ABSTRACT:
A hydrodynamic jumper which can be interchangeably used by men, women, and children alike in the water without substantial structural modification by simply adjusting its shoulder straps. The hydrodynamic jumper permits a large range of movement and controlled use of resistive forces. The hydrodynamic jumper includes an annular hydrodynamic member and shoulder straps which carry the annular hydrodynamic member about the waist of the user. In the illustrative embodiments, the annular member is semi-torroidal, trough-shaped or flat. The jumper can have blades, baffles, bumps, slits, or deflectors for increased hydrodynamic fluid resistance and pressure. The jumper can also have foldable hinged sections for compact storage, shipment, and handling.
