Abstract
An underwater closed-loop track consists of at least two tracks (12 and 14) which are formed of floating pads (16 and 18) connected in series and containing weights (22) for maintaining the pads at a predetermined depth from the surface of water. The underwater track is supported by flexible links, e.g., by ropes, connected to stationary supports (S1 and S2). The external track (12) has a depth suitable for walking and running in water on the bottom formed by the pads, while the external track (14) has a depth for running in water without touching the bottom. Another embodiment of the invention relates to a stationary swimming pool of a closed-loop configuration (40) or a zig-zag configuration (66) having at least two tracks, one of which is suitable for running and walking in water with touching the bottom, and another for running in water without touching the bottom. The bottom may have an uneven profile, while resistance to walking and running can be changed by means of jet nozzles (53 and 55) installed on the path of the user.
