiment, the bands secured to the legs may include Velcro.RTM. for a snug ift. Also, the flexurally resistant member by comprise a graphite or fiberglass rod. A sliding member, such as a ring around the flexurally resistant member, may be provided with a line to prevent loss of a detached flexurally resistant member. Also, the flexurally resistant member may be snapped into fittings for quick assembly or release. The device may be attached to the lower leg by a swim fin adapted to be worn on the swimmer's foot.
