  • Patent number: 7377784
    Abstract: Systems and methods for providing and using a teaching aid that enables swimmers to develop correct mechanics and movement patterns of a flip turn. A teaching aid is provided that functions to expedite the teaching and learning of proper flip turn mechanics by providing an object for a swimmer to place his/her hands on and press down for support, tactile feedback and spatial orientation as the swimmer learns to initiate and perform a proper flip turn. Utilization of the teaching aid allows a swimmer to feel and move through the proper mechanics of the flip turn, thereby expediting the swimmer's ability to perform the turn without assistance.

  • Patent number: 6866615
    Abstract: Apparatus and method are provided for teaching and/or improving upon the mechanics of the whip kick that may be used while performing the breaststroke and training the competitive breaststroker. The tool includes a fin that is configured to receive a swimmer's foot and a propulsive blade that engages the water at the beginning of the propulsive phase of the kick, such as when the swimmer's legs have reached maximum flexion at the knees, with feet positioned slightly wider than the knees, heels turned in while the toes are turned out and ankles flexed. As the swimmer initiates the power phase of the kick, the propulsive blade achieves maximum purchase of the water.
