摘要
A swimming assistance accessory includes a holder to hold the accessory during swimming; a float allowing the water to exert, on the accessory, a vertical force resulting from buoyancy opposing gravity; and a weight allowing the barycenter of the holder to be maintained substantially below the surface of the water when the accessory is in a balance position in water.
